Abstract: PURPOSE:To reduce an avalability factor of a cooling mechanism without impairing controllability in an air conditioner which has a thermostatic function by making a choice among a successive operation, an interruption and an intermittent operation of the cooling mechanism according to a reserved cooling capacity. CONSTITUTION:In a compressor control routine of a micro-computer 10a of a controller 10, it is checked whether a level that shows a temperature control, a calculated opening Ao of an air mix damper 7 for example, is greater than a reference level A80 corresponding to 80% of a heating capacity or not. If the temperature control level is higher than 80%, a value of a compressor control flag CF is reset to 0. If the level is samller than 80%, it is further checked  whether the level is smaller than 60% or not. When the level is under 60%, the  CF is set to 1 and when the level is over 60%, the CF is changeably set to 1 or  0 in turn in a certain interval. When said CF is set to 1, it energizes an electro- magnetic clutch 31 to run a cooling mechanism and when the CF set to 0, it  stops the mechanism.
