Abstract

PURPOSE: To ensure multi-purpose operation of cold storage, cooling, heat recovery, stored cold extraction, heating heat storage, simultaneous cooling and heating, and heating operation by providing a circuit changeover solenoid valve on each of a chiller unit, a heat recovery circuit, and an air conditioning unit. CONSTITUTION: A chillar unit 31 is constructed with a compressor 1, a four-way valve 2, an air side heat exchanger 3, a liquid receiver 4, expansion valves 10 to 12, a water side heat exchanger 13, a heat recovery/cold storage heat exchanger 14, and an accumulator 15. A heat recovery circuit is constructed with an ice making heat exchanger 32 in a heat storage tank 32a, a heat recovery fan coil unit 35, and a brine pump 3. Further, an air conditioning circuit is constructed with a chillar unit 31, the heat storage tank 32a, an air conditioning fan coil unit 36, and a cold/hot water pump 34. Solenoid valves 37 to 42, and a four-way valve 2 are selectively changed over, whereby there are achieved various operations of ice cold storage, cooling, heat recovery, stored cold extraction, heating heat storage, simultaneous cooling and heating, and heating through check valves 16 to 22. Thus, there are reduced the installation cost and the operation cost.
