Importance of refrigeration cycles
WitrynaThe vapour compression cycle in the refrigeration system is working at expansion valve in the law of Steady Flow Energy Equation, h 3 + Q = h 4 + W. We know, value of Q and W is 0. So, we can write, h 3 = h 4. Performance of vapour compression cycle in the refrigeration system is, Output/Input = h1 – h4/h2 – h1.

WitrynaAll refrigeration compressors except centrifugal compressors contain oil, which lubricates the compressor and forms seals between the moving parts during the compression. The oil is important to achieve high efficiency in the compressor, but it affects the heat transfer in the system negatively. Witryna9 wrz 2024 · The important thing is how much heat is extracted from the food, and that is why it is appropriate to define the coefficient of performance of a refrigerator as the refrigerating effect (i.e. Q1) divided by the net work done on the refrigerator, per cycle. But with a heat pump, the object is to heat the room by extracting heat from outside.
