What Are The Energy Saving Methods for Chillers?
Adjust the reasonable operating load of the 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. The use of this method to start up should be combined with the operation of the water pump and cooling tower for comprehensive consideration.
The frequency conversion device of the chiller is used to adjust the speed of the compressor of the centrifugal chiller. 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 non-full load. The centrifuge with a fixed speed will cause energy waste when the equipment is small and suitable for operation. The frequency conversion centrifugal chiller can automatically adjust the speed of the compressor according to the changes in the load, and the energy saving space is relatively large.
The principle of energy saving for chillers: control temperature and reduce condensing temperature. On the premise of meeting equipment safety and production requirements, try to increase the evaporating temperature and reduce the condensing temperature. For this reason, the cooling tower has been modified to ensure the energy efficiency of the cooling water.
Prevent and reduce pipeline fouling to improve the heat exchange efficiency of the condenser and evaporator to supplement water. If the water treatment is not done well, calcium bicarbonate and magnesium carbonate will be deposited on the pipeline. The thermal conductivity is reduced, the heat exchange efficiency of the condenser and the evaporator is affected, and the electricity cost for the operation of the equipment 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 cleani
