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： An air conditioning system with precisely controlled dehumidification functions is disclosed. The air conditioning system comprises an indoor air handling system comprising a primary heat exchanger and a secondary heat exchanger. The indoor air handling system can be coupled to an outdoor unit comprising a compressor and an outdoor heat exchanger. When a controller system receives a measured humidity that exceeds a set humidity, the controller system can increase the cooling capacity of the air conditioning system to meet a set temperature. Once the set temperature is met, the controller system can switch to a dehumidification mode wherein the primary heat exchanger is cooled and the secondary heat exchanger is activated. When the measured temperature exceeds the set temperature, the controller system can switch from the dehumidification mode back to cooling mode.

摘要： In a heat pump apparatus, switching between high efficiency operation, being efficient, and high capacity operation, having high capacity, is performed according to the state of the load. There are provided a main refrigerant circuit that uses an ejector, a first sub-refrigerant circuit that connects a portion between a heat exchanger and an ejector to a portion between a gas-liquid separator and a heat exchanger, and a second sub-refrigerant circuit that connects a portion between the heat exchanger and the ejector to an injection pipe of a compressor. When the load is about medium, refrigerant is circulated in the main refrigerant circuit to perform an efficient ejector aided operation utilizing the ejector. 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 which prevents degradation of efficiency is performed by flowing refrigerant to the first sub-refrigerant circuit.
