Liquid Type Cental Air Conditioner with Heat Recovery

Overview

Liquid type cental air conditioner with heat recovery unit is a kind of air handling equipment with solution (lithium bromide, lithium chloride, calcium chloride, etc.) as working fluid. The unit is driven by heat pump and adopts advanced solution dehumidification technology. The solution absorbs or releases moisture to the air to adjust the temperature and humidity of the air. The fresh air after cooling and dehumidification is mixed with the indoor return air, and the air is supplied to the room when it reaches the air supply state. It is an air treatment equipment integrating cold and heat source, dehumidification section, regeneration section, filter section, air mixing section, air supply section and exhaust section. It has equipment for independent treatment of air temperature, humidity, filtration, deodorization, sterilization and other functions. It is flexible in application, simple in operation and energy saving, and is suitable for various large-scale building air treatment occasions.


Advantages 

1. Save energy and protect the environment

   ● The working temperature of the fresh air dehumidification section is 18-25℃, which avoids the waste of energy caused by the need for reheating when the dehumidification temperature is too low, and improves the cooling capacity of the heat pump.

   ● Dehumidification cooling and solution regeneration are driven by heat pump, and more than 90% of condensation heat is recycled, which greatly improves the cooling efficiency of the system, and does not discharge waste heat to the surrounding area.

   ● The use of countercurrent solution recovery increases the circulation speed of the heat recovery solution, and the total heat recovery efficiency reaches over 63%.

2. Strong dehumidification ability and wide application range

   ● The air can be treated with various functions such as cooling and dehumidification, heating and dehumidification, cooling and humidifying, heating and humidifying, and air mixing, which is suitable for all air treatment requirements.

   ● Low-humidity treatment can be performed to meet the fresh air dehumidification needs of tropical and subtropical summer high temperature and high humidity environments.

3. Improve indoor air quality

   ● High-concentration salt solution can kill most bacteria, viruses and other molds, and the killing rate can reach more than 99%, which provides a favorable defense weapon against airborne diseases such as influenza and coronavirus.

   ● Independent and precise control of temperature and humidity to provide comfortable, healthy and good indoor air.

4. Stable performance

   ● The salt solution does not decompose or volatilize, the moisture absorption and regeneration efficiency are stable, and it is less affected by the changes of fresh air and return air parameters, the dehumidification performance is not attenuated, and the service life is long. 


Features 

1. Flow air supply design, high gas-liquid heat exchange efficiency, more compact volume than cross-flow air supply design, and the equipment occupies a smaller area of the equipment room.

2. The super absorbent core is made of polymer fiber material through a series of processes such as compression molding, high temperature carbonization, bonding, curing, etc. It has the advantages of anti-aging, corrosion resistance, mildew resistance, and long service life.

Combined with the design of counter-flow air supply, it can effectively solve the common problem of liquid carrying in cross-flow air supply.

3. With advanced solution concentration control technology, the unit has stronger and more accurate dehumidification capacity, and the minimum fresh air humidity can be controlled at about 3g/kg.

4. The original double countercurrent heat recovery technology, the two-stage pumps operate independently of each other, increase the circulation speed of the heat recovery solution, and recover the waste heat more efficiently, reaching more than 63%.

5. International standard, reliable operation

   ● The solution tank is integrally formed, and there is no hidden danger of air leakage and liquid leakage;

   ● The heat exchanger is made of titanium tube, which will never rust.

   ● Refrigeration components, controller components, water pumps, fans and other main components are of international famous brands, which are stable and reliable.
