Abstract: A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a heating fluid circuit, a cooling fluid circuit, and a storage fluid circuit. A thermal system of the HVACR system absorbs energy from the storage fluid circuit and rejects it to the heating fluid circuit. The storage fluid circuit includes thermal storage tanks containing thermal storage material that can provide energy for heating or absorb energy for cooling depending on the state of the thermal storage material. Heating can be provided using the heating fluid circuit and the heat provided by the thermal system. Cooling can be provided using the cooling fluid circuit by absorbing energy from the conditioned space using a cooling fluid and rejecting energy from the cooling fluid to the storage fluid circuit. The thermal storage tanks can have heat added to them using an air source heat pump system to support heating operations.

Abstract: Heat exchangers for thermal storage systems include a valve that can direct process fluid passing through the heat exchanger through supplemental heat exchanger tubing based on a temperature of the process fluid. The supplemental heat exchanger tubing can be located in areas where ice formation can occur during freezing of the storage fluid of the thermal storage system, but apart from the standard flow path for the heat exchanger. The valve can be a thermally-actuated valve. The thermally actuated valve can be set to divert flow of the process fluid to the supplemental tubing when the process fluid is at or above a melting temperature of the storage fluid. Methods can include selectively flowing process fluid through supplemental heat exchange tubing when it is at a temperature greater than the melting point of a storage material.
