Considerations for energy-saving design of air compressor systems

The air compressor system must be energy-efficient. When selecting equipment, selecting station locations, and designing pipeline installations, the following matters should be noted to ensure that the system meets the energy-efficient operation conditions.

The location of the air compressor station should be well ventilated, less dusty, and clean. If conditions permit, a location with low humidity should be selected.

The energy saving of the compressor head of the air compressor belongs to the professional field and is generally difficult to compare. If economic conditions permit, it is better to choose a frequency converter. The less moisture content in the compressed air, the smaller the heat load of the rear cooling equipment, and the lower the energy consumption of the system operation. Therefore, the air compressor needs to have its own dehumidification equipment, such as a water vapor separator, to separate and discharge the moisture in the air in time. In addition, the lower the outlet temperature, the easier it is to separate the moisture in the compressed air. If there is a built-in heat exchange device in the air, it can effectively reduce the outlet temperature of the air compressor and may effectively reduce the operating energy consumption. Compared with some air compressors, the exhaust temperature cannot be too low before the oil and gas separation, otherwise the oil and water will mix, which will directly affect the service life of the air compressor oil and even cause equipment failure.

Energy-saving precautions for compressed air system pipeline installation design. The pipeline connection adopts flange connection, which is easier to disassemble and install, reduces pollution, and reduces the energy consumption of system operation. The pipeline installation should have a certain inclination, and the drain pipe and automatic drain valve device should be installed at a low position to drain the moisture in the pipeline in time, reduce the water content of compressed air, and have a certain energy-saving effect. The pipeline from the air compressor to the drying equipment should be designed to be larger. If the air compressor outlet air collection main pipeline is equipped with air-water separation equipment, the outlet air moisture can be separated and discharged in time, which is conducive to the energy-saving operation of the system. The main pipeline between each air separation equipment includes the gas storage tank, which is designed as a double pipeline system that can be switched. In the branch pipe of the main pipeline, it should be noted that the branch pipe should be connected from the opening directly above the main pipeline.
