Application of waste heat recovery of commercial complex to water-source multi-split systems

Combined with an engineering example, a winter waste heat recovery and utilization system suitable for commercial complexes is proposed. The system recovers the stable waste heat in the inner area of the commercial complex through the plate heat exchanger as the heat source of the water-source multi-split air conditioning system of the office area, and the cooling capacity discharged during the water-source multi-split system heating in the office area is used as the cold source of the air conditioning in the inner area after heat transfer, which shortens the operating time of the vacuum hot water unit and commercial cooling tower in the office area in winter, which not only has good economic benefits, but also has a good demonstration effect of energy saving and emission reduction.
