Propylene refrigeration
Thread Content
The outlet pressure of the compressor in an acrylic refrigeration system changes with the temperature of the cooling water. How does the outlet pressure change when the water temperature is low, and why?

I happen to have one of those devices. When the temperature of the circulating water is low, the compressor outlet heat exchanger can be used to cool propylene from the gas phase to the liquid phase, thereby reducing the temperature of the liquid phase. Once the liquid phase temperature is low, heat exchange with the process fluid through the heat exchanger results in a lower temperature of the propylene gas returning from there. When this propylene gas has a lower temperature, it is compressed by the compressor, and as a result, the temperature at the compressor outlet also decreases. Therefore, once the temperature of the circulating water drops, the entire compressor performs better; the compressor’s load decreases rapidly, resulting in an excellent cooling effect.
