AKX005 Air Purifier

Overview

Since the outbreak of the new crown epidemic, the resumption of work and production has been delayed in a large area across the country. In this era of the rampant spread of viruses and germs, in order to create a public indoor environment where people can breathe safely and at ease, Aolan, which has been paying attention to air treatment, has joined hands with Zhejiang University to develop a new virus The disinfection technology has developed two new products for small public spaces such as homes and offices and large public spaces such as banks and offices: 005 household air sterilization purifier (Xiaoman Yao) and 05 commercial air sterilization purifier.


Features

1. The coronavirus killing technology jointly developed by Zhejiang University and Aolan Industry;

2. It has been tested and certified by the Guangdong Provincial Microbiological Analysis and Testing Center, a national authoritative testing agency:

   • Coronavirus (HCov-229E, ATCC VR-740) > 99.9% kill rate;

   • Influenza A virus (H1N1) > 99.9% kill rate;

   • Staphylococcus albus (the main infection of neonatal sepsis) > 99.9% kill rate;

   • Escherichia coli (the main infectious bacteria that causes diarrhea and intestinal diseases) > 99.9% kill rate.


Working Principle

1. The use of electrostatic field integrated modules, high-frequency electromagnetic wave modules combined with plasma generators to eliminate particulate pollutants (viruses/bacteria);

2. According to the characteristics of the corona virus, the aerosol with the corona virus in the air is irradiated with high-frequency electromagnetic waves of specific frequency and energy. The electromagnetic waves penetrate the surface of the virus, enter the virus, and destroy the structure of the RNA and DNA fragments inside the corona virus. At the same time, the size of the virus is increased. When the virus is irradiated by electromagnetic waves, it can absorb a sufficient amount of charge when it passes through the composite electric field, and the virus is carbonized, so as to achieve the goal of completely killing the corona virus.

These charged ions are collected by the dust collector under the action of the applied electric field force. At the same time, the plasma generator produces a negative ion concentration of 10 million PCS/cubic centimeter, and a positive ion concentration of 10 million PCS/cubic centimeter. The moment the negative ions and positive ions are neutralized by positive and negative charges, a certain amount of energy is released, which effectively causes it Changes in the structure of the surrounding bacteria or energy conversion, resulting in the death of the bacteria, achieving a sterilization effect, and improving the air purification effect.

Application

Home space, office, school, hospital, hotel, bank, office hall and many other relatively closed or crowded places.

Working Principle

1. The use of electrostatic field integrated modules, high-frequency electromagnetic wave modules combined with plasma generators to eliminate particulate pollutants (viruses/bacteria);

2. According to the characteristics of the corona virus, the aerosol with the corona virus in the air is irradiated with high-frequency electromagnetic waves of specific frequency and energy. The electromagnetic waves penetrate the surface of the virus, enter the virus, and destroy the structure of the RNA and DNA fragments inside the corona virus. At the same time, the size of the virus is increased. When the virus is irradiated by electromagnetic waves, it can absorb a sufficient amount of charge when it passes through the composite electric field, and the virus is carbonized, so as to achieve the goal of completely killing the corona virus.

These charged ions are collected by the dust collector under the action of the applied electric field force. At the same time, the plasma generator produces a negative ion concentration of 10 million PCS/cubic centimeter, and a positive ion concentration of 10 million PCS/cubic centimeter. The moment the negative ions and positive ions are neutralized by positive and negative charges, a certain amount of energy is released, which effectively causes it Changes in the structure of the surrounding bacteria or energy conversion, resulting in the death of the bacteria, achieving a sterilization effect, and improving the air purification effect.

They generally use air-cooled precision air conditioning and air-cooled chilled water air conditioning cooling systems. Room level or row to row level air conditioning end devices are used indoors. The PUE (energy efficiency index) of these old rooms is usually as high as 1.6 or more.


With the rapid growth of data center scale and quantity, especially the promotion of dual carbon targets, reducing energy consumption in data centers has become an urgent challenge. In order to deal with this problem, the data center industry has begun actively exploring the use of natural cooling sources and introducing new technologies to optimize energy efficiency, thereby reducing energy consumption and improving overall system energy efficiency. In particular, evaporative cooling technology can fully utilize natural cooling sources and improve the energy efficiency of traditional refrigeration equipment, and has been widely applied in recent years. For old computer rooms that use air-cooled chilled water air conditioning cooling systems, energy-saving renovations using the integrated cooling station with Aolan's unique patented technology can effectively improve natural utilization time and system energy efficiency.


