[0028] Clean air conditioners are widely used in biopharmaceuticals, electronic engineering, clean operating rooms and other places. Their function is to effectively control the ambient temperature and humidity, while ensuring the delivery of sterile and dust-free air. In high cleanliness requirements of more than 100 levels, the cleanliness level of air supply by air conditioners is very high, and there are strict requirements for the concentration of floating dust, the number of microorganisms, etc. In order to prevent dust accumulation, all components of the clean air conditioning unit must always be in a positive pressure state. At the same time, positive pressure can also prevent untreated air outside the unit from entering through the gaps in the unit panel, polluting the conveyed air, breeding bacteria and other problems. During the use of the existing clean air conditioning unit, personnel cannot confirm whether the inside of the clean air conditioning unit is positive pressure from the outside of the clean air conditioning unit. If the internal pressure of the clean air conditioning unit is abnormal, the user cannot repair the clean air conditioning unit in time, which creates the risk of dust accumulation and breeding bacteria. The clean air conditioning unit provided in this embodiment can effectively solve the above problems.
