Methods and structures are disclosed to dispense a liquefied gas solution from a liquefied gas solution (LGE) container. The LGE container comprises a temperature sensor to detect the temperature of the liquefied gas solution within the LGE container. The LGE container temperature is controlled using a temperature control element and a processor connected to the temperature sensor and to the temperature control element. The LGE is transferred from the container into a secondary container through a valve. The method includes the following steps: (a) opening the valve to allow the LGE to flow from the LGE container into the secondary container; (b) taking readings from the temperature sensor; and (c) based on the temperature readings, heating the LGE container to maintain the temperature of the LGE container at a predetermined temperature or within a predetermined temperature range.

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

Embodiments of the present disclosure relate generally to systems and methods for controlling the temperature of inflatable evacuation systems. Specific examples provide a system that heats at least one portion of an inflation system of the evacuation system in order to regulate the temperature of the inflation gas.

Systems and methods for controlling the temperature and pressure of a cryogenic liquid methane storage unit are provided. The disclosed systems and methods generate methane gas from a reservoir of liquid methane stored within the methane storage unit, vent the methane gas through one or more outlet valves connected to the methane storage unit, and generate electric power using the vented methane gas. The generated electric power can then be used to initiating a cooling cycle, which reduces the temperature of said reservoir of liquid methane and reduces the pressure in said methane storage unit. Micro anaerobic digesters and methane storage units may be configured in a networked environment with a central controller that monitors remote units.
