WebbThe 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. WebbThe refrigeration cycle is a thermodynamic cycle that is used to remove heat from a specific area you want to cool. The refrigeration cycle is also known as a heat pump …