Project Overview

The data center is located in Nanning City, Guangxi Province, in a single 27 story building with an area of approximately 270m ². The cabinets, air conditioning equipment, cable trays, and cables in the computer room are densely arranged and generate a large amount of heat. There are 6 columns of cabinets arranged in the computer room, of which 4 columns of cabinets have been isolated by cold and hot aisle sealing, using inter column level air conditioning for cooling. The other 2 columns of cabinets are placed separately and cooled using a combination of room level and inter column level air conditioning. The total load of IT equipment in the computer room is 82.81 kW, and the heat generated by the power distribution equipment is 7.35kW; The original air conditioning system in the computer room consisted of air-cooled modular chillers and indoor room level chilled  water precision air conditioners. The air-cooled modular chillers were installed on the roof equipment layer and transported chilled water to the end of the computer room through a water pump.

Renovation plan

In order to reduce the PUE of the computer room and make full use of outdoor low-temperature natural cooling, a dedicated indirect evaporation integrated cooling station for the Aolan data computer room is used to replace the original air-cooled modular chiller to provide a cold water source for the terminal air cooler in the computer room. The indoor terminal precision air conditioner remains unchanged. The integrated cold station includes an evaporative cooling cold water cooling system, an auxiliary compressor supplementary cooling system, a circulating water pump and a detachable plate heat exchanger for primary and secondary side heat exchange, etc., which directly provides cold water to indoor terminal precision air conditioning equipment. The terminal cold water supply and return water temperature is 18℃/24℃. The integrated cold station can provide low-temperature cold water for year-round operation, and the original air-cooled chiller is only used as a backup during equipment maintenance.


The effect shows that the indirect evaporation integrated cold station serves as a cooling source for air conditioning in the data center, making full use of natural cooling. It can freely set the mode switching temperature according to the project design requirements to meet the requirements for year-round cooling use. Based on the local meteorological conditions throughout the year, the low-temperature pure natural cooling energy-saving mode, the medium-temperature mixed refrigeration mode, and the high-temperature auxiliary mechanical compressor deep cooling mode are adopted. Compared with the original air-cooled chiller, the cold source part can save about 50% of energy. Aolan integrated cold station integrates indirect evaporative cooling technology, AI intelligent switching technology, frequency conversion control technology and remote energy consumption collection and analysis technology, providing another efficient and energy-saving solution for the communications industry.

Flour Production Workshop Ventilation and Cooling Project for Grain & Oil Enterprise

Flour Production Workshop Ventilation and Cooling Project for Grain & Oil Enterprise


Project Overview

This project focuses on a flour production workshop in a Fujian-based grain and oil enterprise, comprising blending and cleaning rooms with a single-floor area of approximately 2,000 square meters, constructed with a reinforced concrete frame structure. The workshop houses densely arranged equipment operating continuously, generating persistent process waste heat. Due to the large east-west and north-south span of the facility, natural ventilation airflow is disorganized, resulting in inefficient heat and humidity exchange during summer and creating a chronically hot, stuffy environment.

The environment poses three critical risks:

· Safety Risks: Dry conditions accelerate the suspension and dispersion of micron-level flour particles. When dust concentration reaches the lower explosive limit (LEL), combustion and explosion hazards arise.

· Quality Risks: High temperatures cause thermal degradation of flour components, affecting starch gelatinization properties and gluten protein functionality, leading to deviations in finished product quality standards.

· Health Risks: Elevated temperatures reduce worker efficiency and trigger occupational heat stress reactions.


Addressing these issues from perspectives of safety, quality control, and occupational health, thermal environment regulation has become a critical priority. Aolan’s evaporative cooling technology effectively lowers workshop temperatures, improves air quality, mitigates heat and dust impacts on workers, and significantly enhances workplace comfort.

Operational Design

The design deploys 64 Aolan Duo-series evaporative air coolers evenly distributed on the north and south sides of the 1st, 2nd, 5th, and 8th floors. These units deliver direct indoor air supply through ducts to achieve holistic cooling and humidification. A centralized PC-based control system allows real-time monitoring of all coolers via an operation platform in the 2nd-floor control room. Clients can flexibly activate or deactivate individual or multiple coolers based on operational needs, enabling efficient and user-friendly management.



