Ice storage air conditioning system principle
The ice storage system is in the low electricity consumption period with low power load, using the preferential electricity price, using the main mechanism ice of the electric refrigeration air conditioner, and storing it in the ice storage equipment; in the daytime when the electric load is high, avoiding the peak electricity price and stopping Or intermittently operate the electric refrigeration and air conditioning main unit to release the cold storage stored in the ice storage equipment to meet the needs of the building air conditioning load.
Developing the background of ice storage air conditioning systems
In order to balance electricity consumption and cut peaks and valleys, countries around the world have fully implemented the peak-to-valley electricity price policy. Under the guidance of the government and the power sector, the government and the power sector have vigorously promoted demand-side management (DSM) to alleviate power construction and Add contradiction in electricity use. Various regions have also introduced relevant policies to promote the development of ice storage air conditioning, which has promoted the development and application of cold storage air conditioning technology. In particular, in recent years, the price difference between peak and valley has been gradually increased, and the price difference between peak and valley in most regions has more than tripled. With the further expansion of the implementation range of peak and valley electricity prices and the increase of the peak-to-valley electricity price ratio, it provides more favorable conditions for the promotion and application of electric energy storage technology.
