9 usage details that affect the life of air conditioners

1. Clean the air filter frequently. Usually clean once every 2-3 weeks. The steps are: remove the panel; pull out the air filter; clean the air filter. Rinse the air filter under the tap. Since the filter is made of plastic frame and polyester silk, it should not be cleaned with hot water above 40℃ to prevent shrinkage and deformation.

Advantages and disadvantages of screw refrigeration compressors

Screw refrigeration compressor is a rotary positive displacement compressor. It uses the change of the cogging volume and position of the screw to complete the process of vapor suction, compression and exhaust. Oil-free screw compressors came out in the 1930s, mainly used to compress air. Later, the oil-injected screw compressor appeared in the cylinder,
