Do you know that water chillers are prone to these problems

1. Reasons why the chiller can't refrigerate 　　 1. The filter is blocked. When the filter is blocked, the dust on the condenser will accumulate, which will affect the cooling effect of the refrigeration equipment over time. If things go on like this, it may even cause refrigeration equipment to fail.

Working principle of reciprocating compressor_Working process of reciprocating compressor

Working principle of reciprocating compressor<img src="{{media url=&quot;Working_principle_of_reciprocating_compressor.jpg&quot;}}" alt="" />_Working process of reciprocating compressor Working principle of reciprocating compressor 　　 Relies on periodic changes in the working volume of the cylinder to compress the gas to achieve the purpose of increasing the working pressure. (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.
