Abstract
A temperature controlling apparatus is provided for use in systems such as a motor vehicle air conditioner. In the temperature controlling apparatus, a cycling clutch and a re-heated air mixing system are selectively used in accordance with the environmental condition. The cycling clutch system temperature control is effected in summer season to control an operating period of time of a compressor, and the re-heated air mixing system temperature control is effected in spring or autumn season to dehumidify the air and in winter season by means of an air mixing door after stopping the compressor thereby controlling an amount of the intake air which is to be re-heated.
