Now advocate energy conservation and environmental protection. So how can industrial chillers save energy? What are the ways to save energy?

1. Reduce the condensing temperature Under the premise of meeting equipment safety and production requirements, try to increase the evaporation temperature and reduce the condensing temperature. For this reason, the cooling tower is modified to ensure the cooling water efficiency;

2. The chiller frequency conversion device is used to adjust the speed of the centrifugal chiller compressor. After the low pressure refrigerant passes through the centrifuge, the pressure rises. The higher the speed of the centrifuge, the higher the pressure rises. In actual operation, most of the equipment is operated at a non-full load;

3. Adjust the reasonable running load of the chiller equipment. When the equipment is safely operated, the cooling main engine runs at 70%-80% load ratio and runs at 100% load. The power consumption per unit of cooling capacity is smaller. It is necessary to combine the operation of the water pump and the cooling tower into consideration;

4, to prevent and reduce pipe fouling to improve the heat transfer efficiency of the condenser and evaporator. Supplemental water If the water treatment is not good, calcium carbonate and magnesium carbonate heated by calcium bicarbonate and magnesium bicarbonate will deposit on the pipeline. Decreasing the thermal conductivity, affecting the heat exchange efficiency of the condenser and the evaporator, and greatly increasing the electricity cost of the equipment.
