ABSTRACT:
A variable thermostat-type air conditioning system for an automotive vehicle passenger compartment has a dehumidification switch. When a driver depresses the dehumidification switch the compressor begins to operate as if the temperature-adjusting lever were set to the extreme COOL end. Therefore, it is possible to dehumidify or cool the passenger compartment without adjusting the temperature-adjusting lever which is already set to an appropriate lever position. The air-conditioning system according to the present invention comprises a temperature-sensitive element, a variable resistor linked to the temperature-adjusting lever, the dehumidification switch to short the variable resistor, and a thermocontrol amplifier, in addition to a standard compressor, evaporator, etc.
