The lubricating oil of the air compressor generates a large amount of excess heat during operation, and this waste heat needs to be cooled by radiators and cooling fans to ensure the normal operation of the air compressor. This cooling method not only causes high operating costs, but also discharges hot air into the atmosphere, which is not conducive to environmental protection. The recycling system is designed to convert most of the heat into warm water or hot water for recycling without any negative impact on the performance of the compressor. Provide employees with domestic hot water, industrial water, hot water air conditioning, etc. for the enterprise. This reduces the long-term economic costs incurred by enterprises for heating hot water. The air compressor heat recovery system consists of a heat exchanger, a proportional valve, a temperature sensor, and an electronic control part.
