What are the energy-saving methods for chillers?

1. Energy saving principle for industrial chillers: Reduce the condensation temperature while meeting equipment safety and production needs, and try to increase the evaporation temperature and reduce the condensation temperature as much as possible. For this reason, the renovation of the cooling tower has been increased to ensure the efficiency of the cooling water.

2. Prevent and reduce pipeline scaling to improve the heat transfer 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, which will deposit on the pipeline. Reduce the thermal conductivity, affect the heat transfer efficiency of the condenser and evaporator, and significantly increase the operating electricity cost of the equipment. At this time, in addition to using water treatment technology, regular automatic pipeline cleaning equipment can also be used for pipeline cleaning.

3. Adjusting the reasonable operating load of industrial chiller equipment: while ensuring the safe operation of the equipment, the power consumption per unit of cooling capacity is smaller when the refrigeration unit operates at 70% -80% load than when operating at 100% load. When using this method to start up, it is necessary to consider the operation of the water pump and cooling tower comprehensively.

4. Using an industrial chiller frequency conversion device, adjust the speed of the centrifugal chiller (refrigeration machine) 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 devices are operating at non full load. A fixed speed centrifuge causes energy waste during low load operation of the equipment. Variable frequency centrifugal chillers (refrigerators) can automatically adjust the compressor speed according to changes in load, which has a relatively large energy-saving space.