Performance Results

Field measurements confirm that during peak summer, the air outlet temperature of the coolers remains consistently below 28°C. The implementation of these units has significantly reduced workshop temperatures, improved indoor air quality, alleviated heat and dust impacts on workers, and enhanced overall comfort. By maintaining positive air pressure through continuous airflow, the system also minimizes external dust ingress. The project has successfully achieved its goals of temperature reduction, dust suppression, and workplace environment optimization.

Medical Places

Industry Overview

As an important functional part of the hospital, the design requirements of the operating room are getting higher and higher, requiring large fresh air, constant temperature and humidity throughout the year, high cleanliness, and huge energy consumption of the air conditioning system. If the energy consumption of the air-conditioning system in the operating room can be reduced, it is of great significance to the energy conservation and emission reduction of large-scale public construction projects such as hospitals.


Project Introduction

The operating room of a hospital in Singapore is located in the inner area of the building. The air-conditioning loads are mainly fresh air, lighting, indoor equipment, personnel, etc. The humidity load mainly comes from the human body and fresh air. In order to ensure the cleanliness requirements, the airflow requirements are relatively large, especially the fresh air requirements, which are required to reach 60m³/h. According to the design of the traditional air conditioning solution, the fresh air is first treated to the dew point in the fresh air unit, and then enters into each indoor circulation unit after passing through the medium-efficiency and sub-high-efficiency filters. After mixing with the return air, it is frozen and dehumidified with low-temperature chilled water, and then sent into the room after reheating. This treatment method obviously has huge reheat, serious cold and heat offset, and high energy consumption.

Based on the advanced LDAC Heat Recovery technology, Aolan designs and uses a high-efficiency Liquid Desiccant Air Conditioner to independently process the fresh air, independently undertake the fresh air load, and adjust the indoor latent heat load by adjusting the fresh air humidity, realizing the energy saving of fresh air treatment. And improve the sensible heat cooling capacity of the indoor air-conditioning system to achieve the purpose of improving the cooling efficiency and reducing the energy consumption. At present, the project is running well, achieving an energy saving rate of more than 37%. The salt solution has a bactericidal function, which is conducive to killing bacteria, viruses, microorganisms, etc. in the air, and is conducive to controlling the spread of viruses in buildings.

It has the characteristics of high COP, convenient adjustment, and high killing rate of bacteria, viruses and microorganisms. It is suitable for This type of hospital complex building has a large demand for cooling capacity and a lot of fresh air, so as to achieve the purpose of energy saving, purification and comfort. The renovation of the previous air conditioning system can solve the problem of insufficient design capacity and achieve the purpose of energy saving and comfort.


Project Introduction

A food court has 4 floors with a total area of about 2800m² and a single-storey building area of about 700m². The first floor is a food stall and a cafeteria, the second and third floors are separated small restaurants, and the fourth floor is a high-end restaurant. The previous air-conditioning system is in the form of Fan Coil unit plus Fresh air, and the cooling source is an air source heat pump unit. At present, the air-conditioning system has the problem of insufficient design quantity and out-of-control indoor temperature and humidity. Especially when the fresh air is turned on, the indoor humidity will be higher. The original design cooling load is about 900KW, and the cooling source is 2*560KW of air source heat pump units. Because the actual passenger flow far exceeds the design value, the indoor temperature and humidity are high and the comfort is poor. The transformation requires the temperature to be controlled at 25℃±1.5℃ and the relative humidity at 50%±10%.    


According to the actual situation of the existing building, if the traditional air-conditioning renovation scheme is adopted, a total of 500KW refrigeration units need to be added, the fan coil unit will be increased accordingly, the system power distribution capacity will be expanded by 30%, and the renovation and operating costs will be greatly increased. The Fresh Air Desiccant Unit is used to replace the previous Fresh Air System. The air supply point of the fresh air is 20°C, 20% (3.0g/kg), and the humidity is much lower than the indoor humidity, which greatly reduces the latent heat compound of the previous air conditioning system. The sensible heat output of the original system has been increased. After the renovation, without adding refrigeration units and indoor end coils, the indoor temperature and humidity meet the owner's requirements, greatly improving air quality and comfort, and greatly saving equipment renovation costs and later operation costs.

