<p>In an air conditioner, a cooling water circuit (40) includes a first passage for returning the cooling water passing through the engine (30) to the engine (30), a second passage for supplying the refrigerant heating heat exchanger with the cooling water that is branched from the first passage and passes through the engine, and an electrically-driven three-way valve (41) for sharing the cooling water to the first passage and the second passage, and a controller sets a cooling water target temperature so that the cooling water target temperature is variable in accordance with at least one of an outside air temperature and the temperature of a room to be air-conditioned under heating operation, and controls the electrically-driven three-way valve (41) so that the cooling water flowing in the second passage is increased when the cooling water temperature is higher than the cooling water target temperature.</p> |
