Can cold thermal energy storage be integrated with a solar refrigeration system?
The integration of cold thermal energy storage with a solar refrigeration system (SRS) will be the next-generation alternative for battery-based backup, which has the potential to run the system at low cost and net-zero carbon emission-based F&V storage. CTES is classified into latent and sensible heat-based energy storage.
What is the purpose of a refrigeration storage system?
The main purpose of the storage is to provide the peak cooling demand during the cooling down of new products when they are placed in the cooler (pull-down load) so that the refrigeration system can be sized for the average refrigeration load rather than the peak load.
What is cold energy storage?
Cold energy storage is possible by changing the phase (latent heat storage) or the temperature of storage (Sensible heat storage) medium. Based on the method of energy storage, CTESS is categorized into latent heat cold energy storage (LHCESS) and a Sensitive heat energy storage system (SHESS).
What is a cold storage unit?
Cold storage unit consists of a solar panel system of 7 KW maximum output. It supplies the energy to run the refrigeration system during the sun time hours. Surplus energy is stored in batteries to run the system continuously for backup period of 18 h.