Evaporative Pad Fresh Air in Small Aggregation Equipment Room of Communication Base Station

Industry Overview

Generally, 1-2 computer room air conditioners or ordinary split air conditioners are installed in communication base stations and small aggregation equipment rooms. The air conditioners are placed directly on the side wall of the room, regardless of the direction of the cooling airflow of the cabinets. There is a nest flow in the cabinet channel, and high temperature alarms. Such phenomena occur from time to time, affecting the normal operation of the cabinet. The computer room is airtight, and the compressor operates uninterruptedly throughout the year for refrigeration, with high failure rate, large power consumption, and high operation and maintenance costs. Making full use of natural cold sources, reducing or canceling the running time of mechanical compressor air conditioners, reducing energy consumption, lowering PUE value, and reducing maintenance costs for air conditioner failures have become the main direction of energy-saving renovation of base stations and small computer rooms.

Tobacco Warehouse

Industry Overview

Tobacco alcoholization is an effective means to improve the quality of tobacco leaves. To ensure the alcoholization effect, the indoor temperature and humidity of tobacco aging warehouses need to be strictly controlled. According to "Design Specifications for Tobacco and Tobacco Products Warehouse YC/T 205-2006", the tempering temperature of red-cured cigarettes should be 10-30℃, and the relative humidity should be 55-65%. The traditional air-conditioning design method generally adopts Refrigeration dehumidifying units. First, the heat pump air-conditioning unit is used to directly cool and dehumidify the air, because the temperature after dehumidifying is too low, and then the air needs to be re-heated. The traditional refrigeration and dehumidifying methods have problems such as low refrigeration efficiency and high energy consumption. Aolan Liquid Type Central Air Conditioner with full heat recovery uses advanced LDAC technology to separate and independently control air temperature and humidity, which greatly reduces the latent heat treatment load of air-conditioning heat pump, improves refrigeration efficiency and saves energy.


Project Introduction

A tobacco alcoholization warehouse in Fujian has a total of 4 storeys with a floor height of 5.6 meters and a total construction area of 13442 m². The design requires that the indoor temperature is ≤28°C and the relative humidity is ≤70%, and 8 sets of Aolan Fresh Air Desiccant Air Handling units of 45000m³/h are used. The operation of the unit is divided into three modes: ventilation, cooling and dehumidifying, and deep dehumidifying. According to the different increasing speed of indoor temperature and humidity load, the unit automatically switches between three modes. The salt solution has a strong hygroscopic capacity, and the solution regeneration can use the low temperature heat rejection of the condenser. When the unit heat pump is selected and calculated, most of the cooling capacity can be used as a sensible heat load for processing and design, which improves the cooling efficiency of the heat pump and reduces the energy consumption. Compared with the traditional Refrigeration dehumidifying Unit, the LDAC air handling technology eliminates the cold and heat offset caused by reheating in the refrigeration and dehumidifying, and uses a high-temperature cold source to treat the indoor sensible heat, reducing the system energy consumption by more than 40%; Condensate water, reduce the growth of mold, and the salt solution itself can kill more than 90% of the bacteria in the air, improve the air quality of the supply air, and improve the alcoholization conditions of tobacco leaves.

Lithium Battery Industry

Industry Overview

With the rapid development of new energy technology, the demand for process air conditioners is increasing, and the requirements for process and energy saving are also getting higher and higher. For lithium battery production workshops, laser welding rooms, assembly rooms, etc., the temperature is required to be 25±2°C, and the relative humidity is required to be ≤30%.

The Freezing Dehumidifier method uses low-temperature cold water or refrigerant to contact the air through the surface cooler coil, so that the air is cooled to the dew point and then dehumidified. The air temperature after freezing and dehumidifying is too low, and the dehumidified air needs to be reheated to reach the air supply state point. In the reheating process, there is a problem that the heat and cold are offset and the energy consumption is too large. 

Another common Desiccant Wheel is to use impregnated microporous moisture absorbent material to absorb moisture in the air to dry the air, and use high-temperature air in the regeneration area to take away the moisture for regeneration. Due to the high regeneration temperature of rotary dehumidification, the air needs to be cooled again after dehumidification to reach the air supply state point. The cooling process after dehumidifying requires a large amount of cooling, and there is a problem of huge energy consumption.

