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 10):
The waste-heat recovery system in the oil-cooled gas compressor according to  claim 1 , comprising:\n an air cooling heat exchanger provided on a downstream side of the waste-heat-recovery heat exchanger for cooling the compressed gas flowing through the gas piping and a lubricant flowing through the oil piping; and a cooling fan for blowing a cooling wind to the air cooling heat exchanger; wherein the rotational frequency of the cooling fan is controlled such that the temperature of the compressed gas delivered from the compressor main body falls in a prescribed range.
