Solution: Replace the evaporator, perform a pressure test for leaks, evacuate, recharge the refrigerant, and the fault is resolved. Analysis and repair: Preliminarily judged as system leakage. First, checked all joints in the system piping and found no signs of oil seepage. Then charged the piping system with nitrogen and maintained the pressure at 1.2MPa, subsequently using concentrated soapy water to check for leaks.
