2.972 How A Compression Refrigeration System Works

WebThe coefficient of performance describes the efficiency the evaporator to absorb heat in relation to the work put in, thus b = refrigeration effect / work input = qin/ work = (h3– h1) / (h4– h3). LIMITING PHYSICS: Heat transfer depends on the properties of the refrigerant. WebThe Physical Properties of refrigerants are as follows. Specific heat: The liquid specific heat should be small so that degree of sub cooling will be large leading to smaller amount of flash gas at evaporator inlet and that of the vapor should be large so that the degree of superheating will be small. Low viscosity: The refrigerant in the liquid …
