WebZ-2 = compression factor of the actual gas when low-pressure stage discharge begins and when high-pressure stage suction ends Z3 = compression factor of the actual gas when the high-pressure stage discharge begins. Therefore, the indicated work of triple-cylinder operation mode can be expressed as. Or. 3. Indicated power and indicated efficiency WebSaturated Suction Temperature Formula. ... This allows the refrigerant to get overheated and attain higher degree of superheat than desired. Higher degree of superheat is disadvantageous for refrigeration cycle as high suction temperature also results in higher discharge temperature. A higher discharge temperature requires higher condensing duty.
