Abstract: A method of cooling includes cooling and compressing a refrigerant into a liquid state using a compressor and outside air handler then flowing the refrigerant in the liquid state through heat transfer tubes that are situated within a thermal storage, the thermal storage at least partially filled with a material, where the refrigerant extracts heat from the material as the refrigerant changes state from the liquid into a gas and the refrigerant in gaseous form returns to the compressor. The refrigerant also flows, in the liquid state, into an inside air handler where the refrigerant in liquid form extracts heat from air flowing through the inside air handler as the refrigerant changes into a gaseous state, which then flows back to the compressor where the compressor and outside air handler condenses the refrigerant back into the liquid state.

Abstract: A method of cooling includes cooling and compressing a first refrigerant into a liquid state then flowing the first refrigerant in the liquid state through a first set of heat transfer tubes that are situated within a thermal storage. The thermal storage is at least partially filled with a material. The first refrigerant extracts heat from the material as the first refrigerant changes state from the liquid into a gas and then returns to the compressor. A second refrigerant flows from a second set of heat transfer tubes also situated within the thermal storage and into an inside air handler where the refrigerant in liquid form extracts heat from air flowing through the inside air handler as the second refrigerant changes into a gaseous state. The gaseous second refrigerant then flows back to the second set of heat transfer tubes where temperatures within the thermal storage condense the refrigerant.
