Abstract

A technique is provided that can prevent damage to a waste heat recovery heat exchanger. An air compressor includes cooling heat exchangers that perform heat exchange between cooling water and compressed air, and a cooling liquid pipe through which the cooling water flows. A waste heat recovery unit includes waste heat recovery heat exchangers that perform heat exchange between waste heat recovery water and compressed air, a waste heat recovery liquid pipe through which the waste heat recovery water flows, a waste heat recovery liquid inlet pipe and a waste heat recovery liquid outlet pipe that connect an auxiliary cooling facility and the waste heat recovery liquid pipe, flow path switching three-way valves that open and close the inlet and outlet pipes, and a temperature controller that controls the valves. When the temperature of the waste heat recovery water exceeds a threshold, the temperature controller opens the inlet and outlet pipes by controlling the three-way valves.
