Cold Energy Storage System

Cold Energy Storage System is a new type of cold storage energy-saving devices, which makes full use of phase-change energy storage technology to realize user-side peak shaving and valley filling, and completes the “time transfer” of cold energy through the charging and discharging cold cycle of the phase-change material to reduce the cost of refrigeratory electricity under the peak and valley tariff difference dividend.

Core advantages

Optimize the energy efficiency of refrigerator, save energy and reduce carbon emissions

Adjust the operation time of the refrigerator to the night operation with lower ambient temperature, energy efficiency (COP) is improved, carbon emission is reduced, carbon reduction of 5%-28%. Reduce the frequent start and stop of refrigerator, prolong the life of the equipment and reduce the maintenance cost.

Reduced energy costs

Improve the energy efficiency of the chiller, reduce power consumption by 5%-28%, and the proportion of cost saving can reach 30%-63%.

Reduce temperature fluctuations and improve cargo preservation quality

Phase-change materials maintain temperature stability during the cooling and defrosting process, reducing temperature fluctuations and improving the preservation quality of goods.

Operation mode

Cold charging Mode

During valley power or photovoltaic power generation hours, the chiller fully operates , the cold storage module absorbs the cold and the phase- change material freezes.

Cold Release Mode

During non-valley power and non-photovoltaic power generation hours,the phase-change material melts and the cold storage module releases cold to maintain the cold storage at a low temperature, reducing the running time of the chiller and lowering energy consumption.

Frequently Q&A

★What is phase-change material?

When the temperature of a phase-change material increases or decreases to reach the phase change temperature, the physical state changes and the temperature of the material itself remains almost the same un-til the phase-change is completed, while a large amount of latent heat of the phase transition is absorbed or released.

★How to save energy?

Adjust the operation time of refrigeration machine to mainly run at night, the ambient temperature is low, the compressor operates at the optimal working condition, and the energy efficiency (COP) is improved.Flexible adjustment of power hours, mainly in the valley power hours, to avoid or reduce the higher price of electricity in the peak and flat power hours, significantly reducing energy costs.

★Service life?

After laboratory cycle test, the storage module can meet the service life of more than 25 years.

★Does the installation take up the existing

The installation utilizes the existing shelves and is mainly installed in the interlayer of the beams of the shelves, which does not take up additional space. The installation process does not affect the operation of the cold storage, and the subsequent maintenance is convenient.
