What is Demand Cooling and how does it works?
The Copeland Demand Cooling System uses modern electronics to provide a reliable cost effective solution to this problem. It is required for all single stage HCFC-22 applications with saturated suction temperature below -10° F. Demand Cooling is compatible with single (conventional) units as well as parallel racks. The Demand Cooling module uses the signal of a discharge head temperature sensor to monitor discharge gas temperature. If a critical temperature is reached, the module energizes a long life injection valve which meters a controlled amount of saturated refrigerant into the compressor suction cavity to cool the suction gas. The process controls the discharge temperature to a safe level. If, for some reason, the discharge temperature rises above a maximum level, the Demand Cooling module will turn the compressor off (requiring a manual reset) and actuate its alarm contact. To minimize the amount of refrigerant which much be injected, the suction gas cooling process is performed
