Abstract:
1. An air conditioner by comprising: an exhaust heat recovery unit for recovering exhaust heat in a heat transfer medium; a heat transfer medium passage in which said heat transfer medium outputted from said exhaust heat recovery unit flows; an auxiliary heating device, provided in said heat transfer medium passage, for heating said heat transfer medium; an absorption chiller, to which said heat transfer medium passage is connected, to be driven by heat of said heat transfer medium; a refrigerant passage, through which a refrigerant outputted from said absorption chiller flows; an indoor unit to which said refrigerant is supplied through said refrigerant passage; a heat transfer medium temperature detecting means for detecting a temperature of said heat transfer medium flowing through said heat transfer medium passage; a refrigerant temperature detecting means for detecting a temperature of said refrigerant flowing through said refrigerant passage; and a control portion for controlling an operation of driving said auxiliary heating device, wherein on startup, said control portion controls an operation of driving said auxiliary heating device according to the temperature of said heat transfer medium on startup, which is detected by said heat transfer medium temperature detecting means, wherein when the temperature of said refrigerant, which is detected by said refrigerant temperature detecting means, is equal to or lower than a predetermined temperature, said control portion decides that a startup operation is completed, and wherein upon completion of the startup operation, said control portion controls an operation of driving said auxiliary heating device according to the temperature of said refrigerant, which is detected by said refrigerant temperature detecting means.
