      Compressor quality will affect the service life of air energy water heater?

      06/29/2020

      Compressor quality will affect the service life of air energy water heater?

      Compressor quality will affect the service life of air energy water heater? The compressor is the core component of the air energy water heater, and is called the "heart" of the air energy equipment. The quality of the compressor directly determines the service life of the air energy heat pump. At present, the quality of compressors produced by several international manufacturers is relatively good, and can reach a relatively long service life.

      The drying effect is achieved through the principle of pressure swing adsorption. Not only can it be matched with a small air compressor, but it can also meet the needs of local users with special requirements behind the large air compressor, so as to avoid the high air quality requirements of individual points and the high configuration of the entire equipment to save investment.

(The reciprocating movement of the piston in the cylinder causes the decompression to suck the gas, and then compress the gas to a certain pressure and send it out.) The working principle of the piston compressor.
