Fresh Air Desiccant Unit

Overview

Fresh air desiccant unit is a new air treatment equipment with solution (lithium bromide, lithium chloride, calcium chloride, etc.) as the working fluid. The unit is driven by a 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. It is not an ordinary fresh air ventilator, it is a fresh air treatment equipment integrating cold and heat source, dehumidification section, regeneration section, filter 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. It is suitable for air pollution, poison, odor and other harsh environments that need dehumidification and cooling. occasion.


Advantages

1. Save energy and protect the environment

  ● The working temperature of the dehumidification section is 18-25℃, which avoids the energy waste 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.

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, and heating and humidifying, which is suitable for fresh air treatment requirements throughout the year.

  ● 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%, providing 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, does not volatilize, has stable moisture absorption and regeneration efficiency, is less affected by changes in fresh air and return air parameters, does not decay in dehumidification performance, and has a long service life.


Features

1. The counter-flow air supply design has high gas-liquid heat exchange efficiency. Compared with the cross-flow air supply design, the volume is more compact, 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.

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

4. With advanced solution concentration control technology, the unit has stronger and more accurate dehumidification capability, and the minimum fresh air humidity can be controlled at 4.3g/kg.

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 and will never rust.

  ● Refrigeration components, controller components, water pumps, fans and other main components are all internationally renowned brands, which are stable and reliable.
