摘要： A refrigerant circuit (20) includes a low stage compressor (101, 102, 121, 122), a high stage compressor (41, 42, 43), an outdoor heat exchanger (44) and a utilization side heat exchanger (83, 93). During a defrosting operation of the refrigeration system (10), the high stage compressor (41, 42, 43) is driven. Refrigerant discharged from the high stage compressor (41, 42, 43) is pumped into the utilization side heat exchanger (83, 93) to heat frost on it from its inside. Thereafter, the refrigerant evaporates in the outdoor heat exchanger (44), is then compressed by the high stage compressor (41, 42, 43) and is sent again to the utilization side heat exchanger (83, 93).

摘要： A system for controlling operation of a refrigerating device which includes a refrigerant circuit (9) in which a compressor (1), a condenser (6), a receiver (4) for storing liquid refrigerant, a pressure-reducing valve (5), and an evaporator (9) are connected together, and a cycle changeover mechanism (2) for changing a refrigeration cycle of the refrigerant circuit (9) between forward operation and reverse operation, the refrigerating device being of such arrangement that the pressure-reducing valve (5) is positioned downstream of the receiver (4) during either one of the refrigerating cycles. The system prevents liquid back-flow to the compressor at the time of a cycle changeover, while allowing the refrigerating device to have accumulatorless construction. The top portion of the receiver (4) is connected to a liquid line on the downstream side of the pressure-reducing valve (5) through a bypass path (4a), and an on-off valve (SV) is provided in this bypass path (4a). The on-off valve (SV) is controlled to be opened for a predetermined time before the cycle is switched to a reverse cycle defrost operation. With this arrangement, a liquid refrigerant is recovered by the receiver (4) to prevent liquid back-flow. The on-off valve (SV) of the bypass path (4a) is opened during the reverse cycle defrost operation, but only from the time at which defrost has already progressed to a certain extent until the completion of defrost. With this arrangement, an excessive reduction of the low pressure and the liquid back-flow are prevented.

摘要： A closed circuit (13) is formed such that the upper ends of preinstalled refrigerant pipes (2A, 2B) in a refrigerant circuit are connected to each other through an upper connecting passage (11) and the lower ends thereof are connected to each other through a lower connecting passage (12). A refrigerant is charged into the closed circuit (13). In a separator (50) of the lower connecting passage (12), a separating heat exchange coil (52) heats the liquid refrigerant to evaporate it, and a filter (53) captures foreign substance from the gas refrigerant. Two conveying heat exchangers (7A, 7B) of the lower connecting passage (12) alternately carry out a repetitive cooling operation of cooling the gas refrigerant, having been changed in phase by the separator (50), to change the phase from gas to liquid and a repetitive pressurizing operation of pressurizing the liquid refrigerant by heating the refrigerant to the extent kept in the liquid phase, respectively, thereby applying a running force to the refrigerant. The refrigerant cleans the preinstalled refrigerant pipes (2A, 2B) in a manner of circulating in the closed circuit (13) from the conveying heat exchangers (7A, 7B).