In the solution dehumidifying system, the solution is used as a hygroscopic material, and the difference between the vapor pressure of the solution surface and the vapor pressure of the air to be treated is used as the driving force for mass transfer to dehumidify the air. The solution dehumidifying system has the advantages of independent control of air temperature and humidity, high energy efficiency, avoiding the process of reheating or recooling the air after dehumidifying, and high air supply cleanliness. It is an important alternative to the above two common dehumidifying systems. It is widely used in battery factories or energy-saving renovation of existing dehumidifying systems.


Project Introduction

A lithium battery production plant is located in a city in the south, which is hot in summer and cold in winter. In the production process of lithium battery cathode, graphite powder, mixed binder and other solvents need to be prepared into graphite slurry, and then applied to the surface of aluminum foil. The workshop requires a temperature of 24±3℃ and a relative humidity of ≤40% (absolute humidity between 6g/kg and 9g/kg).    

There is a 30000m³/h Liquid Type Central Air Conditioner installed, with a fresh air ratio of 25%. The air treatment process of the Liquid Desiccant Air conditioner system as follow: 



In cooling and dehumidifying section, fresh air A0 (36℃, 60%) is cooled and dehumidified to A1 (15℃, 40%). Fresh air mixed with the indoor return air A2 (24℃, 35%) to Supply air Aout (20℃, 30%). 

In the regenerating section, the temperature of the solution heated by the condenser, and the moisture is released to the fresh air from the outdoor state point of R0 (36°C, 60%) to achieve regeneration. After moisture absorption, the state point is ROUT ( 43°C, 60%) of the regeneration air is exhausted. 

In this system, the evaporator of the heat pump provides the cooling capacity required for dehumidification of the solution, the condenser of the heat pump provides the heat required for the regeneration of the solution, and the processed air directly reaches the point of supply air. No need re-heat and re-cool power consumption.

Bus Station

Industry Overview

People-intensive buildings, such as bus stations or train station waiting rooms, are characterized by high personnel density, large indoor humidity, and high demand for fresh air. Traditional air-conditioning systems consume a lot of energy, especially in the summer season of high temperature and high humidity. Most of the cooling capacity is used to deal with fresh air and indoor humidity load, resulting in insufficient sensible heat capacity and reduced comfort. 

The independent control concept of temperature and humidity of solution adsorption dehumidification and evaporator processing sensible heat provides a more energy-saving and comfortable air-conditioning design scheme for densely populated buildings such as stations and airports. The Heat Recovery Type Fresh Air Desiccant Unit uses salt solutions such as lithium chloride and lithium bromide as the working medium, and uses the characteristics of low vapor pressure on the surface of the salt solution to absorb the moisture in the air to achieve the purpose of dehumidification; the unit comes with a heat pump condenser end to exhaust heat for solution heating Regeneration does not need to increase additional energy consumption; the high temperature cold source at the evaporator end only needs to process the sensible heat of the air, and the cooling efficiency of the heat pump is greatly improved.


Project Introduction

A new large-scale bus station is built in a city, with a construction area of 108,600 m² and a maximum design capacity of 10,000 people. The city is located in southern China, with high temperature and high humidity in the rainy season. The number of days in which the wet bulb temperature is higher than 28℃ is more than 110 days. The latent heat load is the main consumption of the cooling capacity of the air-conditioning system of the project. The Heat Recovery Type Fresh Air Desiccant Unit is matched with a magnetic levitation chiller. The Fresh Air Desiccant Unit dehumidifies and cools the fresh air to 3.5g/kg, and feeds it into the room at 20°C, increases the indoor circulating airflow, improves the indoor dehumidifying efficiency, and keeps the room dry. The chiller only operates in the high temperature area, which greatly improves the cooling efficiency. The salt solution has the characteristics of non-volatile and strong stability, and also has the ability to kill microorganisms such as bacteria and viruses, which can purify the air and provide high-quality indoor air.

Train Station

Industry Overview

The waiting hall of the train station has the characteristics of high density of people, large indoor humidity, and high demand for fresh air. At present, this type of place generally adopts the method of Freezing dehumidifier (using 7°C chilled water) to remove the sensible heat load and latent heat load in the station. This conventional air treatment method results in that the sensible heat load can be discharged by a high-temperature cold source (14/19°C), but has to be treated with a low-temperature cold source of 7°C with the dehumidifying process, resulting in a waste of energy quality. The climate in southern China is hot and humid, and the heat-humidity ratio required for indoor environmental regulation of the building varies within a large range. There are problems of over-allocation of cooling capacity or insufficient cooling capacity in extreme weather, which brings extremely difficult design. Moreover, there is a problem of mold growth on the surface of the evaporator in the Freezing Dehumidifying method, which seriously affects the indoor air quality.

