    • The disclosed airconditioner has a refrigerant compressor connected to a refrigerant circuit through a four-way valve in each of the room cooling mode and a first room warming mode of operation. The refrigerant circuit has an indoor heat exchanger, an externally heated heat exchanger, a piping, a first electromagnetic valve and an outdoor heat exchanger connected in series. A second electromagnetic valve is connected in parallel to the outdoor heat exchanger between the piping and the four-way valve to form the refrigerant circuit along with the indoor heat exchanger, the externally heated heat exchanger and the piping for the second room warming mode of operation. During the room cooling mode and first room warming mode of operation, the first electromagnetic valve is opened and the piping and the externally heated heat exchanger hold an amount of liquid refrigerant equal to the volume of the outdoor heat exchanger, while in the second room warming mode of operation in which the second electromagnetic valve and an electromagnetic valve connected across the compressor are open the outdoor heat exchange is filled with liquid refrigerant.
    • 所公开的空调机具有在室内冷却模式和第一室内加热方式中的每一个中通过四通阀连接到制冷剂回路的制冷剂压缩机。 制冷剂回路具有串联连接的室内热交换器,外加热换热器,配管,第一电磁阀和室外热交换器。 第二电磁阀与管道和四通阀之间的室外热交换器并联连接,与室内热交换器,外部加热热交换器和第二室内加热方式的管道一起形成制冷剂回路 。 在房间冷却模式和第一室内暖气运转模式下,第一电磁阀打开,管道和外部加热的热交换器保持与室外热交换器的体积相等的液体制冷剂的量,而在第二室内变暖 第二电磁阀和连接在压缩机两端的电磁阀打开室外热交换器的操作模式被液体制冷剂填充。
