    • Upon a selector operation of a valve such as a four-way selector valve provided in a refrigerating cycle for selecting a channel of fluid, prevention of environmental pollution and energy saving and the like are effectively achieved. A sliding valve is coupled with a piston in a housing of a channel selector valve provided in a refrigerating cycle and the sliding valve moves due to a difference in pressure and so on at both sides of the piston, thereby a channel of fluid is selected. A processing section of a control device is constituted with microcomputers of an indoor and outdoor control sections, while a detecting section of the control device includes temperature sensor, detection means for detecting pressure, detection means for detecting flow rate, detection means for detecting voltage/current, and detection means for detecting frequency. Driving sections of an electrically-driven expansion valve, an indoor heat exchanger, an outdoor heat exchanger and a compressor are means that function in response to execution of control programs so that physical quantity, such as pressure, differential pressure and flow rate in the channel selector valve provided in the refrigerating cycle, and a rate of change in physical quantity, such as a rate of change in pressure, a rate of change in differential pressure and a rate of change in flow rate, are controlled, thereby a channel of the fluid is selected by the channel selector valve.
    • 在设置在用于选择流路的冷冻循环中的四通换向阀等阀的选择操作时,有效地实现防止环境污染和节能等。 滑阀与设置在制冷循环中的通道切换阀的壳体中的活塞联接,并且滑阀由于活塞两侧的压力差等而移动,从而选择流体通道。 控制装置的处理部分由室内和室外控制部分的微型计算机组成,而控制装置的检测部分包括温度传感器,用于检测压力的检测装置,检测流量的检测装置,检测电压/ 电流和检测装置,用于检测频率。 电动膨胀阀,室内热交换器,室外热交换器和压缩机的驱动部分是响应于控制程序的执行起作用的装置,使得通道中的物理量例如压力,压差和流量 设置在制冷循环中的选择阀,以及压力变化率,压差变化率和流量变化率等物理量的变化率被控制,由此, 流体由流路切换阀选择。
