6 FAQs about [Refrigeration system energy storage method]
Can cold thermal energy storage improve cooling system reliability and performance?
The integration of cold energy storage in cooling system is an effective approach to improve the system reliability and performance. This review provides an overview and recent advances of the cold thermal energy storage (CTES) in refrigeration cooling systems and discusses the operation control for system optimization.
When is thermal energy storage implemented?
Thermal energy storage is implemented in the refrigeration system during off-peak periods (nights and weekends). During peak hours, a part of the thermal load is covered by the storage and the rest is covered by the refrigeration system.
What is the purpose of a refrigeration system?
The purpose of a refrigeration system in cold thermal energy storage is to remove heat from a medium and reject this heat to the ambient. For instance, in a refrigerator at home, we want to keep the air and products inside cold to prevent them from spoiling.
What is generated refrigerating energy?
In this context the heat removed from a cooled system is referred to as “generated refrigerating energy” QoN. It results from the integration of the refrigerating capacity over the time period Dt = t2 t1. The input energy is technical work Wt to drive the whole system
How can cold storage improve the reliability of a refrigeration system?
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.
What is a cold storage system?
For a general cold storage system, the basic structure is divided into a refrigeration unit and a cold storage tank, as well as other ancillary structures. The primary objective is to convert electrical energy into cooling capacity, thereby generating cold.
