Questions regarding propylene refrigeration compressors
Thread Content
What are the differences in the operation of propylene refrigeration compressors during winter and summer?
Screw compressors, right? I don’t see any difference. Make sure to pay attention to insulation and heat retention
In summer, due to the high ambient temperature and high temperature of the circulating water, the compressor operates under higher load; as a result, its speed and outlet temperature are both higher than in winter
For screw compressors, the main difference between summer and winter lies in the temperature of the cooling water, which leads to changes in the outlet pressure of the compressor. In summer, the outlet pressure of the compressor (i.e., the exhaust pressure) is higher than in winter; as a result, the motor current also increases accordingly, and the cooling capacity of the compressor decreases as well.
Yes, in summer, the condensation efficiency of propylene condensers is lower than in winter. If the same inlet temperature is maintained, both the outlet pressure and temperature of the compressor are higher in summer, to the point where spraying may even be necessary
