What is Air Compressor waste heat recovery? The waste heat recovery of the Air Compressor is a new type of effective waste heat utilization equipment. It heats the cold water by absorbing the waste heat of the Air Compressor without energy consumption. This equipment is mainly used to deal with employees' lives and industrial hot water, etc. Problems, saving energy consumption for enterprises, thus saving a lot of costs. This article mainly introduces waste heat recovery systems of several typical Air Compressors, such as oil-injected screw Air Compressors, oil-free screw Air Compressors, centrifugal Air Compressors, etc. The analysis of the characteristics of the waste heat recovery system, these rich methods and forms of waste heat recovery of Air Compressors, provide reference for relevant units and engineering and technical personnel, so as to better carry out waste heat recovery work, thereby reducing energy costs of enterprises and reducing environmental impact. Thermal pollution, to achieve the purpose of energy saving and environmental protection.
