With its advantages of cleanliness, safety and convenient application, compressed air is widely used in all aspects of the industrial field and has become the second largest power source, which is used by almost all manufacturing factories. As the main equipment for producing compressed air, various forms of air compressors are applied to various factories, consuming a lot of energy. As a major energy consumer in the manufacturing industry, air compressors have received more and more attention and have great potential for energy saving.

Heat recovery of air compressors

For the electric-driven air compressor, it can be regarded as an electric heater, because it converts almost all the electrical energy into heat energy in the process of compressing the air, and the generation of these heat energy will affect the normal operation of the air compressor, Therefore, it is necessary to install a good cooling system for the air compressor to ensure the normal and safe operation of the air compressor. Not only is this heat not being used, but additional energy needs to be consumed to help with cooling. If the heat energy recovery of the air compressor is carried out, the comprehensive utilization of energy will be greatly improved.

Frequency conversion transformation of air compressor

At present, many air compressors are in operation, and most of the time is carried out under non-full load conditions, resulting in a waste of power resources. The power of the power frequency air compressor motor is generally large, and the loading and unloading methods are instantaneous, so that the air compressor will have a large starting current when it starts, and a lot of power will be wasted during loading and unloading. The selection of air compressors must meet the maximum gas consumption of the factory, but the actual gas consumption is small and variable. In view of the current phenomenon, the transformation of the frequency conversion control system is urgent.
