AIR CONDITIONING SYSTEM SERVING FOR BOTH ICE COLD ACCUMULATION TYPE COOLING AND SPACE HEATING AS WELL AS HOT WATER SUPPLY

摘要

PURPOSE:To simplify the titled device by combining a space heating and hot water supply system in addition to an ice cold accumulation type cooling system, by providing a second circulation circuit, which has been made selectively connectable and interruptable, in a load side circuit or a heat accumulation tank and a third circulation circuit, which has been made connectable and interruptable, in a load side circuit or a hot water supply tank. CONSTITUTION:A second circulation circuit F passing through a hot water pump 22, a valve 9f, a heat accumulation tank 3 and a valve 9g is connected with a hot water tank 18. A condenser 14 of a coolant circuit C is so constituted that a third circulation circuit G connecting with a load side circuit B through the condenser 14 is connected with the condenser 14, and hot water whose heat is exchanged by the condenser 14 is circulated to an air conditioner through a hot water pump 23 and a valve 9h. Then a second circulation circuit F connecting with a hot water tank 18 is made connectable with and interruptable to the third circulation circuit G connecting with the load side circuit B through changeover of the valves 9f, 9h, 9i.
