How much higher is the energy efficiency of a variable frequency chiller than general refrigeration equipment?
Variable frequency chillers are usually more efficient in terms of energy efficiency ratio than traditional fixed rate chillers. Generally speaking, it is common for the energy efficiency ratio of variable frequency chillers to be about 20% to 30% higher than that of traditional fixed rate chillers. This improvement is mainly due to the application of variable frequency technology, which can intelligently adjust the operating speed of the compressor according to the actual load demand, thereby reducing energy consumption and improving refrigeration efficiency.
This improved energy efficiency ratio makes the variable frequency chiller more energy-efficient and efficient in actual operation, which can reduce energy consumption and operating costs. Therefore, when choosing refrigeration equipment, it is very important to consider the energy efficiency ratio, especially for application scenarios with long-term operation and high power demand. Choosing a variable frequency chiller with a high energy efficiency ratio can bring obvious energy saving effects.
