Storage source and cascade heat pump systems

A method of adjusting air temperatures in a conditioned space, comprising:

• operating a heating, ventilation, air conditioning, and refrigeration (HVACR) system in one of a heating mode, a heating and cooling mode, or an energy storage mode, or an energy rejection mode, wherein:
• operating in the heating mode comprises:
• operating a thermal system to absorb energy from a storage circuit process fluid of a storage fluid circuit and provide energy to a heating process fluid of a heating circuit, the storage fluid circuit including one or more thermal storage tanks each containing a thermal storage material;
• and
• rejecting energy to the conditioned space at one or more heating coils of the heating circuit, operating in the heating and cooling mode comprises:
• operating the thermal system to absorb energy from the storage circuit process fluid and provide energy to the heating process fluid;
• rejecting energy at the one or more heating coils of the heating circuit, exchanging heat between the storage circuit process fluid and a cooling process fluid of a cooling circuit;
• and
• absorbing energy at one or more cooling coils of the cooling circuit,
• operating in the energy storage mode comprises exchanging heat between the storage circuit process fluid and the cooling process fluid, wherein the cooling process fluid absorbs energy from the conditioned space at the one or more cooling coils and rejects heat to the thermal storage material at the one or more storage tanks, and
• operating a heat pump to absorb energy from a source, and providing the energy absorbed from the source to the one or more thermal storage tanks, and
• operating in the energy rejection mode comprises operating the thermal system to absorb energy from the storage circuit process fluid and reject energy to the heating process fluid, rejecting energy from the heating process fluid to an ambient environment, and the storage circuit process fluid absorbing heat from the thermal storage material at the one or more thermal storage tanks.
