HEAT PUMP TYPE AIR CONDITIONING SYSTEM USING WASTE HEAT

摘要

PURPOSE: A heat pump type air conditioning system using waste heat is provided to prevent an over-cooling cycle operation caused by a drop of a condensing temperature so that a damage of a device is prevented. CONSTITUTION: A heat pump type air conditioning system using waste heat comprises an air conditioner(210), a cooling tower(260), a heat pump(270), a heating boiler(220), a hot water-load circulating water heat exchanger(230), a water-cooling refrigerator(240), a cooling water-heat source circulating water heat exchanger(250), and a MICOM(280). The air conditioner cools or heats air by using a cooling coil(214) and heating coil(215), thereby supplying the cooled or heated air to indoor. The heat pump heats or cools water supplied according to a circulation direction of refrigerant. The hot water-load circulating water heat exchanger heat-exchanges hot water returned after being discharged from the heating boiler and water circulating the heating coil of the air conditioner and the inner space of the heat pump each other. The water-cooling refrigerator supplies the water cooled while passing through an evaporator for a refrigerator to the cooling coil of the air conditioner and transfers heat to the cooling water through a refrigeration cycle. The cooling water-heat source circulating water heat exchanger heat-exchanges the cooling water being transferred to the cooling tower from the water-cooling refrigerator and the water circulating the inner space of the heat pump.
