Air compressor waste heat recovery system-
Comparison of pressure control methods
Accurate pressure control can not only reduce energy consumption but also improve product quality and reduce waste (thus indirectly energy saving). It can be seen from the figure that in traditional air compressor control, its demand for air pressure is basically unchanged (always at a constant speed) and is adjusted by loading and unloading/control, but in a variable frequency air compressor, it is controlled by speed. To achieve the pressure requirement, its speed can be changed at any time according to the working conditions.

To achieve the pressure requirement, its speed can be changed at any time according to the working conditions.
In traditional air compressors, in order to protect the motor, there are usually regulations on the number of starts and stops. The variable frequency air compressor is completely different. It has soft start and soft stop without current impact, and can basically achieve frequent starts (that is to say, there is no limit on the number of times).
Pressure control = frequency converter + pressure sensor + motor + D control

Energy saving estimation
The loading and unloading of the air compressor is an important part of the operation of the air compressor. Loading time and unloading time are important parameters for air compressor operation. After the frequency conversion transformation, the loading and unloading time of the system is shortened, thereby saving electric energy.
The specifications of your company's existing air compressor are: power , exhaust pressure . (General situation) The general loading rate is about %.
The benefits of using the waste heat recovery device of the oil-free screw air compressor:
The use of boiler hot water requires oil, coal, and electricity, but the waste heat recovery device does not need to be operated cost-free.
, Not affected by climate and weather, as long as our compressor is running, we can provide hot water.
. Low investment cost. After installing the device, there is no need to install other hot water equipment, which immediately helps enterprises and users save money.
, improve the efficiency of the compressor, reduce its operating cost and extend the maintenance cycle and time limit of the machine.
, energy saving and environmental protection.
