Product Description

Increases Chiller COP And  IAQ fresh air desiccant unit

 

 

1.Product features:

 

1. The counter-flow air supply design has high gas-liquid heat exchange efficiency, and the volume is more compact compared with the cross-flow air supply design, and the equipment occupies a smaller area of the computer 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 liquid-carrying problem in cross-flow air supply;

3. Advanced solution concentration control technology, the unit has stronger and more accurate dehumidification capacity, and the minimum fresh air humidity can be controlled at 4.3g/kg.

4. International standard, reliable operation:

a. The solution tank is integrally formed, and there is no risk of air leakage and liquid leakage;

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

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

 

2.Introduction 

 

Heat pump type liquid desiccant air conditioning is an air dehumidification 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,through the solution to absorb or release water to the air, to achieve the adjustment the humidity of 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 is flexible in application, simple in operation, and energy-saving, and is suitable for occasions where dehumidification and cooling are required in harsh environments such as air pollution, toxicity, and odor.
