There are several reasons for the slow heating of air conditioners: The dirt of the transpiration device and the condenser is too thick, which will cause air flow blockage, affect the heat declaration, and make the air conditioning heating a big discount. The filter is not cleaned for a long time<img src="{{media url="The_main_reason_for_the_slow_heating_of_air_conditioners.jpg"}}" alt="" />

Abstract: The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. Air-conditioning compressors are generally installed in outdoor units. What is the principle of air-conditioning compressor? What is the reason why the air conditioner compressor does not start? How to replace the air conditioner compressor? The compressor is the heart of the refrigeration system of the air conditioner. The refrigerant circulation or flow in the system is achieved by the operation of the compressor. Once the compressor stops, cooling is over. The compressor compresses the refrigerant as<img src="{{media url="magefan_blog/The_principle_of_air-conditioning_compressor.jpg"}}" alt="" />
