Energy Saving and Environmental Protection Methods for Industrial Chillers

Industrial chillers are widely used in modern industrial production, and users are very concerned about whether industrial chillers are energy-saving and environmentally friendly. There are several ways to save energy in the use of industrial chillers:

1. Lower the condensation temperature. On the premise of meeting equipment safety and production requirements, try to increase the evaporation temperature and reduce the condensation temperature. To this end, the transformation of the cooling tower has been increased to ensure the cooling water efficiency.

2. Adjust the reasonable operation of the chiller equipment. Under the condition of ensuring the safe operation of the equipment, the energy consumption per unit of cooling capacity is smaller when the refrigeration host runs at 70~80 load than when it runs at 100 load. Using this method to start the machine should be considered in combination with the operation of the water pump and the cooling tower.

3. Adopt chiller frequency conversion device. Adjust the speed of the centrifugal chiller compressor, and the pressure of the low-pressure refrigerant increases after passing through the centrifuge. The higher the speed of the centrifuge, the higher the pressure rise. In actual operation, most of the equipment is not running at full load. Centrifuges with a fixed rotational speed cause energy waste when the equipment is operated with a small load. The frequency conversion centrifugal chiller can automatically adjust the compressor speed according to the change of the load, and the energy saving space is relatively large.

4. Prevent and reduce the fouling of the pipeline of the bench-type chiller to improve the heat exchange efficiency of the condenser and the evaporator. 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 on the pipeline, which will reduce the thermal conductivity, affect the heat exchange efficiency of the condenser and the evaporator, and greatly increase the electricity bill. rise. At this time, in addition to using water treatment technology, you can also use the regular automatic cleaning equipment for pipeline cleaning.
