The refrigerator has a low boiling point that is about - 20℃. The freezer is surrounded by the evaporator tube so, when ...
WebA counter-clockwise Brayton cycle for a refrigerator consists of four processes that affect a parcel of gas between two plates of a stack. Adiabatic compression of the gas. When a parcel of gas is displaced from its rightmost position to its leftmost position, the parcel is adiabatically compressed, increasing its temperature. Webrefrigeration cycle, and since it operates on a transcritical cycle the compressor outlet temperature is extremely high (around 160°C). When Freon 12 (dichloro-diflouro-methane)was discovered it totally took over as the refrigerant of choice. It is an extremely stable, non toxic fluid, which does not interact with
