    摘要： The air conditioner includes a first and a second heat exchanger, a plurality of compressors, a pipe for uniform distribution of oil, a plurality of oil separators, and an oil return opening. The first heat exchanger performs heat exchange between air of an indoor space and refrigerant to condition the air. The second heat exchanger is connected to the first heat exchanger through a pipe, to perform heat exchange between the refrigerant and water. The plurality of compressors is installed at one side of the second heat exchanger, to compress the refrigerant to a high temperature and a high pressure. The pipe for uniform distribution of oil communicates the plurality of compressors with each other, to guide a flow of oil within the plurality of compressors to flow between the compressors. Each oil separator is provided at an outlet of a respective compressor, to separate oil included in refrigerant discharged from the compressors. The oil return opening guides the oil separated by each of the oil separators to flow into all or any one of the plurality of compressors.

    摘要： An oil separate and collect device (1) has a horizontally elongated container body (2) disposed in a horizontal orientation. A gas inlet (3), through which compressed gas containing oil flows into the container body (2), is located at an upper part on one end side of an interior of the container body (2). A gas outlet (4), through which the compressed gas from which oil has been separated flows out of the container body (2), is located at an upper part on the other end side of the interior of the container body (2). A partition board (5) divides a lower part of the interior of the container body (2) into a first chamber (6) on a gas inlet (3) side and a second chamber (7) on a gas outlet (4) side.

    摘要： The present disclosure relates to a refrigerating cycle apparatus and a method for operating the same. For a refrigerating cycle having a plurality of compressors connected in series for multi-stage compression, an inner space of each compressor and a pipe of the refrigerating cycle are connected via an oil collection pipe (42, 46), and oil is induced to be discharged into the refrigerating cycle by pressure reversal during pressuring balancing, so as to allow the discharged oil to be collected into a high-stage compressor (12) or a low-stage compressor (11). Accordingly, an amount of oil can be uniformly maintained in each of the plurality of compressors to prevent in advance a frictional loss of the compressors or an increase in power consumption caused due to a lack of oil, and also a device and pipes for solving oil unbalancing between the compressors can be simplified to enhance cooling efficiency of the compressors.
