    • An air conditioning system comprises an outdoor unit and a plurality of indoor units, a plurality of delivery conduits for supplying working fluid from a variable capacity energy source located in the outdoor unit to the indoor units, and a plurality of control valves respectively provided in the delivery conduits. A temperature sensor and a reference temperature setting device are provided for each room for transmitting corresponding temperature data to a central control unit. The central control unit detects whether the sensed temperature of each room is increasing or decreasing as a function of time and whether the sensed temperature is above or below a predetermined temperature associated with a value established by the reference setting device. Based upon these data the central control unit provides a control signal for closing the valve to divert a certain amount of the total supply energy to other rooms. Another control signal is generated to increase the total amount of supply energy when the temperature level and its gradient of each room indicate a shortage of the total supply energy and to decrease the total amount when a total energy supply excess is indicated.

    • The compression capacity of a rotary compressor may be changed by a cylinder bypass system. The change of compression capacity is achieved by a slide wall member which composes part of an inside wall of a cylinder containing a compression mechanism and which is movable, thereby bypassing gas being compressed to a suction side of the compressor. The slide wall member is caused to slide forward by gas pressure applied and to slide backward by a spring force. By controlling such gas pressure, the capacity of the compressor may be changed. A relatively large opening is formed in the cylinder when the slide wall member is moved backward, so that the compression capacity can be greatly reduced without a large decrease in efficiency.
    • 旋转式压缩机的压缩容量可以通过气缸旁通系统来改变。 压缩容量的变化通过构成包含压缩机构的缸体的内壁的一部分并且可移动的滑动壁构件来实现,从而将被压缩的气体旁路到压缩机的吸入侧。 滑动壁构件被施加的气体压力向前滑动并且通过弹簧力向后滑动。 通过控制这种气体压力,可以改变压缩机的容量。 当滑动壁构件向后移动时,在气缸中形成相对较大的开口,从而可以大大降低压缩容量,而不会大大降低效率。
