PROBLEM TO BE SOLVED: To adjust an amount or a temperature of obtained hot water without affecting cooling of a compressor, in a system obtaining hot water by heat of compressed air from a compressor.SOLUTION: A heat recovery system includes a first air cooler 8 for cooling compressed air from a compressor 2, a first oil cooler 10 for cooling a lubricant of the compressor 2, and a second air cooler 9 as a heat-recovery heat exchanger. The second air cooler 9 heats water by heat of the compressed air distributed to the first air cooler 8. Water supply to the heat-recovery heat exchanger is controlled on the basis of use load of hot water having passed through the heat-recovery heat exchanger, or the water supply to the heat-recovery heat exchanger is controlled on the basis of a temperature of hot water having passed through the heat-recovery heat exchanger. |
