Refrigerating output

WebDec 8, 2014 · Broadly, COP is defined as a ratio of Desired Output/Required Input (recall energy efficiency is also similar ---- Work Output/Heat Input). For refrigeration: (required is cooling effect... WebThe refrigerating output of the expansion valve is related to the pressure difference between the inlet and outlet of the valve and the refrigerant in this working condition. So when the condensing temperature drops, the refrigerating output decreases, and the refrigerating output decreases when the evaporation pressure is too high or too low.
