Abstract
An automotive air conditioner has an air duct in which a refrigerant evaporator of a refrigeration cycle is disposed in fluid-flow communication with a variable capacity refrigerant compressor driven by an automotive engine and provided with compressor displacement varying members. A blower is provided to cause air to flow through the evaporator and through the duct into the passenger compartment. A sensor is provided to detect a condition representing the cooling operation of the evaporator, such as the air temperature downstream of the evaporator, surface temperature thereof or the pressure of the refrigerant at the evaporator. An electric controlling circuit is operative in response to signals from the sensor to actuate a servo motor which in turn drives the compressor displacement varying members whereby the capacity of the compressor is varied in accordance with the condition detected by the sensor.
