PROBLEM TO BE SOLVED: To provide a heat pump system which can operate in a plurality of operation modes and has a technology which can appropriately carry out a switch to each operation mode.SOLUTION: A heat pump system disclosed in the specification can carry out a heat storage alone operation, a cooling alone operation, and a heat storage/cooling simultaneous operation. If a heat storage request is generated in the execution of the cooling alone operation, the heat pump system does not carry out the heat storage/cooling simultaneous operation when the temperature of the outdoor air is determined as low, and the heat pump system carries out the heat storage/cooling simultaneous operation when the temperature of the outdoor air is determined as high. Alternatively, if a heat storage request is generated in the execution of the cooling alone operation, the heat pump system carries out the heat storage/cooling simultaneous operation in which a condensation temperature of refrigerant is set lower when the temperature of the outdoor air is determined as low, and the heat storage/cooling simultaneous operation in which the condensation temperature of the refrigerant is set higher when the temperature of the outdoor air is determined as high.SELECTED DRAWING: Figure 1 |
