2. Thermal energy storage SET

During periods of low cooling demand, the cooling equipment operates in overdrive. The surplus energy produced is stored in a SET thermal energy storage unit. The stored cold is then used to meet the cooling load demanded by users. The storage medium can be chilled water, ice or a phase-change eutectic salt.

Thermal energy storage (cold storage/heat storage) can be an interesting strategy for optimizing RFU and RCU. It generally leads to a significant reduction in investment and operating costs, as well as more rational operation of energy production equipment.

2.1 Cold storage design and sizing

The aim is to produce and store refrigeration energy before it is used, for example at night. Two types of technology are available on the...
