摘要： The separation efficiency of non-condensable gas in the separation membrane is enhanced in a refrigeration device provided with a configuration whereby non-condensable gas remaining in the refrigerant connection pipes at the time of on-site installation can be separated and removed from a state of mixture with the refrigerant in the refrigerant circuit using a separation membrane. An air conditioning device 1 comprises a heat source unit (2) and a utilization unit (5) connected via a refrigerant connection pipe (6, 7) to form a refrigerant circuit (10), and has a cooler (32), a secondary receiver (33), and a separation membrane device (34). The cooler (32) cools at least a portion of the refrigerant that flows through the liquid-side refrigerant circuit (11) as the compressor (21) is operated and the refrigerant in the refrigerant circuit (10) is recirculated. The secondary receiver (33) separates the refrigerant cooled by the cooler (32) into a liquid refrigerant and a gas refrigerant that includes non-condensable gas. The separation membrane device (34) has a separation membrane (34b) for separating the non-condensable gas from the gas refrigerant obtained by gas-liquid separation, and discharges the non-condensable gas thus separated to the outside of the refrigerant circuit (10).

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。

摘要： A refrigeration apparatus is provided with a vapor compression type refrigerant circuit. With this apparatus, reliability from the standpoint of the pipe cleaning mode of the apparatus is improved. The air conditioning system has a main refrigerant circuit that has a compressor, a heat-source-side heat exchanger, and a user-side heat exchanger. The air conditioning system also has a contaminant collecting device provided on the intake side of the compressor (21). The contaminant collecting device is equipped with a contaminant collecting container, an inlet pipe, an outlet pipe, and a main opening/closing device. The contaminant collecting container separates contaminants from refrigerant flowing in the intake gas pipe toward the compressor when the refrigerant is directed through it. The inlet and outlet pipes are each provided with a return preventing shape for preventing contaminants that have accumulated inside the pipes from returning to the intake gas pipe.

摘要： A leakage diagnosis apparatus for diagnosing presence/absence of refrigerant leakage in a refrigerant circuit performing a refrigeration cycle, wherein refrigerant leakage diagnosis using the amount of refrigerant exergy loss in a circuit component of the refrigerant circuit is realized. In a leakage diagnosis apparatus, an exergy calculation section calculates a leakage index value which changes in accordance with the amount of refrigerant leaking out of a refrigerant circuit based on the amount of refrigerant exergy loss in the circuit component. Then, a leakage determination section determines whether there is refrigerant leakage in the refrigerant circuit based on the leakage index value calculated by the exergy calculation section.
