    Abstract: A cooling system that may include a source of liquid natural refrigerant, a heat exchanger in communication with the source of liquid natural refrigerant that is configured to convert the liquid natural refrigerant into a gaseous natural refrigerant, a compressor in communication with the heat exchanger and configured to increase a temperature and pressure of the gaseous natural refrigerant received from the heat exchanger, and an exhaust device in communication with the compressor and configured to expel the gaseous natural refrigerant received from the compressor to air of an external ambient environment. The exhaust device includes a membrane that permits the gaseous natural refrigerant to exit the exhaust device while preventing or at least minimizing the air of the external ambient environment from entering the exhaust device.

    Abstract: A climate-control system may include a vapor-compression circuit and an air handler assembly. The vapor-compression circuit may include a compressor, an outdoor heat exchanger, and first and second working-fluid-fluid flow paths. The first and second working-fluid-flow paths are in fluid communication with the outdoor heat exchanger. The first working-fluid-flow path may include a first expansion device and a first indoor heat exchanger. The second working-fluid-flow path may include a second expansion device and a second indoor heat exchanger. The first and second indoor heat exchangers are disposed within the air handler assembly. The air handler assembly includes a return-air-inlet duct, first and second airflow paths, and a supply-air-outlet duct. The first airflow path may receive air from the return-air-inlet duct and houses the first indoor heat exchanger. The second airflow path may receive air from the return-air-inlet duct. The supply-air-outlet duct receives air from the first and second airflow paths.

    Abstract: A condenser charge module is configured to: determine a first amount of refrigerant in each condenser of one or more condensers of a refrigeration system; determine a total condenser amount of refrigerant based on the one or more first amounts. An evaporator charge module is configured to: determine a second amount of refrigerant in each evaporator of two or more evaporators of the refrigeration system; and determine a total evaporator amount of refrigerant based on the two or more second amounts. A line charge module is configured to: determine a third amount of refrigerant in each refrigerant line of multiple refrigerant lines of the refrigeration system; and determine a total line amount of refrigerant based on the multiple third amounts. A total module is configured to determine a total amount of refrigerant in the refrigeration system based on the total condenser, the total evaporator, and the total line amounts.

    Abstract: An example refrigeration system includes an indoor fluid loop, an outdoor fluid loop, and a heat exchanger assembly. The indoor fluid loop circulates a first working fluid. The outdoor fluid loop circulates a second working fluid that is different from the first working fluid and is separated from the indoor fluid loop by a wall of a structure. The heat exchanger assembly is mounted within the wall of the structure. The heat exchanger assembly includes a heat exchanger and a housing, where the heat exchanger is disposed within an internal space defined by the housing. The housing supports the heat exchanger within the internal space and is mounted to a structure of the wall.

    Abstract: A refrigeration system includes: a leak sensor disposed within a building and configured to measure an amount of refrigerant that has leaked from the refrigeration system within the building; a prediction module configured to determine a predicted amount of refrigerant that has leaked from the refrigeration system within the building based on the measured amount; and a leak module configured to: determine whether a leak is present in the refrigeration system within the building based on the predicted amount of refrigerant that has leaked from the refrigeration system; and take one or more remedial actions when a leak is present in the refrigeration system within the building.

    Abstract: A heat-pump system may include an outdoor heat exchanger, an expansion device, an indoor heat exchanger, a compressor, and a multiway valve. The expansion device is in fluid communication with the outdoor heat exchanger. The indoor heat exchanger is in fluid communication with the expansion device. The compressor circulates working fluid through the indoor and outdoor heat exchangers. The multiway valve may be movable between a first position corresponding to a cooling mode of the heat-pump system and a second position corresponding to a heating mode of the heat-pump system. The working fluid flows in the same direction through the outdoor heat exchanger in the cooling mode and in the heating mode, and the working fluid flows in the same direction through the indoor heat exchanger in the cooling mode and in the heating mode.
