A cooling system may include a cooling pump that causes cooling fluid received from a thermal load to flow to a cooling source, a low-load valve, a high-load valve, a thermal energy store, and a mixing valve. The cooling source and the low-load valve may be downstream from the cooling pump. The high load valve and thermal energy storage may be downstream from the cooling source. The first input of the mixing valve may be downstream from the thermal energy storage. The second input of the mixing valve may be downstream from the low-load valve and the high-load valve. The thermal load may be downstream from an output of the mixing valve. The cooling system may switch between a low load mode and a high load mode with coordinated operation of the low-load valve and high-load valve.

An auxiliary thermosiphon has an auxiliary refrigerant conduit with an auxiliary evaporation segment in thermally conductive connection to an interior wall of the freezer. The auxiliary refrigerant conduit contains an auxiliary refrigerant that is isolated from the primary refrigerant of the primary cooling apparatus. The auxiliary refrigerant conduit also extends upward to an auxiliary condensation segment of the auxiliary refrigerant conduit at an elevation above the auxiliary evaporation segment. A thermal bridge is in physical thermal contact with the auxiliary condensation segment and in physical thermal contact with a portion of a primary evaporation segment of the primary refrigeration apparatus. Heat is transported through the thermal bridge from the auxiliary thermosiphon to the primary refrigerant conduit and consequently to the primary refrigeration apparatus for removal from the freezer.

According to some embodiments, a floating cold thermal energy storage vessel comprises an ice battery. The ice battery comprises a storage tank configured to store thermal energy in the form of ice and chilled liquid, and a chiller coupled to a refrigerant loop. The refrigerant loop is coupled to the storage tank and operable to transfer thermal energy between the chiller and storage tank to form ice. The ice battery further comprises a heat exchanger coupled to the refrigerant loop, a liquid inlet, and a liquid outlet. The heat exchanger is configured to cool heated liquid received from the liquid inlet and supply cooled liquid to the liquid outlet using the thermal energy stored in the storage tank via the refrigerant loop. According to some embodiments, a regasification and cold thermal energy storage system comprises an ice battery and a liquefied gas regasification system.

A method and system of controlling a temperature includes: controlling circulation of a thermal transfer fluid (TTF) for heat exchange with an interior or exterior of a building independently of heat pump operation; circulating a cold (hot) side TTF for heat exchange with outdoor air during a daytime (night-time); suspending the circulation for heat exchange with outdoor air, when an temperature management application in the building is expected to transfer enough heat to eliminate need of the circulation. A system (and a module for storage and control) for thermal energy storage and management for a building includes a heat pump, hot side and cold side PCM tanks, hot side and cold side TTF circuits to exchange heat with an inside or outside environment of the building by circulating each TTF, and a controller, where the circulation of both TTFs is configured independent of operation of the heat pump. The system allows serves as thermal battery for renewable energy or for grid power allowing decoupling of thermal energy utilization, the outdoor heat rejection/harvesting and the compressor's operation.
