Railcar Backup Cooling System
A railcar backup cooling system may be added to an existing railcar (e.g., a boxcar) to provide supplemental or backup cooling to the railcar in the event that an HVAC failure or other circumstance occurs, which causes the interior temperature of the railcar to rise. The system includes a container of liquid or compressed gas mounted on the railcar, a valve controlling the flow of the liquid or gas from the container, and a controller configured to open the valve when the HVAC system fails or is otherwise unable to maintain the railcar at the desired temperature. When the valve is opened, the liquid and/or gas stored in the container may exit, expanding into a cool gas and thereby acting to cool the railcar environment.
Method for thermal energy storage and management for building and module and 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.

SELF-SUSTAINABLE MULTIPLE-TANK COOLER WITH ENERGY STORAGE AND CHAMBER FOR TEMPERATURE COMPENSATION
Cooler composed by an outer tank, within which a cooling tank and a useful tank are housed, among which there is an array of thermal energy accumulators, and within the tank useful there are temperature compensation chambers.
System and method of mode-based compressor speed control for refrigerated vehicle compartment
A system is provided that includes mode, shore power, engine, and battery modules. The mode module determines whether to operate in a shore power, engine, or battery mode based on parameters. The shore power module, while in the shore power mode, runs a compressor at a speed based on a temperature within a container of a vehicle and limits the speed to a first speed. A battery is charged based on utility power while in the shore power mode. The engine module, while in the engine mode, limits the compressor speed to a second speed. The battery, while in the engine mode, is charged based on power received from an alternator/generator. The battery module, while in the battery mode, limits the compressor speed to a third speed. While in the battery mode, the battery is not being charged based on power from a shore power source and the alternator/generator.
METHOD FOR REDUCING CONDENSER SIZE AND POWER ON A HEAT REJECTION SYSTEM
A heat transfer system for high transient heat loads includes a fluid, a heat exchanger; a compressor downstream of the heat exchanger outlet; a condenser downstream of the compressor outlet, and a thermal energy storage (TES) section downstream of the condenser outlet and upstream of the heat exchanger. The TES section may include a first pressure regulating valve downstream of a TES unit; and a second pressure regulating valve upstream of the first pressure regulating valve.
