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： A refrigeration cycle device includes: a compressor that constitutes a refrigeration cycle and compresses a supplied refrigerant; a refrigerant-retaining container that retains the refrigerant into which lubricating oil for the compressor is mixed, and which separates the gas refrigerant from the liquid refrigerant, and sends out the gas refrigerant to the compressor; a refrigerant conveying pump that conveys a fluid mixture including the liquid refrigerant and the lubricating oil retained in the refrigerant-retaining container; and an internal heat exchanger that changes the liquid refrigerant conveyed out from the refrigerant-retaining container by the refrigerant conveying pump to the gas refrigerant, and provides the compressor with the gas refrigerant together with the lubricating oil. Since the refrigerant conveying pump conveys the fluid mixture containing the liquid refrigerant and the lubricating oil retained in a refrigerant-retaining container, stable operation is possible.
