Description

technical field [0001] The invention relates to an air dehumidification device, in particular to a phase change adsorption air dehumidification device. Background technique [0002] Air temperature and humidity are two important parameters that need to be controlled in the air conditioning process. Dehumidification energy consumption accounts for 20%-40% of the energy consumption of the air conditioning system; the traditional cooling and dehumidification method has low water supply temperature, low cooling efficiency, and low air temperature after dehumidification , In order to reach the air supply state point, reheating is required, resulting in serious irreversible losses. Therefore, people have developed the temperature and humidity separation control technology, that is, the water vapor in the air is removed by a special dehumidification system, and the air conditioning system is only responsible for the sensible heat of the air. Generally, this type of dehumidificatio...

Problems solved by technology

When working continuously, switch operation between two beds is adopted, one bed is regenerated and the other bed is dehumidified; the disadvantage is that the system accumulates a large amount of heat energy during regeneration, and after switching to dehumidification mode, most of the accumulated heat will be borne by the treated air. The outlet temperature increases significantly, which increases the processing burden of subsequent links

When working as a gap, the adsorbent needs to be replaced frequently and regenerated separately, and because there is no internal cooling, the adsorption heat generated during the adsorption process will gradually increase the bed temperature, thereby reducing the water vapor between the adsorbent and the air. Poor momentum will eventually affect the dehumidification effect

It can be seen that the high outlet temperature of the treated air and the low dehumidification effect are the two main disadvantages of the adiabatic fixed adsorption bed.
