1. The exhaust temperature of the compressor in the low-temperature cold storage is too high, which will endanger the stable operation of the entire refrigeration system.
2 When the discharge temperature increases, the efficiency of the compressor decreases and the refrigeration effect decreases.
3 Long-term high-temperature operation will lead to increased wear and tear of the compressor and shorten the service life.
4. Excessive exhaust temperature can also cause condensate to accumulate, leading to problems such as ice blockage in the refrigeration system.
5 The main reasons are as follows:
Insufficient or too much refrigerant: When the refrigerant is insufficient, the refrigeration effect is poor and the exhaust gas temperature risesWhen there is too much refrigerant, the compressor is more burdened, the efficiency is reduced, and the discharge temperature increases.
Insufficient cooling water flow: When the cooling water flow is insufficient, the heat of the compressor cannot be dissipated in time, resulting in excessive exhaust temperature.
Cooling water temperature is too high: When the cooling water temperature is too high, the heat dissipation effect of the compressor is weakened, which will also lead to high exhaust air temperature.
Compressor mechanical failure: Compressor mechanical failure, such as cylinder jamming, will cause the compressor to fail to operate normally and produce high temperatures.
Non-standard placement of goods in cold storage: non-standard placement of goods will lead to poor airflow circulation in cold storage, affect the refrigeration effect, and also lead to excessive exhaust temperature.
6 In order to solve the problem of high exhaust temperature of the compressor in the low temperature cold storage, the following measures can be taken:
Regularly check the charge of the refrigerant: Regularly check whether the charge of the refrigerant is appropriate, too much or too little will affect the refrigeration effect and exhaust temperature.
Keep the cooling water unblocked: Keep the cooling water unblocked, regularly clean the impurities and biological dirt in the cooling tower and pipes, and increase the flow and temperature of the cooling water.
Increase insulation: Increasing insulation can reduce heat loss in the cold store, improve the refrigeration effect, and reduce the exhaust temperature.
