Abstract: The invention is a device as well as a system that forms and stores thermal energy in the form of ice and uses the stored thermal energy to provide cooling to residences and other buildings. The device is a refrigerant-based thermal storage system with an ice-tank heat exchanger that cools a refrigerant that is then circulated to an air handler as part of an air conditioning system. The device integrates with commercial heating and cooling devices such as compressors, condensers, air handlers, fans, air conditioning systems, furnaces and heating, ventilation and air conditioning (HVAC) systems.
