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.
How much energy does a cold storage facility use?
After personnel, energy is usually their second highest operating expense. Cold storage facilities consume an average of 25 kWh of electricity and 9,200 Btu of natural gas per square foot per year, with refrigeration accounting for more than 70 percent of overall electric usage.
Do control strategies affect cooling capacity & energy consumption of cold storage facilities?
In order to explore the effect of different control strategies on the cooling capacity, energy consumption and electricity bill of cold storage facilities, a specific cold storage facility was used as an example, and an energy consumption prediction method was established based on a transient thermal model.
Why do refrigeration systems use a lot of energy?
It is commonly observed that refrigeration systems are responsible for a large amount of electric energy consumption in many industrial plants, which are mainly due to compressor operation. Energy demands in European food industry have been growing at a rate of 1.8 % per year .
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.
