3 Terms and definitions

"ASHRAE Heating, Ventilation, Air Conditioning and Refrigeration Terminology" [1] (GB/T 18517-2001 refrigeration terminology) and the following Terms and definitions apply to this document. 3.1 Condensing temperature The saturation temperature corresponding to the refrigerant pressure at the inlet of the condensing heat exchanger, unit. °C. 3.2 Calorie heatrejection The total heat rejection of the evaporative refrigerant condenser is the product of the mass flow rate of the refrigerant and the enthalpy difference of the condenser inlet and outlet, minus the supplementary water. Correction (if there is supplemental water in the unit during the test). 3.3 Remote mechanical ventilation evaporative refrigerant condenser remotemechanical-draftevaporativecooledrefrigerantcon- Denser An integral part of an integrated refrigeration system that circulates water and air on the heat exchange surface of the condenser by mechanical means to heat Discharge into water and air to evaporate water and increase air enthalpy to condense the refrigerant vapor. 3.4 Subcooling For a heat exchanger, the difference between the saturation temperature at which the outlet pressure corresponds and the temperature of the liquid refrigerant at the outlet, in °C. 3.5 Superheat superheat For a heat exchanger, the difference between the temperature of the refrigerant vapor at the inlet and the saturation temperature corresponding to its inlet pressure, in °C.
