Abstract:
The purpose of the present invention is: to enable hot water at a required temperature to be supplied, even in cases when compressor load factor is low; to suppress heat dissipation from a waste-heat recovery device; and to improve waste-heat recovery rate. A waste-heat recovery system in an oil-cooled gas compressor is provided with: a compressor main body ( 3 ); an oil separator ( 6 ); gas piping ( 8 ) which supplies, to a demanded destination compressed gas separated from oil by the oil separator; oil piping ( 7 ) which returns, to the compressor main body, the oil separated by the oil separator; and a waste-heat-recovery heat exchanger ( 10 ) which recovers heat from the compressed gas and/or the oil. The waste-heat recovery system is also provided with: a hot-water storage tank ( 19 ); circulation circuits ( 17, 18 ) in which a heat medium is made to circulate between the waste-heat recovery heat exchanger and the hot-water storage tank; a circulation pump ( 22 ) provided to these circulation circuits; and a control device ( 32 ) which, in cases when the temperature of the oil or the compressed gas subjected to heat exchange in the waste-heat-recovery heat exchanger is equal to or less than the temperature of the hot water in the hot-water storage tank, stops the circulation pump or reduces the rotational frequency of the circulation pump.

Claim (Index 5):
The waste-heat recovery system in the oil-cooled gas compressor according to  claim 3 , comprising at least any of:\n a delivery temperature sensor for detecting a temperature on a delivery side of the compressor main body; an oil temperature sensor for detecting the temperature of the oil on an outlet side of the waste-heat-recovery heat exchanger; and a gas temperature sensor for detecting the temperature of the compressed gas on the outlet side of the waste-heat-recovery heat exchanger; wherein the circulation pump is stopped or the rotational frequency thereof is reduced in a case where the temperature detected by at least any of the delivery temperature sensor, the oil temperature sensor, and the gas temperature sensor is equal to or lower than the temperature detected by either of the hot water temperature sensor or the heat medium temperature sensor.
