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.

A temperature control apparatus for use in a motor vehicle air conditioner, the temperature control apparatus comprising: an evaporator means; a heater core means for re-heating air cooled by said evaporator means; a compressor means for circulating a refrigerant through said evaporator means; an air mixing means for controlling a ratio of an amount of cooled air passing through said heater core means for re-heating to an amount of cooled air bypassing said heater core means; a first temperature controlling circuit means for controlling a position of said air mixing means to maintain a temperature of a vehicle chamber at a desired level and for stopping said compressor means immediately prior to said evaporator means being frozen; and a second temperature controlling circuit means for controlling an operating period of time of said compressor means to maintain the vehicle chamber temperature at said desired level; and means for selectively switching said first and second temperature controlling circuit means in dependence upon operating conditions of said air conditioner.
