Simulations of Grid-Responsive HVAC Cooling Measures via Ice/PCM storage


This study uses EnergyPlus building energy simulations to assess grid-responsive HVAC cooling measures during peak hours having high electricity prices, including: lock the high capacity of a two-speed cooling coil during grid-response hours; and use ice/PCM energy storage to drive a chilled water coil and meet the cooling load, when shut off the main electric cooling coil. The impacts on peak power reductions, energy and utility cost savings, as well as comfort levels in residential buildings of two U.S. cities, were revealed.
