Abstract
A cooled air temperature detector detects the temperature of air that has just passed through a refrigerant evaporator. The detector detects air temperatures for a plurality of locations on the cooling unit. When determining a control condition (ON/OFF condition) of the refrigerant compressor based on the post-evaporator temperature, an air conditioner ECU calculates and compares respective air temperatures detected by the detector and processes the lowest air temperature as the post-evaporator temperature. In another embodiment, a sensor detects a surface temperature at a plurality of locations on the refrigerant evaporator. The operation of the refrigerant compressor is controlled based on the lowest surface temperature detected.
