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.
