Packaged Unit Air Conditioning Thermal Energy Storage Module Theoretical Energy Efficiency PerformanProject Number ET 06.10 Organization SCE End-use HVAC Sector Commercial Project Year(s) 2006 - 2006
Manufacturers of energy storage modules (ESMs) claim that their systems, in addition to providing load shifting capabilities, can also deliver energy savings to end-users. While previous studies have shown that, given the right set of circumstances, an ESM system can be used for demand shifting from high demand periods to lower demand periods, no independent studies have been conducted to evaluate the claims of energy efficiency. The objective of the project is to identify any energy savings potential of this type of system. The approach will be to perform a theoretical “high-level” energy performance analysis of an ESM System versus a standard air-cooled package unit (PU) in a small commercial facility located within several climate areas in the SCE service territory.
