WebThe 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. WebExplanation: Heat rejection factor is the load on the condenser per unit refrigeration capacity. So, it can be represented as, HRF = QC / RE, Where, QC = Load on the condenser & RE = Refrigeration capacity And as we know, the load on the condenser, i.e., Q C is the summation of refrigeration capacity and work done by the compressor. QC = RE + W
