Theoretical refrigeration
WebbRefrigeration may be defined as a process of removing heat from a substance and pumping it to the surroundings. It also includes the process of maintaining and reducing … WebbA food freezing system requires 20 tons of refrigeration at an evaporator temperature of -30 ∘ F and a condenser temperature of 7 2 ∘ F.The refrigerant Freon 22 is subcooled 6 ∘ F before entering the expansion valve, and the vapour is superheated before leaving the evaporator. Compression is isentropic and valve and clearance are to be disregarded.
