DEVICE FOR GENERATING COLD OR HOT

摘要

FIELD: refrigeration engineering. ^ SUBSTANCE: device comprises intermediate heat exchangers mounted in the pipelines for cold and hot gas flows for cooling and heating the heat transfer agents supplied with pumps to the cooling and heat supply systems. To defrost snow coating on the heat exchanger of the refrigeration chamber, the heat transfer agent is used that is heated in the intermediate heat exchanger mounted in the pipeline for hot gas flow supplied through the pipeline provided with the valve that opens or closes by a command from the time relay. The intermediate heat exchanger mounted in the pipeline for hot gas flow removes the vapor-like moisture due to condensation. ^ EFFECT: enhanced efficiency and safety. ^ 2 cl, 1 dwg