The temperature and humidity independent control air-conditioning system is a new type of air-conditioning system that uses solution as the working medium to treat air humidity and high-temperature cold water to treat air temperature. The Liquid Desiccant Air Conditioner is driven by a heat pump, and the vapor pressure on the surface of the solution after cooling is extremely low. During the process of contacting with the air, it absorbs the moisture in the air and cools the air at the same time. The regeneration utilizes low-grade waste heat discharged from condenser, realizes the conversion of thermal energy to steam energy, and reduces the heat emission of the unit. On the one hand, the energy consumption is greatly reduced, and on the other hand, it can flexibly adapt to changes in the indoor heat-humidity ratio, and at the same time, it can significantly improve the indoor air quality.


Project Introduction

A train station in a city in the south has a building area of 10,000m². The city is located in the south of China. During the rainy season, the temperature is high and the humidity is high. The wet bulb temperature is higher than 28°C for more than 100 days throughout the year. The existing air-conditioning system uses low-temperature cold water as the cold source temperature and humidity treatment method, which consumes a lot of energy. In extreme weather conditions, due to the soaring wet load or even insufficient cooling capacity, the comfort is greatly reduced. The renovation of this project adopts the independent control method of temperature and humidity, and 6 sets of 6000 airflow Pre-Cooling type Fresh Air Desiccant Unit are added to deal with the latent heat of the air, and the existing air conditioning system is changed to a high temperature cold source to deal with the sensible heat of the air. After changing to high-temperature cold water, compared with the low-temperature cold water produced by the evaporator in the past, the existing refrigeration system has improved the refrigeration efficiency and reduced power consumption. The powerful dehumidifying capacity of the Liquid Desiccant Air Conditioner meets the processing requirements of different humidity loads at different times throughout the year, making it no longer difficult to handle humidity loads under extreme climatic conditions. The salt solution has the characteristics of non-volatile and strong stability, and also has the ability to kill microorganisms such as bacteria and viruses, which can purify the air and provide high-quality indoor air.

Pharmaceutical Factory

Industry Overview

The production process of the pharmaceutical factory workshop has very strict requirements on the temperature and humidity of the environment. Too high air humidity is very detrimental to the production quality and storage safety of drugs. During the pharmaceutical production process, a large amount of waste heat is emitted. How to efficiently recycle the waste heat has also become an important task for pharmaceutical factories to control costs and protect the environment. With the continuous development of domestic pharmaceutical GMP certification, higher requirements are placed on the environment of pharmaceutical production enterprises, and the standards of their air conditioning and ventilation systems are correspondingly improved. How to control energy saving and environmental protection to reduce air temperature and humidity has important economic and social value to pharmaceutical factories.  


Project Introduction

The workshop of a large pharmaceutical factory in Taiwan is equipped with a combined air-conditioning unit. At present, the air-conditioning scheme uses an evaporator to simultaneously cool, condense and dehumidify the air to produce dry and cool air. In summer, it’s hot and humid. It is often to meet that humidity can’t reach to design requirement, high energy consumption of air conditioning system, and poor indoor air quality. In order to solve the problem of insufficient cooling capacity and high energy consumption, a Liquid Desiccant Air Conditioner (LDAC) is added to the previous air-conditioning unit to achieve independent temperature and humidity control. The LDAC treats the indoor air humidity to around 3g/kg, and the original air-conditioning unit only needs to deal with the sensible heat load, which improves the refrigeration efficiency of the unit and greatly reduces the indoor temperature. The solution regeneration utilizes the low-grade waste heat generated in the pharmaceutical production process to achieve the goals of reducing waste heat emissions and saving energy consumption. Especially in the summer thunderstorm season, high temperature and high humidity, the humidity load accounts for about 50% of the total load. After adding the Liquid Desiccant Air Conditioner, the original air conditioning unit only needs to deal with the sensible heat load, and there will be no shortage of cooling capacity. Greatly reduces indoor temperature and improves cooling efficiency.
