TRANSCRITICAL R744 REFRIGERATION SYSTEM WITH GAS COOLER OUTLET VAPORS USED AS A HEAT SOURCE FOR THE DEHUMIDIFYING COIL
A transcritical R-744 refrigeration systems for supermarkets with dehumidifying capability where the heat of the R-744 leaving the gas cooler is used for dehumidifying. The same heat exchanger is used for heat reclaim and dehumidifying purposes.
1 . A transcritical R-744 refrigeration system for supermarket with dehumidifying capability, the transcritical R-744 refrigeration system comprising a modulating valve allowing the heat of at least a portion of the R-744 refrigerant leaving the gas cooler to dehumidify the heat reclaim/dehumidifying heat exchanger.
2 . A method of dehumidifying a heat reclaim/dehumidifying heat exchanger of a transcritical R-744 refrigeration system, the method comprising the step of modulating a modulating valve to allow the heat of at least a portion of the R-744 refrigerant leaving the gas cooler to dehumidify the heat reclaim/dehumidifying heat exchanger.
