How to maximize energy saving of industrial chillers

1. Industrial water chillers prevent and reduce pipeline fouling to improve the heat exchange efficiency of condensers and evaporators. If water treatment is not done well, calcium bicarbonate and magnesium bicarbonate will be heated to produce calcium carbonate and magnesium carbonate and deposit in the pipeline. 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 use of water treatment technology, it is also possible to use regular automatic cleaning equipment for pipeline cleaning.

　　2. Using industrial chiller frequency conversion device to adjust the speed of the centrifugal chiller (refrigerator) compressor. After the low-pressure refrigerant passes through the centrifuge, the pressure increases. The higher the speed of the centrifuge, the higher the pressure rise. In actual operation, most of the equipment is running under full load. A centrifuge with a fixed speed causes a waste of energy when the equipment is running at a small load. The frequency conversion centrifugal chiller (refrigerator) can automatically adjust the speed of the compressor according to the change of the load, and the energy saving space is relatively large.

　　3. Principles of energy saving for industrial chillers: heat generation temperature and reduce condensation temperature. On the premise of meeting equipment safety and production requirements, try to increase the evaporation temperature and reduce the condensation temperature. For this reason, the cooling tower has been modified to ensure the efficiency of cooling water.

　　4. Adjust the reasonable operating load of industrial chiller equipment. Under the condition of ensuring the safe operation of the equipment, when the refrigeration host runs at 70%-80% load than when it runs at 100% load, the power consumption per unit cooling capacity is smaller. Using this method to start up should be combined with the comprehensive consideration of the operation of the water pump and cooling tower.
