With the development of science and technology, frequency conversion is widely used in various fields of industrial control due to its advantages of energy saving, high efficiency, noise reduction and reliability. Frequency conversion technology has great potential in the field of energy saving application of cold storage, and can be applied in the transformation of compressor, cold fan, cold storage gate and other equipment.
As is known to all, the compressor system is designed under the condition of maximum refrigerating load in the cold storage, but most of the time the cold storage runs under partial load, and the full opening of the compressor undoubtedly causes energy waste. The application of frequency conversion compressor can effectively solve this problem.The research shows that the performance of the compressor can reach the highest at the rated rate, and the energy saving effect of over 20% can be achieved by using the frequency conversion control of the compressor.
According to the industry online understanding, at present, frequency conversion compressor is mostly used in hvac industry, has not been widely used in cold storage.High initial investment of the project, insufficient short-term energy saving effect to recover additional investment, lack of relevant control strategy and operation and maintenance experience may be the bottleneck that restricts the application of frequency conversion compressor in domestic cold storage.
However, with the development of frequency conversion compressor technology, the improvement of control strategy, the reduction of investment cost and the improvement of user acceptance, the economic advantages of this product will gradually be highlighted, and the application of frequency conversion compressor in cold storage will also have a broad development prospect without doubt.
