Abstract
The invention described herein represents a significant improvement in the efficiency of cooling processes for applications such as buildings, computer equipment, processes, and refrigeration. Described is HVAC energy attached storage whereby an existing HVAC systems cooling capacity is augmented by the addition of a phase changed compressed refrigerant storage and control system. Energy is stored at a first time for subsequent use when electricity is more expensive than a threshold, when electricity availability is constrained, when the thermal load to be cooled is forecasted to be above a threshold, or when a renewable energy source is less available than a threshold.
