Glycol as refrigerant
WebThe glycol coolant is pumped through tubing connected to the input and output sections of the chiller. Heat Exchangers – Evaporator. The heat exchanger allows the transfer of heat between the glycol water coolant and the refrigerant gas. It uses the flowing glycol to collect heat from the refrigerant and move the heat away from the area being ... WebGlycol refrigeration systems are limited to servicing refrigerated spaces above 0 degrees C. Glycol temperature generally runs about 8 degrees colder (usually -8° C) than the required refrigerated space temperature. The properties of glycol when it is chilled to very low temperatures below -10° C make it unsuitable for use in refrigerated ...
