    • An air-conditioning apparatus includes a body casing of an indoor unit formed in a substantially rectangular parallelepiped shape. The body casing is formed with a body inlet port on a body bottom, and a body outlet port is formed in each body side. The body casing houses a centrifugal fan, a fan motor rotatably driving the centrifugal fan, and an indoor heat exchanger disposed so as to surround an outer periphery of the centrifugal fan in planar view. In each of the body outlet port, a joint is protrudingly provided with a body-side duct connecting portion that connects a duct thereto. Further, outlet ports are formed. The air-conditioning apparatus includes a plurality of outlet units each protrudingly provided with an outlet-side duct connecting portion that connects the duct thereto. Furthermore, at least one of the joints is formed with a plurality of the body-side duct connecting portions.
    • 一种空调装置,其特征在于,具备形成为大致长方体的室内机的主体壳体。 主体壳体在主体底部形成有主体入口,并且在每个主体侧形成主体出口。 主体壳体容纳离心风扇,可旋转地驱动离心风扇的风扇马达,以及在平面图中围绕离心式风扇的外周配置的室内热交换器。 在本体出口的每一个中,接头突出地设置有将导管连接到其的主体侧管道连接部。 此外,形成出口。 空调装置包括多个出口单元,每个出口单元突出地设置有将管道连接到其的出口侧管道连接部分。 此外,至少一个接头形成有多个主体侧管道连接部。

    • The present invention provides a refrigeration cycle apparatus using a first compressor and a second compressor driven by an expander and including a high and low pressure heat exchanger, in which a low-pressure-side outlet of the high and low pressure heat exchanger is bypassed to a low pressure portion or an intermediate pressure portion to adjust an inlet density at the expander and thereby provide high efficiency. The high and low pressure heat exchanger of the refrigeration cycle apparatus of the present invention changes an amount of heat exchange between a high-pressure refrigerant and a reduced-pressure refrigerant branched from the high-pressure refrigerant at an inlet portion of the high and low pressure heat exchanger and reduced in pressure to adjust the density of the refrigerant flowing in the expander so that power recovered by the expander and power required by the second compressor match.
    • 本发明提供了一种使用第一压缩机和第二压缩机的制冷循环装置,所述第一压缩机和第二压缩机由膨胀机驱动,并且包括高压和低压热交换器,其中高压和低压热交换器的低压侧出口旁通至 低压部分或中压部分,以调节膨胀机处的入口密度,从而提供高效率。 本发明的制冷循环装置的高低压热交换器使高压制冷剂与在高低压入口部分从高压制冷剂分支的减压制冷剂之间的热交换量变化 压缩热交换器,并且降低压力以调节在膨胀器中流动的制冷剂的密度,使得由膨胀器回收的功率和第二压缩机所需的功率匹配。
