[0026] The working principle of the modular purification air conditioning unit is as follows:

[0027] When starting to work, the return air first passes through the metal primary filter screen 6 for preliminary filtration, so as to prevent large particles from entering and polluting the inside of the air conditioning unit, and then the airflow passes through the medium efficiency filter 4 to continue purifying the particulate impurities in the airflow, the medium efficiency filter 4 is provided with a second differential pressure transmitter 9 behind, the differential pressure between the medium efficiency filter and the return air outlet is detected, so as to accurately monitor the service life of the filter, if the differential pressure is too large, it is proved that the pores of the bag type medium efficiency filter 4 are mostly blocked by the impurities in the airflow, the service life has expired, and the bag type medium efficiency filter 4 needs to be replaced, if the differential pressure is normal, no treatment is needed.

[0028] The airflow purified by preliminary filtration passes through the surface cooler 10 next, the airflow exchanges heat with the refrigerant in the surface cooler, the moisture in the airflow is condensed into liquid water, the refrigerant used here is cold water, generally 7-10 DEG C cold water, the condensed water drops from the surface cooler 10 to the water collecting tray 11, the water collecting tray is provided with a water outlet, and the condensed water is discharged from the water outlet.

[0030] The airflow sterilized passes through the temperature increasing assembly 13 to increase the temperature of the airflow to the process temperature required by the room, generally between 20-25 DEG C, then passes through the fan 16 and the high efficiency filter 15 for purification, so as to meet the requirements of the clean room crystallization level, the high efficiency filter 15 is provided with a first differential pressure transmitter 5 in front, the differential pressure before and after the high efficiency filter is detected, so as to accurately monitor the service life of the filter, if the differential pressure is too large, it is proved that the pores of the high efficiency filter 15 are mostly blocked by the impurities in the airflow, the service life has expired, and the high efficiency filter 15 needs to be replaced, if the differential pressure is normal, no treatment is needed.

[0031] The air flow which has been treated by temperature and humidity control and purification is then blown by the fan 16 into the flexible air duct 19, and is sent into the clean room through the air vents on the flexible air duct 19, and finally reaches the return air port, so as to circulate and complete the temperature and humidity control and purification process of the whole room.
