Industrial chillers are very common refrigeration equipment for refrigeration. While giving people a good life enjoyment, it also brings great challenges to energy conservation and environmental protection. How to save energy and protect energy? Here is the introduction for everyone.

Method one, the principle of energy saving of chiller: send temperature, reduce condensing temperature, under the premise of meeting equipment safety and production demand, try to increase evaporation temperature and reduce condensation temperature. To this end, the cooling tower has been upgraded to ensure the cooling water efficiency.

Method 2, prevent and reduce pipe fouling to improve the heat exchange efficiency of the condenser and the evaporator. Supplemental water If the water treatment is not done well, the calcium carbonate and magnesium hydrogencarbonate are heated to produce calcium carbonate and magnesium carbonate which are deposited on the pipeline. The thermal conductivity is degraded, affecting the heat exchange efficiency of the condenser and the evaporator, and the electricity cost of the equipment is greatly increased.

At this time, in addition to the water treatment technology, it is also possible to use the pipeline automatic cleaning equipment for pipeline cleaning.

In the third method, the chiller frequency conversion device is used to adjust the rotation 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 running at a non-full load. A fixed-speed centrifuge wastes energy when the equipment is under heavy 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.

Method 4: Adjust the reasonable running load of the chiller equipment. When the equipment is safely operated, the cooling unit operates at 70%-80% load ratio and runs at 100% load, and the power consumption per unit of cooling capacity is smaller. The use of this method to start the pump should be combined with the operation of the pump and cooling tower.
