The application discloses a double-working-condition
heat exchanger, a cold-heat combined supply
system and method with the same, and belongs to the technical field of heat exchangers. The double-working-condition
heat exchanger comprises a first fan, an atomizing spraying device, an air conditioner condenser, a filler layer, a second fan, a
demister, an air outlet, a
circulating pump and a water collecting tank. The control method further comprises an air conditioner
refrigeration method, a cold-heat combined supply method, a single hot
water production method, a combined heating method and a coupled heating method. The application improves the heat exchange efficiency and recovers the
heat pump evaporation cold energy in the
refrigeration working condition, thereby improving the condensation efficiency to realize efficient
refrigeration. The air conditioner condensation
waste heat is recovered to produce hot water for storage and utilization, the problems of high cost, inconvenient installation, complex full heat
recovery mode control, large investment and
land occupation of absorption type refrigeration
waste heat utilization and complex operation management of a conventional water-cooled air conditioner are solved, and the
system comprehensive energy efficiency is greatly improved, energy is saved, and the investment and operation cost is reduced.
