Abstract
A waste-heat recovery system includes a compressor main body; a gas piping, a waste-heat-recovery heat exchanger, a circulation circuit, and a tank with a water inlet piping and a water outlet piping that stores water that exchanges heat with the heat medium by connecting to the circulation circuit. The waste-heat recovery system also includes an inlet valve, a circulation pump, and a gas temperature sensor that detects the temperature of the compressed gas by arranging in the gas piping. The waste-heat recovery system also includes a water temperature sensor that detects the temperature of the water in the tank, and a control device that controls the inlet valve and the outlet valve according to detection temperature of the gas temperature sensor and the water temperature sensor.
