Title:
GAS COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2023/171099
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a gas compressor with which it is possible to adjust the temperature of a heat recovery liquid discharged from an exhaust heat recovery heat exchanger to a desired temperature at low cost without installing a temperature control valve or the like in the path of the heat recovery liquid. To achieve this purpose, a gas compressor comprises a heat exchange liquid temperature sensor 34 that detects the temperature of a heat exchange liquid discharged from an exhaust heat recovery heat exchanger 11, and a path 21 through which at least some of a high-temperature fluid cooled by an air-cooled cooler 20 flows into a compressor body 1, the gas compressor also comprising a heat exchange liquid temperature sensor 34 that detects the temperature Tw2 of a heat exchange liquid discharged from the exhaust heat recovery heat exchanger 11, and a controller 37 having a heat exchange liquid temperature adjustment function for controlling the rotation speed of a cooling fan 30 so that the temperature Tw2 detected by the heat exchange liquid temperature sensor 34 approaches a prescribed target heat exchange liquid temperature Tw2t.
