摘要： A float operated switch (21) is actuated when the level of refrigerant fluid in a reservoir (11) is below a predetermined value to produce an electrical signal. The signal is delayed by 10 to 30 seconds and applied to a switch circuit (54) to disengage an electromagnetic clutch (63) and thereby de-energize a compressor (64). The clutch (63) is also disengaged by the action of a thermal switch (61) when the temperature in a space which is being air conditioned drops below a predetermined value. The operation of the float operated switch (21) is inhibited when the sensed temperature is below the predetermined value and also when a motor which drives the compressor (64) is not operating to prevent erroneous de-energization of the compressor (64).

摘要翻译： 当储存器（11）中的制冷剂流体的水平低于预定值时，浮动操作开关（21）被致动以产生电信号。 信号被延迟10至30秒，并施加到开关电路（54）以使电磁离合器（63）脱离，从而使压缩机（64）断电。 当被空调的空间中的温度下降到预定值以下时，离合器（63）也通过热开关（61）的作用而脱离。 当感测到的温度低于预定值时，以及当驱动压缩机（64）的电动机不工作以防止压缩机（64）的错误断电时，禁止浮动操作开关（21）的操作。
