Description
Technical Field

The dehumidification heat exchanger is usually reprocessed by using a fin tube heat exchanger commonly used in an air conditioner, namely, a layer of solid adsorbent of 100-150 microns is coated on the outer surface of a fin, the solid adsorbent usually adopts silica gel, molecular sieve, composite adsorption material and the like, so that water vapor in air is adsorbed at low temperature (such as 15-28 ℃), and the adsorbed water vapor is desorbed at high temperature (such as 45-85 ℃) to complete heating regeneration. In a vapor compression refrigeration system, the dehumidification heat exchanger functions just as an evaporator and a condenser, respectively, but can be realized by using two refrigerants, namely cold refrigerant and hot refrigerant (such as water, glycol aqueous solution and the like).
Because 1 dehumidification heat exchanger can only realize a process in cooling absorption or heating regeneration in a cycle (for example 10min ~ 25min), so need 2 dehumidification heat exchangers at least, just can realize continuous type work, but the shortcoming that exists is that the wind channel switching mechanism is very complicated, can use 8 switching-over blast gates usually, causes external wind channel many, leaks greatly and a large amount of spaces are occupied, and this has brought the hindrance for new technological further popularization.
In addition, it should be noted that some existing all-fresh-air aircraft air-conditioned vehicles or security air-conditioners generally adopt a 3-stage compressor for refrigeration in order to deliver qualified dry and cold air in a high-temperature and high-humidity environment, and the biggest difficulty except for cooling is to remove moisture in the air, which results in large power consumption of equipment. In some cases, the rotary wheel is used for dehumidification in order to save energy and reduce the number of refrigeration stages, but the rotary wheel is often influenced by factors such as wind pressure and air tightness and cannot be used.
