ABSTRACT:
A low temperature refrigerant gas heater system for warming structural parts of refrigerated display cabinets sufficiently to prevent the formation of moisture condensate. A desuperheating means is provided for an auxiliary gas flow line taken off from a primary refrigeration circuit in order to lower the temperature of a portion of the refrigerant gas flow to within the range of about 80.degree. F. to 130.degree. F. for this purpose. The auxiliary gas have pressure-temperature-enthalpy conditions located in the superheated region or the saturation envelope area of a pressure-enthalpy diagram within these temperature limits. The use of low temperature refrigerant gas in the auxiliary flow line avoids heater line warping and buckling and customer inconvenience and discomfort problems which are incurred by use of high temperature compressor refrigerant gas.
