Air conditioner produces condensate because the moist air inside of the

enclosure meets cold heat exchanger (evaporator) and then it becomes water;

water production decreases during air conditioner working because

enclosure air becomes dry.

The enclosure must be IP 54 protected, if enclosure is not airtight, condensate

production could increase.

The enclosure IP54 degree is guaranteed only if the air conditioner is proper

mounted.
