摘要： A refrigeration device includes a compression mechanism, a radiator, a first expansion mechanism, a second expansion mechanism, an evaporator, a first internal heat exchanger, a branch pipe a third expansion mechanism, and a second internal heat exchanger. The first internal heat exchanger causes heat to be exchanged between refrigerant that flows from the radiator to the inflow side of the first expansion mechanism, and refrigerant that flows from the evaporator to the compression mechanism. The branch pipe branches from a third refrigerant pipe for connecting the radiator and the second expansion mechanism, and merges with the second refrigerant pipe. A third expansion mechanism is provided to the branch pipe. The second internal heat exchanger causes heat to be exchanged between refrigerant that flows out from the first expansion mechanism, and refrigerant that flows out from the third expansion mechanism.

摘要： A refrigeration system comprises a refrigerant circuit (10) in which a compressor (21), an outdoor heat exchanger (24) and an indoor heat exchanger (33) are connected to operate on a refrigeration cycle, and an oil recovery container (40) connected to the suction side of the compressor (21), and carries out a recovery operation for circulating refrigerant through the refrigerant circuit (10) to recover oil into the recovery container (40). The refrigeration system further comprises: a compressor control section (50) for stepwise increasing the operating capacity of the compressor (21) in an initial stage of the recovery operation so that the refrigerant temperature in the low pressure side of the refrigerant circuit (10) reaches or exceeds a predetermined value; and a fan control section (70) for continuously driving an indoor fan (33a) at least during a time period when the compressor (21) is driven. This suppresses an abrupt start-up of the compressor (21) and ensures that refrigerant in the indoor heat exchanger (33) evaporates. Thus, a temperature drop of refrigerant in the low pressure side can be prevented.

摘要： Disposed is a contaminant recovery receptacle (40) which is connected, through an inflow pipe (42) and an outflow pipe (43), to the suction side of a compressor (21). The inflow pipe (42) has an exit end which opens towards the inner bottom of the recovery receptacle (40). The outflow pipe (43) has an entrance end which is situated above the exit end of the inflow pipe (42) in the recovery receptacle (40). Firstly, a preliminary operation is carried out which causes refrigerant to circulate in a refrigerant circuit (10) for a predetermined length of time so that gas-liquid two-phase refrigerant flows into the recovery receptacle (40). Thereafter, a recovery operation is carried out, which causes refrigerant to circulate in the refrigerant circuit (10) so that gas refrigerant flows into the recovery receptacle (40). As a result, contaminants are recovered in the recovery receptacle (40).

摘要： The capacity of a compressor (21) in cleaning operation is set based on a Froude number Fr. The Froude number Fr expresses a ratio of an inertial force of a gas refrigerant flowing through a gas side communication pipe (70) to a gravity working on a liquid in the gas side communication pipe (70). The capacity of the compressor (21) in the cleaning operation is set so that the Froude number Fr is larger than 1, whereby the inertial force of the gas refrigerant flowing through the gas side communication pipe (70) becomes larger than the gravity working on the liquid in the gas side communication pipe (70) which contains mineral oil and foreign matters. In this connection, the liquid containing the mineral oil and the foreign matters is pushed up by the gas refrigerant even in a perpendicularly extending portion of the gas side communication pipe (70). Thus, the mineral oil and the foreign matters remaining in the existing liquid side communication pipe (60) and the existing gas side communication pipe (70) are recovered.

摘要翻译： 压缩机（21）在清洁操作中的容量基于弗劳德数Fr。 弗劳德数Fr表示流过气体侧连通管（70）的气体制冷剂的惯性力与在气体侧连通管（70）中的液体上的重力的比率。 在清洁操作中压缩机21的容量被设定为使得弗劳德数Fr大于1，从而流过气体侧连通管70的气体制冷剂的惯性力大于重力加载 气体侧连通管（70）中含有矿物油和异物的液体。 在这一点上，即使在气体侧连通管70的垂直延伸部分中，含有矿物油和异物的液体也被气体制冷剂推压。 因此，矿物油和留在现有的液体侧连通管（60）和现有的气体侧连通管（70）中的异物被回收。
