PURPOSE:To prevent the supply of low-temperature hot water by raising the operational efficiency of an air conditioning and hot water supplying apparatus using a heat pump type chiller unit by using a system in which operation time zone sectins for hot water supply and air conditioning and the supply of water to a hot water supply tank after the hot water is supplied are set up by each program timer. CONSTITUTION:When a hot water storage and air conditioning time zone setting program timer is at a hot water storage time and the water temperature of a hot water supply tank 11 is low, heat source pumps 13 and 9 are operated, a solenoid valve 6 is opened, a solenoid valve 7 is closed, and thereby hot water 2 of a heat pump chiller unit 1 heats up the water of the hot water supply tank 11 through a heat exchanger 3. When an air conditioning time zone is reached, the valves 6 and 7 are switched to each other, a fan coil unit 5 is operated, and a hot water supplying pump 20 is operated by an operational time zone setting program to supply hot water. After the lapse of the hot water supplying time zone, water is supplied by the water supplying time zone setting program and output of a water level detector 21. |
