Abstract：
 The invention discloses a parallel heat exchanger melting ice cold accumulation device, comprising refrigerating unit and heat exchanger connected as a loop and heat exchanger adjusting valve, secondary refrigerant and refrigerator adjusting valve set on the pipelines of heat exchanger outlet and refrigerating unit inlet; an ice tank pipeline connected to the pipeline between secondary refrigerant pump and refrigerator adjusting valve, with ice tank adjusting valve and ice tank set orderly on it, and its another end connected to the pipeline between refrigerating unit outlet and exchanger melting inlet; bypass line connected to the pipeline between heat exchanger adjusting valve and secondary refrigerant pump, with a bypass adjusting valve set on it and another end connected to the pipeline between ice tank adjusting valve and ice tank. The device which maintains the advantages of original parallel heat exchanger system can realize five operating modes of cold accumulation, ice tank supplying ice, refrigerator supplying refrigeration, ice tank and refrigerator unifying supplying refrigeration and simultaneous accumulating and supplying, meanwhile has simplified control method of parallel heat exchanger system, increased its stability and decreased its cost.
