Least rate of heat rejection
Nettet4. mar. 2024 · A cyclic heat engine operates between a source temperature of 800°C and a sink temperature of 30°C. The least rate of heat rejection per kW net output of … NettetThe heat rejection ratio (HRR) is the ratio of heat rejected to the heat absorbed (refrigeration capacity). Description: For a fixed condenser temperature, as the evaporator temperature decreases the COP decreases and heat rejection ratio increases. How do you calculate the heat rejection of a cooling tower?

NettetWhat is the least rate of heat rejection per kW net output of the engine? Solution: For a reversible engine, the rate of heat rejection will be minimum 2. A reversible heat engine operates between two reservoirs at temperatures of 6000C and 400C. The engine drives a reversible refrigerator which operates between reservoirs at Nettet6500 watts x 3.4 = 22,100 Btu. Heat of Compression = 22,100 Btu. Evaporating Load = 40,200Btu Total Heat of Rejection = 62,300 Btu. Total Heat of Rejection (THR) is the heat absorbed at the evaporator plus the heat picked up in the suction line plus the heat added to the refrigerant in the compressor. Share.
