PURPOSE:To enable dehumidification and air conditioning even at a low temperature in the open air by providing a switching device of sorting out only a signal of the set temperature which changes in linkage with a thermostat lever to maintain the set value in the proximity of the maximum cooling output signal. CONSTITUTION:The output line 17a of a rheostat 17 comes in short circuit with the earth line 20a of a thermo amplifier 20, when a switch 30 is turned on by operating a switch button. As a result, the output of the rheostat 17 is set at the output value of the maximum cooling; namely, R1 being in the state of 0. Then, a compressor is run to blow warm air free of moisture, no matter where a temperature regulating lever is between COLD and HOT, because a relay energizing signal is outputted from the thermal amplifier 20 independently of the set temperature and the temperature at the outlet port of an evaporator. Thus, dehumidification and air conditioning become available even at a low temperature in the open air. |
