Is air conditioning dehumidification really useful? Is air conditioning dehumidification really useful, Zhihu?

2. In fact, there is little difference between dehumidification function and refrigeration function. It is to let the compressor refrigerate, condense the water on the evaporator through condensation, and discharge it to the outside to reduce the indoor air humidity. Only when the dehumidification function is performed, in order to improve the dehumidification efficiency of the air conditioner, the air volume of the air conditioner will be relatively small.

So the temperature is very high in summer night. If you turn off the air conditioner completely, you will definitely sweat when you sleep at night.

4. Therefore, it is best to set the air conditioner to dehumidification function before going to bed at night, which can not only keep the indoor temperature within a comfortable range, but also ensure that the indoor air is not so humid, and can also avoid problems such as air conditioning disease or stiff neck caused by direct blowing of large air volume of the air conditioner.
