PURPOSE:To prevent electrical corrosion of a heat exchanger made of aluminum caused by copper ion included in a water droplet from a pipe line when the water droplet generated by bedewing falls onto the heat exchanger from a coolant pipe line of an air conditioner body. CONSTITUTION:An electrolytic corrosion is prevented by a composition consisting of a fixing material 11 executing a fixing of an air conditioner body and a compressor, a heat exchanger 6 made of Al or Al alloy and a cooling cycle unit including a coolant pipe line 7 made of Cu or Cu alloy connected to this heat exchanger 6 to the air conditioner body, by making whole of parts arranged at an upper position of the heat exchanger of the coolant pipe line 7 be composed of a water droplet falling prevention pipe line section 9 inclined to underside toward the coolant pipe line 7 from the heat exchanger 6 and by making the droplet flow downward through the pipe line. |
