Fig. 1 shows all the equations for the proposed PHS model. This model first calculates Q p during the pump mode. Next, ∀ is calculated. Finally, P t is calculated during the turbine mode. The operating mode of this model can be controlled by adjusting P m and T v.In practice, P m can be controlled by a variable speed drive, and T v is the percent …

Thermal energy storage is like an "HVAC battery" for a building''s air-conditioning system. Trane Thermal Energy Storage systems use standard cooling equipment, plus an energy storage tank to shift all or a portion of a building''s cooling needs to off-peak, night time hours. Model C energy storage tanks store energy in the form of ice during off-peak …
