AHU Testing
The air conditioning system in the clean workshop is very important to the overall purification effect and it can directly affect the cleanliness of the workshop,
In many pharmaceutical factories and other clean room projects, there are specific requirements for the humidity of the production environment When the humidity requirement is very low, for example, when the humidity is required to be below 40%, we need to use the wheel dehumidification method to meet the customer's process requirements
Dehumidification process of air conditioning system in clean workshop: the function of air conditioning dehumidification operation is to vaporize the water vapor in the air in the purification workshop into condensed water and discharge it outdoors through pipelines, and finally obtain the goal of reducing the relative humidity of the air in the purification workshop. When the refrigerant in the heat exchanger of the purification treatment air-conditioning generator unit volatilizes, it is necessary to digest and absorb a lot of heat to reduce the external temperature of the condenser, which can cause the water in the air in the purification workshop to be cold and vaporized into water. This condensed water will flow into the water pan and be discharged outdoors through the water outlet. This is the basic principle of dehumidification of the purification treatment air-conditioning generator unit.
The cooling of the air conditioner must be accompanied by dehumidification. The temperature of the wet and cold gas may be greatly reduced after passing through the air conditioner condenser. At this moment, the relative humidity of the air is in a saturated state. The unnecessary water vapor in the air is separated out in the form of condensed water and solidified on the plate fin type of the heat exchanger, which is commonly called "essence dew". When the cooling mode is in a certain equilibrium state, the relative humidity of the air will naturally drop to a certain level, Then the air conditioner will achieve the dehumidification effect.
