Abstract

The present invention relates to a method of controlling an air conditioner actuating a compressor through driving force of an engine and operated with heating or cooling air, the method including the steps of: determining whether the engine is running (S10); comparing the ambient temperature and the set temperature when the engine is running in step S10 (S20); determining whether an auxiliary heat source is required by comparing the cooling water temperature with the set temperature of a waste heat recovery device which recovers waste heat generated in the engine through cooling water and circulates the waste heat when the ambient temperature is lower than the set temperature in step S20 (S30); comparing an engine load and a set load when it is determined that the auxiliary heat source is required in step S30 (S40); generating a delay adjustment signal for adjusting an ignition timing of the engine according to the set load after step S40 (S50); and applying the delay adjustment signal generated in step S50 to the engine and generating additional waste heat in the engine (S60), wherein a refrigerant that has passed through an evaporator is exchanged with the cooling water of the waste heat recovery device. According to the present invention, the ignition timing of the engine is intentionally delayed to generate additional waste heat upon operation in a cold environment with low ambient temperature, and the generated waste heat is provided to the refrigerant passing through a plate-shape heat exchanger, so that heating performance is improved.
