Abstract
The objective of the present invention is to provide a liquid feed system for a compressor, capable of easily forming fine droplets of a liquid to be injected into the compressor. A liquid feed systemof a compressorfor compressing a gas injects a liquidinto the inside of the compressor. The liquid feed systemadjusts the temperature of the liquidto be injected into the compressorto a temperature at least equal to a saturation temperature Tf corresponding to a pressure inside the compressor, and adjusts the temperature to a temperature lower than a saturation temperature Ti corresponding to a pressure of the liquidat the time of injection into the compressor, and then injects the liquidinto the compressor
