PROBLEM TO BE SOLVED: To make it possible to prevent hot water from overflowing from a drain pan even if a control valve fails to operate (the valve is not closed). SOLUTION: An air conditioner, which supplies heating hot water from a heat source machine to a water supply machine 58 by way of a control valve 57 and drops the hot water to a heat exchanger 40 by way of the water supply machine 58, comprises a drain pan which receives the hot water dropped to the heat exchanger 40, a water level detector which detects the water level of the hot water received in the drain pan and a means which forcibly stops the operation of the heat source machine when the water level detector operates. |
