    摘要： A refrigeration apparatus has a refrigerant circuit which is constituted by a compressor, a condenser, a first pressure reducer, a gas-liquid separator, a second pressure reducer and an evaporator connected to one another in series. The refrigeration apparatus also has a gas injection line connected between a gaseous phase portion of the gas-liquid separator and a compression chamber of the compressor. The improvement comprises a liquid refrigerant extracting passage providing a communication between a portion of the gas-liquid separator at a predetermined level and a portion of the low-pressure side of the refrigerant circuit. With this arrangement, it is possible to stabilize the level of the liquid refrigerant in the gas-liquid separator.

    摘要： A refrigeration system suitable for use in an air conditioner has a main refrigerant circuit including a compressor, a condenser, a first pressure reducer, a gas-liquid separator, a second pressure reducer and an evaporator connected in series to form a closed loop, and a gas injection passage providing a communication between the gaseous phase part of the gas-liquid separator and a compression chamber of the compressor. A stop valve is disposed in the inlet and outlet pipes of the gas-liquid separator, and a bypass passage is provided for connecting directly the outlet pipe of the condenser to the inlet pipe of the evaporator to bypass the gas-liquid separator. The stop valve is adapted to be controlled such that, when the gas injection to the compressor through the gas injection passage is not conducted, the refrigerant flows through the bypass passage bypassing the gas-liquid separator, while the gas-liquid separator functions as a receiver for adjusting the amount of refrigerant circulated in the main refrigerant circuit.

    摘要： An air-conditioner system having a compressor, a plurality of heat exchangers for heating or cooling the air in a room, a radiator for transferring heat energy of refrigerant outside of the room, a plurality of orifices, a manifold with a main port and a plurality of sub-ports, flow direction control multi-port valves directing the flow of the refrigerant from the compressor to the main port and not from the main port to the compressor when at least one of the heat-exchangers is heating the room. The refrigerant does not flow from the compressor to the radiator when at least one of the heat exchangers is heating and none of the heat exchangers is cooling. Also, it does not flow from the compressor to the main port but flows instead from the compressor to the radiator and from the main port to the compressor when none of the heat exchangers is heating and at least one of the heat exchangers is cooling. The system also employs a plurality of valve pairs each of which having a first valve and second valve such that the first valve opens (closes) when the second valve closes (opens). The first valves are arranged for providing flow of refrigerant to the inlet of the compressor from the heat exchangers and the second valves provide flow of refrigerant from the outlet port of the compressor to the respective heat exchanger first ports via the sub-ports of the manifold.

    摘要： A refrigerating apparatus including a refrigerant circuit constituted by a compressor, a condenser, a first expansion device, a gas-liquid separator, a second expansion device and an evaporator which are successively connected. An injection path interconnects an upper part of the gas-liquid separator and a cylinder of the compressor during the compression stroke thereof. An auxiliary path is formed by connecting a solenoid valve closed in the normal operation and an auxiliary expansion device, with the auxiliary path being provided between the gas-liquid separator and the evaporator so as to be parallel to the second expansion device, and connected to the gas-liquid separator at a position higher than the connecting position of the second expansion device to the gas-liquid separator. The solenoid valve is opened when the load on the refrigerating apparatus increases. A main flow path resistance member may be provided in the injection path, and a further path formed by connecting an injection solenoid valve for injection, open during the normal operation and an auxiliary flow path resistance member together with the further path being connected in parallel to the main flow path resistance member. The injection solenoid valve is closed when the load on the refrigerating apparatus increases.

    摘要： A fin-tube type heat exchanger has parallel heat transfer tubes and a stack of a plurality of plate fins mounted on the tubes. Heat exchange is conducted between a first fluid flowing through the tubes and a second fluid flowing through the stack across each of the fins. Each fin has flat tube-mounting portions spaced in the longitudinal direction of the fin and formed with tube-mounting holes and a louver section disposed between each adjacent pair of tube-mounting portions. The louver section has elongated slats extending longitudinally of the fin and having side edges each spaced from an adjacent side edge of an adjacent slat. The slats are classified into two groups in respect of the cross-sectional shape. The slats of one group have generally flat cross-sections to reduce the resistance of the fin to the flow of the second fluid through the stack and are disposed in planes offset from the plane of the tube-mounting portions. The slats of the other group have V-shaped or inverted V-shaped cross-sections to increase stiffness of the fin in the longitudinal direction thereof.

    摘要翻译： 翅片管型热交换器具有平行的传热管和安装在管上的多个板翅片的堆叠。 在流过管的第一流体和跨过每个翅片流过堆叠的第二流体之间进行热交换。 每个翅片具有在翅片的纵向间隔开的扁平管安装部分，并且形成有管安装孔和布置在每个相邻的一对管安装部分之间的百叶窗部分。 百叶窗部分具有从翅片纵向延伸的细长板条，并且具有与相邻板条的相邻侧边缘间隔开的侧边缘。 板条在横截面形状上分为两组。 一组的板条具有大致平坦的横截面，以减小翅片对通过堆叠的第二流体的流动的阻力，并且设置在从管安装部分的平面偏移的平面中。 另一组的板条具有V形或倒V形横截面，以增加翅片在其纵向上的刚度。
