The air conditioner comprises heat transfer medium temperature adjusting device 1 for adjusting the temperature of a heat transfer medium, an absorption chiller 5 having as a heat source the heat transfer medium supplied from the heat transfer medium temperature adjusting device 1 via a heat transfer medium line 7a through which the heat transfer medium conducts, a valve 9a provided in the heat transfer medium line 7a, a by-pass line 11a branching off from the valve 9a, and an indoor unit 19 supplied with a refrigerant from the absorption chiller 5 or the heat transfer medium from the heat transfer medium temperature adjusting device 1 via the by-pass line 11a. Thereby, at the time of heating, the valve is switched to allow the heat transfer medium to pass through the by-pass line 11, so that the heat transfer medium can be directly supplied via the by-pass line 11 to the indoor unit 19. Hence, in the heating operation, the devices such as pumps involving the operation of the absorption chiller 5 can be stopped, so that the air conditioner can be improved in the energy saving.
