As a common energy equipment, air compressors play an important role in industrial production. However, during the operation of the air compressor, a large amount of waste heat will be generated. If this waste heat cannot be effectively utilized, it will lead to energy waste. In order to improve energy utilization efficiency, air compressor waste heat recovery units have emerged.
Working principle of air compressor waste heat recovery unit
Air compressor waste heat generation: During the operation of the air compressor, the compressor compresses the air, causing an increase in air temperature and generating a large amount of heat, which is the waste heat of the air compressor.
Waste heat recovery process: Heat exchanger: The waste heat recovery unit of the air compressor conducts the waste heat from the air to the recovery medium (such as water or oil) through the heat exchanger.
Heat transfer process: Through the heat transfer process, the temperature in the recovered medium is raised, and then the recovered medium with this raised temperature is used for heating water, heating, or other situations that require thermal energy.
System cycle: The waste heat recovery system of the air compressor forms a circulating heat energy system, continuously converting the generated waste heat into usable heat energy, thereby achieving energy reuse.
Application scenarios of waste heat recovery units for air compressors
Industrial production: used for heating industrial water, heating boiler water, etc., to improve production efficiency. Utilize waste heat for refrigeration, used to cool machine equipment or products.
Commercial buildings: Heating systems used to heat commercial buildings, providing a comfortable indoor environment. Used for hot water supply in commercial buildings, such as hotels, swimming pools, and other places.
Agricultural greenhouse: used for heating agricultural greenhouses and improving the growth environment of crops inside the greenhouse.
Other fields: Combining heat pump systems to improve the thermal efficiency of the system.
Energy recovery: used in energy recovery systems to improve the energy utilization efficiency of the system.
