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.
Investigating a real-scale supermarket refrigeration system at a laboratory level is costly and a complex procedure compared to refrigerated display cabinets and vending machines, although all-in-one CO2 refrigeration system for supermarkets is explored by Pardiñas et al. , considering an integrated ice storage into the display cabinets.
Key benefits of integrating CTES into commercial refrigeration systems are the possibility to shift energy purchases to low-cost periods by using the storage to achieve peak shaving of the refrigeration demand. Consequently, the power consumption stabilisation through the day will be achieved .
Last but not least, the cold storage can increase the system reliability by supplying the cooling capacity under different unforeseen conditions such as a power blackout situation or component failure in the refrigeration system. There are three strategies to operate a CTES that is integrated into a refrigeration system.
Many real-life applications, such as industrial process plants and AC systems, require significant storage capacities to achieve peak shaving. Hence, experimental characterisation of larger lab-scale and prototype CTES units is a key factor to raise the attention on the application of cold storage into these refrigeration systems.
