New energy-saving ideas: Creative approaches to improving the COP of chiller units through energy savings

Thread Content

The chiller unit accounts for 60% of the energy consumption in an entire air conditioning system; therefore, improving its energy efficiency can lead to significant savings in energy use. One of the metrics used to indicate the energy consumption of a chiller unit is COP, so increasing this COP value is the most effective way to reduce energy consumption. The COP is closely related to the temperatures of both the chilled water and the cooling water. Therefore, improving the heat exchange efficiency of the evaporator and condenser helps to increase the COP. At the same time, enhancing the lubrication of the compressor is also important, as lubrication has a significant impact on energy consumption; otherwise, manufacturers would not produce magnetic levitation compressors. By improving lubrication and thus heat exchange efficiency, it is possible to increase the COP. We have implemented projects involving 3 million tons of cooling capacity, and have gained extensive experience in improving the COP. On the refrigerant side, we use refrigeration oil additives imported from the United States to enhance lubricity, remove accumulated oil films and carbon deposits, thereby raising the temperature of the chilled water. On the water side, physical water treatment equipment is employed; this, in combination with chemical water treatment, increases the heat transfer capacity of the condenser, thus helping to improve the COP. We are very willing to make our own contribution to energy conservation and consumption reduction in China.
