Principle of refrigeration compressors
Thread Content
Could everyone share what temperature level of cryogenic cooling is used in the CDI technology you employ? What brand of refrigeration compressor is being used? The refrigeration system we use is R-507, which evaporates at 1.1 bar to cool the exhaust gas to -42°C; the compressor then raises the system pressure to 17 bar through two stages of compression. Recently, there has been an abnormal situation: the twin-screw compressors do not load automatically and sometimes fail to function. I am seeking help from experts in refrigeration compressors to analyze what might be causing this issue. Thank you. At the same time, those who have some expertise in compressors are invited to join QQ627549878 for discussions.
Generally, when loading or unloading the slide valve, a pushing force is applied. Is there a problem with the valve in the oil circuit, or is it some other issue?
Some slide valves are driven by hydraulic oil. The slide valves in our ice makers sometimes get stuck and fail to function in automatic mode, which leads to an increase in the machine’s power consumption and triggers safety interlocks. It is possible to manually operate the slide valve on site to get it moving again, and this can be quite effective
