Because different regions and industries have different habits, there are more titles for the industrial refrigerator industry. For example, industrial chiller , industrial ice chiller , etc. are more common, and this article mainly introduces industrial refrigerator and chiller The energy-saving method is divided into four steps, including four aspects, including elaborating the energy-saving principles of industrial refrigerators, preventing and reducing pipe fouling to improve the heat transfer efficiency of condensers and evaporators; adjusting refrigerators. Reasonable operating load of the equipment; adopting a full range of detailed methods such as frequency converters for refrigerators, etc. The details of each aspect are as follows
I. Energy-saving principle of industrial refrigerators: send temperature, reduce condensation temperature On the premise of meeting equipment safety and production requirements, increase the evaporation temperature and reduce the condensation temperature as much as possible. To this end, the transformation of the cooling tower has been increased to ensure the cooling water efficiency.
Second, prevent and reduce pipeline fouling to improve the heat transfer efficiency of the condenser and evaporator: If the water is not treated well, the calcium carbonate and magnesium carbonate produced by the heating of calcium bicarbonate and magnesium bicarbonate will be deposited on the pipeline . The heat conduction performance is reduced, the heat exchange efficiency of the condenser and the evaporator is affected, and the equipment operation electricity cost is greatly increased. In addition to using water treatment technology at this time, you can also use regular automatic cleaning equipment for pipeline cleaning.
Third, adjust the reasonable operating load of the refrigerator: Under the condition of ensuring the safe operation of the equipment, the cooling host runs at a load of 69% -82% than when it runs at 100%, the power consumption per unit of cooling is smaller. Using this method to start up should be considered in conjunction with the operation of the pump and cooling tower.
Fourth, the frequency conversion device of the refrigerator is used to adjust the speed of the centrifugal refrigerator compressor, and the low-pressure refrigerant passes through the centrifuge, and the pressure rises. The higher the speed of the centrifuge, the higher the pressure rises. In actual operation, most of the equipment runs at non-full load. Centrifuges with fixed speeds cause energy waste when the equipment is operating at low loads. The variable frequency centrifugal refrigerator can automatically adjust the speed of the compressor according to the change of the load, and the energy saving space is relatively large.
It is very important to master the energy-saving methods of industrial refrigerators, because this is an important step to enhance product competitiveness and achieve win-win with customers. Dongguan Guansheng Machinery Co., Ltd. has also continuously improved its superior products in plastic auxiliary machines.
