High discharge temperature on compressor
Web5 de mai. de 2014 · Many causes can be associated with high compressor discharge temperatures. A high condensing temperature is one of them. When the condensing temperature is high, the compressor must compress the refrigerant from the low-side (evaporating) pressure to an elevated high-side (condensing) pressure. Web21 de set. de 2013 · Discharge temperature is a function of: (1) gas suction temperature; (2) gas compression ratios; (3) gas flow rate; (4) oil flow rate; and (5) oil inlet temperature. You have zero control over 1 and 3. You have some control over 2, but the wasted energy of throttling the suction or discharge is pretty high.
