A liquid reservoir, a method for manufacturing the liquid reservoir, and a compressor having the liquid reservoir are disclosed. The liquid reservoir has a barrel, an air inlet tube, an air outlet tube, and a valve. The valve has a partition plate arranged in the barrel. An outer periphery of the partition plate is coupled to an inner peripheral wall of the barrel to divide the internal space of the barrel into an air inlet chamber and an air outlet chamber. The partition plate has a valve hole communicating the air inlet chamber with the air outlet chamber. A limit plate is arranged in the air outlet chamber and at least partially spaced apart from the partition plate. An outer periphery of the limit plate is coupled to the inner peripheral wall of the barrel. The limit plate has a connection hole and a guide hole.

A refrigeration system includes a vapor compression loop and a purge system in communication with the vapor compression loop. The purge system includes a separator including for separating contaminants from a purge gas provided from the vapor compression loop to the separator and a movement mechanism operable to increase a pressure of the purge gas. The pressure of the purge gas drives the purge gas through the separator.

A cooling system for an industrial facility includes a facility that has a thermal energy output and an input, a dry cooler that includes a plurality of blowers, an evaporative cooling tower, a fluid-cooled chiller, a valving system that receives a thermally-charged media from the thermal energy output for delivery to at least one of the dry cooler, the evaporative cooling tower, and the fluid-cooled chiller, and a temperature sensor that is in communication with the valving system via a controller. The temperature sensor measures a current ambient temperature and cooperates with the controller to automatically adjust the valving system to direct the thermally-charged media to one of the dry cooler, the evaporative cooling tower, and the fluid-cooled chiller for rejecting heat from the thermally-charged media to define a thermally-receptive media. The cooling system further includes a return conduit that delivers the thermally-receptive media to the input.

A thermal management system includes an open circuit refrigeration circuit that has a refrigerant fluid flow path, with the refrigerant fluid flow path including a receiver configured to store a refrigerant fluid, a first control device configured to receive refrigerant from the receiver, a liquid separator, and an evaporator configured to extract heat from a heat load that contacts the evaporator, with the evaporator coupled to the first control device and the liquid separator. The system includes a pump having an inlet and an outlet, with the outlet of the pump coupled to the liquid side outlet of the liquid separator and a second control device that is coupled to an exhaust line, that is coupled to the vapor side outlet of the liquid separator through the second control device. In operation, the evaporator in the open circuit refrigeration circuit would be coupled to a heat load.

A gas-side stop valve on the gas refrigerant side and a liquid-side stop valve on the liquid refrigerant side are provided in a package of an outdoor unit. A gas-side filter on the gas refrigerant side is mounted on the indoor unit side relative to the gas-side stop valve and inside the package of the outdoor unit. A liquid-side filter 9 on the liquid refrigerant side is mounted on the indoor unit side relative to the liquid-side stop valve and inside the package of the outdoor unit. As a result, it is not necessary to ensure a place for mounting the gas-side filter and the liquid-side filter at the time of installation on site and the workability can be improved.

An oil separator has a filter portion in a differential pressure generation mechanism configured to collect, by a differential pressure, lubricating oil that is in a form of mist included in high-pressure refrigerant that flows in a first pipe that is connected to a discharge port of a compressor and allows the collected lubricating oil to move downstream along an internal wall of the first pipe.

A filter-drier unit for a refrigerant includes an exterior housing formed of a hard material, and a desiccant material supported within the exterior housing and being formed of a metal-organic framework material having inorganic metal ions and bridging ligands that link the metal ions. The metal-organic framework has a three-dimensional permanently porous structure that has at least one chemically tunable characteristic, such as pore size, pore volume, and surface area.

Heat exchanger (1) for a refrigerant fluid loop, the heat exchanger (1) comprising at least one outlet (6) configured to allow a refrigerant fluid (100) to exit the heat exchanger (1), the heat exchanger comprising a core (34) and a tank (7), that comprises said outlet (6), and the heat exchanger (1) comprising at least one filter (2), characterized in that the filter is adapted to filter (2) the refrigerant fluid (100) that exits the tank (7) and in that said filter (2) is flat. The present invention proposes various arrangements in order to integrate the filter (2) within the heat exchanger (1), including and not limited to the attachment of a connection block (3), housing the filter (2), to the heat exchanger (1).

A bidirectional filter drier has a generally spherical outer shell having a first opening and a second opening. The shell contains a desiccant core and first and second filter elements. The first filter element is on a first side of the core, adjacent the first opening, and the filter flexible element on a second side of the core adjacent the second opening. The first filter element and the second filter element control flow around and through the core depending on the direction of fluid flow through the filter drier.
