摘要:
When a guard timer of a compressor (141) expires, an R2 signal from a control section (140) of an outdoor unit is turned on (Action I). If a control section (120) of a freezer unit recognizes from an inside temperature detected by a temperature sensor (124) that the R2 signal is turned on and a request for a shift to a freezer thermo-on state is raised (Action II), a freezer electromagnetic valve (121) is opened (Action III). In general, when the electromagnetic valve (121) is opened, it is supposed that an increase in refrigerant suction pressure is detected by a pressure sensor (146) and then the compressor (141) is actuated. However, if an outside air temperature is low, the refrigerant suction pressure remains lower than a predetermined value. Therefore, the control section (120) actuates a booster compressor (131) (Action IV) to raise the refrigerant suction pressure of the compressor (141).
摘要(中):
当压缩机(141)的保护定时器期满时,来自室外机的控制部(140)的R 2信号被接通(动作I)。 如果冷冻装置的控制部分(120)从由温度传感器(124)检测到的内部温度识别出R 2信号被接通并且提出转换到冷冻热接通状态的请求(动作II ),打开冷冻电磁阀(121)(动作III)。 通常,当电磁阀(121)打开时,假设通过压力传感器(146)检测制冷剂吸入压力的增加,然后压缩机(141)被致动。 然而,如果外部空气温度低,则制冷剂吸入压力保持低于预定值。 因此,控制部(120)启动增压压缩机(131)(动作IV),以提高压缩机141的制冷剂吸入压力。
