Title:
COMPRESSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/198459
Kind Code:
A1
Abstract:
The purpose of the present invention is to efficiently use exhaust heat without affecting the operating efficiency of a compressor. Provided is a compressor system comprising the following: a compressor including a compressor body, a drive source to drive the compressor body, a heat exchanger that exchanges heat with compressed air discharged by the compressor body, and a fan device that generates cooling air that flows to the heat exchanger; and an exhaust passage through which flows exhaust that has exchanged heat with the heat exchanger and that has been scavenged to the outside of the compressor. The exhaust passage branches into at least two passages with a first branched passage being connected to a first space, and a second branched passage being connected to a second space differing from the first space. The compressor system is provided with the following: an exhaust control device that is disposed in at least one of the first branched passage and the second branched passage, and causes cooling air to flow in the exhaust passage; a temperature sensor that detects the temperature of the first space; and a control device that controls the temperature of the compressed air by a fan device so as to be a prescribed temperature, and controls the amount of exhaust passing through the first branched passage by the exhaust control device on the basis of the temperature detected by the temperature sensor.
