Because different regions and industries have different habits, there are many titles for the industrial chiller industry, such as industrial chillers, industrial refrigeration systems, etc. are relatively common, and this article mainly introduces the energy saving of industrial chillers. method. Specifically divided into four steps, starting from four aspects, including expounding the energy-saving principles of industrial chillers, preventing and reducing pipe fouling to improve the heat exchange efficiency of condensers and evaporators; adjusting the reasonable operating load of chiller equipment; The specific method is explained in full detail using the frequency conversion device of the chiller, etc. The details of each aspect are as follows.

1. The principle of energy saving of industrial chillers: reduce the condensing temperature. On the premise of meeting equipment safety and production requirements, try to increase the evaporating temperature and reduce the condensing temperature. To this end, the transformation of the cooling tower has been increased to ensure the cooling water efficiency.
2. Prevent and reduce pipe fouling to improve the heat exchange efficiency of the condenser and evaporator: make up water, if the water treatment is not done well, the calcium carbonate and magnesium carbonate produced by the heating of calcium bicarbonate and magnesium bicarbonate will be deposited in the pipe On. The thermal conductivity is reduced, the heat exchange efficiency of the condenser and the evaporator is affected, and the electricity cost of the equipment operation is greatly increased. At this time, in addition to the water treatment technology, you can also use the regular automatic cleaning equipment for pipe cleaning.
3. Adjust the reasonable operating load of the chiller equipment: Under the condition of ensuring the safe operation of the equipment, the power consumption per unit cooling capacity is smaller when the cooling host runs at 69%-82% load than when it is running at the load. Combined with the operation of the water pump and cooling tower, it is considered comprehensively.
4. The chiller frequency conversion device is used to adjust the speed of the centrifugal refrigerator compressor. After the low-pressure refrigerant passes through the centrifuge, the pressure rises. The greater the speed of the centrifuge, the higher the pressure. In actual operation, most of the equipment is in Non-full-load operation. The centrifuge with a fixed speed will waste energy when the equipment is running at a small load. The variable-frequency centrifugal chiller can automatically adjust the compressor speed according to the change of the load, and the energy saving space is relatively large.
