How good is the air conditioning dehumidification

Nowadays, the temperature of some air conditioners is set actively by the manufacturer during dehumidification. Under the dehumidification method of this type of air conditioner, the control circuit will first check the room temperature, and then set the operating temperature policy value. The setting value of the factory plan is usually the policy value of the operation arrival It is 2 degrees lower than the room temperature. If the setting is too high, the dehumidification effect is not significant. In order to prevent overheating and lowering the room temperature during dehumidification, this set value is usually judged. At this time, we do not need to set the temperature, just open the air conditioning dehumidification function.<img src="{{media url=&quot;How_good_is_the_air_conditioning_dehumidification.jpg&quot;}}" alt="" />

Why does the heating system lose water

1. Why does the compressor produce overheat protection? The working principle and classification of the overload protector. The overload protector of the compressor for air conditioning generally adopts a snap-type bimetallic protector,When the pipeline is filled with water, a large amount of dissolved oxygen is mixed into it to cause corrosion; the insulation shell of the directly buried pipeline is disconnected and is subject to long-term soaking of groundwater to cause corrosion.
