The difference between centrifugal compressor and reciprocating compressor

The difference between centrifugal compressor and reciprocating compressor Centrifugal compressor overview 　　 Centrifugal compressor is also called "vortex compressor", a type of compressor. The structure and operation principle are similar to the centrifugal blower, but it is always multi-stage, which can make the gas obtain higher pressure, larger processing capacity and higher efficiency.<img src="{{media url=&quot;The_difference_between_centrifugal_compressor_and_reciprocating_compressor.jpg&quot;}}" alt="" />

The car air conditioner is running and there is no wind, and the pipe is still frosting. It may be a problem here

Yesterday, some netizens asked such a question: The air volume of the air outlet began to drop after 40 to 50 minutes of driving the car with the air conditioner, and the cooling effect also decreased. And a pipe from the air-conditioning compressor to the dashboard is also frosted. From the picture, this is the frosting of the low pressure pipe of the air conditioner.<br></br>
