<p>PURPOSE:To prevent a load in which its thermostat turns on at first from not being cooled until the rest thermostats of loads are actuated, by restarting a compressor at the detection of any of each temperature detector at a on-temperature or more of the thermostats of each load. CONSTITUTION:Solenoid valves SV1-SV3 at the input of each evaporator, each 1st thermostat which turns off when a temperature of each load is at the lower limit of a prescribed temperature or below and turns on at the prescribed temperature or more, and a timer 30 which is actuated with any turning-off of the thermostats and closes all the magnetic valves after a prescribed time and stops a compressor 5, are provided for a titled device. Further, the 2nd thermostat contacts TH1-TH3 detecting a higher temperature than an on-temperature of the thermostats are provided, and when any of the thermostats detects an abnormal high temperature, the compressor 5 is restarted, allowing to prevent the load in which the 1st thermostat turns on from not being cooled until the 1st thermostats of the rest loads turns on against high temperatures.</p> |
