摘要： An internal heat exchanger and a first flow control valve are connected in series between a condenser and a refrigerant inlet of an ejector. A gas refrigerant outlet of a gas-liquid separator is connected to a suction port of a compressor. A first bypass circuit connects a refrigerant outlet of the condenser to an intermediate pressure portion of the compressor via a second flow control valve and the internal heat exchanger. A second bypass circuit connects a refrigerant outlet of the internal heat exchanger to the liquid refrigerant outlet of the gas-liquid separator via a third flow control valve. While the second flow control valve is opened such that the refrigerant flows through the first bypass circuit, the fourth flow control valve is switched to be opened or closed, and the third flow control valve is switched to be closed or opened.

摘要： In a heat pump apparatus, switching between high efficiency operation, and high capacity operation, is performed according to the state of the load. A main refrigerant circuit uses an ejector. A first sub-refrigerant circuit connects a portion between a heat exchanger and an ejector to a portion between a gas-liquid separator and a heat exchanger A second sub-refrigerant circuit connects a portion between the heat exchanger and the ejector to an injection pipe of a compressor. When the load is medium, refrigerant is circulated in the main refrigerant circuit to perform an efficient ejector aided operation. When the load is large, a high capacity injection operation is performed by flowing refrigerant to the second sub-refrigerant circuit. When the load is small, a simple bypass operation prevents degradation of efficiency by flowing refrigerant to the first sub-refrigerant circuit.

摘要： An air conditioning system, a set temperature determining device determines a target temperature of water to be supplied to an indoor heat exchanger, based on [“target outflow temperature”=“current outflow temperature”+((“inlet and outlet temperature difference”/“indoor and outdoor temperature difference”)×“set temperature difference”)]. The indoor and outdoor temperature difference is a difference between an indoor temperature and an outdoor temperature, the inlet and outlet temperature difference is a difference between temperatures of water at the inlet side and the outlet side of an intermediate heat exchanger, and the set temperature difference is a difference between an indoor temperature and a set temperature. A control device controls an outdoor unit in response to the target temperature determined by the set temperature determining device.
