摘要： A heat pump system includes a refrigerant circuit that has a compressor, a first heat exchanger, a second heat exchanger, a reheat heat exchanger, a modulating valve, and a reversing valve. The reversing valve is configured to transition between a first configuration to direct refrigerant from the compressor toward the modulating valve and a second configuration to direct the refrigerant from the compressor toward the first heat exchanger. The heat pump system also includes control circuitry configured to concurrently maintain the reversing valve in the first configuration and adjust a position of the modulating valve to direct a first portion of the refrigerant from the modulating valve to the second heat exchanger and a second portion of the refrigerant from the modulating valve to the reheat heat exchanger based on an operating mode of the heat pump system.

摘要： A multi-type air conditioner includes an outdoor unit, one or more indoor units communicating with the outdoor unit, and a liquid-stay preventing device heating and evaporating a liquefied refrigerant so as to prevent the liquefied refrigerant circulating between the indoor unit and the outdoor unit from being accumulated at a low pressure side including the indoor unit. Accordingly, a liquefied refrigerant is not accumulated in an indoor unit and a connection pipe, which are a low pressure side where the pressure is relatively low, but smoothly passes therethrough regardless of a height difference between the indoor unit and the outdoor unit. Therefore, the efficiency of the multi-type air conditioner is improved. Also, because the refrigerant deficiency is prevented from occurring at a high pressure side, the reliability of the cooling operation is improved, and the liquefied refrigerant accumulated at the low pressure side is introduced into a compressor of the outdoor unit, thereby preventing damage to the compressor.

摘要： A heat pump cycle includes a first usage side heat exchanger that heats a target fluid via heat exchange with refrigerant discharged from a compressor. The refrigerant flowing out of the first usage side heat exchanger is reduced in pressure by a first pressure reducing unit, and then separated into gas and liquid by a gas-liquid separation unit. The separated gas-phase refrigerant flows toward an intermediate-pressure port of the compressor. The separated liquid-phase refrigerant is reduced in pressure by a second pressure reducing unit. An additional heat exchanger performs heat exchange between the refrigerant flowing from the second pressure reducing unit and a heat medium, and allows the refrigerant to flow toward an intake port of the compressor. A second usage side heat exchanger performs heat exchange between the separated liquid-phase refrigerant and a counterpart fluid, and allows the refrigerant to flow toward the second pressure reducing unit.

摘要： A refrigeration apparatus includes a compressor, a heat source-side heat exchanger, a receiver, a utilization-side heat exchange, a receiver degassing pipe interconnecting an upper portion of the receiver and a suction side of the compressor, and a receiver liquid level detection pipe connected to the receiver. The receiver liquid level detection pipe detects whether or not liquid level in the receiver has reached a predetermined position on a lower side of a position where the receiver degassing pipe is connected. The receiver liquid level detection pipe merges with the receiver degassing pipe via a capillary tube. The receiver degassing pipe has a refrigerant heater to heat refrigerant flowing through the receiver degassing pipe. Whether or not the liquid level in the receiver has reached the predetermined position is detected using a temperature of refrigerant flowing though the receiver degassing pipe.
