The working principle of the air compressor is that a pair of male and female rotors (or called) that mesh with each other rotate in the cylinder, so that the air between the rotor slots continuously generates periodic volume changes, and the air is sucked along the rotor axis. The side is conveyed to the output side to achieve the entire process of suction, compression and exhaust of the air compressor. In the long-term continuous operation process, the air compressor converts electrical energy into mechanical energy, and mechanical energy is converted into wind energy. During the conversion of mechanical energy into wind energy, the air is strongly compressed by high pressure, causing the temperature to rise rapidly. This is a general physics machine. The energy conversion phenomenon, the high-speed rotation of the machine, and the friction heat, the high heat generated by the air compressor oil is mixed into oil, gas and steam are discharged from the body. The heat of the high-temperature oil and gas is equivalent to the input power of the air compressor. 25 to 30%, its temperature is usually 80 ° C (winter) ~ 100 ° C (summer and autumn). Due to the operating temperature requirements of the machine, these heat energy is discharged into the atmosphere as waste heat through the air cooling system of the air compressor.
The air compressor energy-saving system uses the principle of thermal energy conversion to convert the heat recovery from the air compressor into the water. After the water absorbs the heat, the water temperature will rise. The operating temperature of the air compressor unit is reduced, which not only improves the operating efficiency of the air compressor, but also prolongs the service life of the air compressor. The recovered hot water can also be used for hot water bathing in employees, heating in offices and production workshops, boiler replenishing water, Metal coating cleaning treatment, clean room constant temperature and humidity workshop and other places where hot water is needed, thus reducing the long-term payment of operating costs for the welfare hot water and industrial hot water.
The heat recovery system consists of two components: the internal oil circuit of the air compressor; and an external heat exchanger. The heat generated by the air compressor during operation is recovered by the recovery system, and then the hot water is circulated to the heat preservation tank through the circulation pump, and the hot water is taken directly from the water tank through the hot water pump when the hot water is needed. The heat recovery system is a system installed outside the air compressor.
