Jinxiang recycles silicon-controlled rectifier distribution cabinets and second-hand AC current transformers; refrigeration unit equipment. When the ambient temperature is low and the cooling water temperature is very low, starting up the unit may also cause low-voltage failure. During unit operation, due to insufficient preheating, the refrigerant oil temperature is low, and the refrigerant has not been fully separated, which can also lead to low-voltage failure. For the former situation, measures such as shutting down the cooling tower and throttling the cooling water can be taken to increase the cooling water temperature. For the latter situation, extending the preheating time, once the refrigerant oil temperature recovers, the unit generally returns to normal. 3. Low valve temperature failure: The temperature at the expansion valve outlet reflects the evaporation temperature, which is a factor affecting heat exchange, usually around 5-6℃ lower than the cold medium water outlet temperature. When a low valve temperature failure occurs, the compressor will shut down. After the valve temperature recovers, it will automatically resume operation, with a protection value of -2℃. The causes of low valve temperature failure include: (1) Minor refrigerant leakage, usually manifested as a low valve temperature failure rather than a low-voltage failure. Insufficient refrigerant evaporates at the expansion valve outlet, causing cooling and manifested by frosting at the expansion valve outlet. At the same time, the intake port temperature is higher (superheated steam), resulting in reduced cooling capacity and slower cooling.
