Refrigeration capacity design of energy storage container

Should energy storage be integrated in refrigerated warehouses?

This work evaluated the potential benefits of integrating energy storage in the refrigerated warehouses. Two types of energy storage systems have been considered, including a cold energy storage system and an electrical energy storage system.

What types of energy storage systems are available for refrigerated warehouses?

For refrigerated warehouses, two types of energy storage systems can be selected: the cold energy storage system and the electrical energy storage system. Cold energy storage systems have been widely used in buildings.

What is the heat transfer area & cooling capacity of a refrigerated system?

The heat transfer area and cooling capacity of each unit are 275m2 and 40kW, respectively. A controller is used to control the operation of the refrigerated system. The refrigerated system and fans stop when the indoor temperature is below -2oC and start when the indoor temperature reaches 5oC.

Can a cold energy storage system achieve zero electricity consumption?

However, the cold energy storage system cannot achieve zero electricity consumption during the daytime, since fans and pumps still need to operate. When the electrical energy storage system is used instead of the cold energy system, the operation strategy is simpler.

How does a cold energy storage system work?

Energy storage systems For the cold energy storage system, it is assumed that the refrigerated system works at full capacity during the hours, in which the electricity price is low (from 23:00 to 7:00). In addition to provide the required cooling during this period, the extra cold energy is stored for the use during the rest of day.

Can energy modelers model refrigeration systems?

Energy modelers should be aware that modeling of refrigeration systems is not standard. Many commercially available programs do not have the ability to accurately model refrigeration systems. If a simulation program cannot model the system, exceptional calculation methodology per LEED requirements shall be used.
