    Abstract: Disclosed is a refrigeration system including a heat transfer fluid circulation loop configured to allow a refrigerant to circulate through the circulation loop. A purge gas outlet is in operable communication with the heat transfer fluid circulation loop. The system also includes at least one gas permeable membrane having a first side in operable communication with the purge gas outlet and a second side. The membrane includes a separation layer including a porous inorganic material with pores of a size to allow passage of contaminants through the membrane and restrict passage of the through the membrane, and a polymer coating over the separation layer. A permeate outlet is in operable communication with the second side of the membrane.

    Abstract: An HVAC&R system that includes a first pumping device configured to circulate a first volume of a first two-phase medium, a second pumping device configured to circulate a second volume of the first two-phase medium, a first plurality of secondary HVAC&R units, a second plurality of secondary HVAC&R units, a first primary HVAC&R unit, and a second primary HVAC&R unit. At least one of the first plurality of secondary HVAC&R units is operably coupled to the first pumping device. At least one of the second plurality of secondary HVAC&R units is operably coupled to the second pumping device. The first primary HVAC&R unit is operably coupled to at least one of the first plurality of secondary HVAC&R units and the first pumping device. The second primary HVAC&R unit is operably coupled to at least one of the second plurality of secondary HVAC&R units and the second pumping device.

    Abstract: A moisture removal system for removing moisture from a gas is disclosed including a water absorption vessel with a microemulsion. The system also includes a gas-liquid phase separator in fluid communication with a water absorption vessel gas outlet, a gas outlet for conditioned air in fluid communication with a conditioned space, and a liquid outlet. An optional heat exchanger heats used microemulsion from the water absorption for water desorption in a water desorption vessel. An optional microemulsion regenerator provides thermal regeneration of microemulsion from the water desorption vessel for returning regenerated microemulsion to the water absorption vessel.

    Abstract: An ejector has: a motive flow inlet (40); a secondary flow inlet (42); an outlet (44); a motive flow nozzle (242) having an outlet (110); a primary flowpath from the motive flow inlet through the motive flow nozzle to the ejector outlet; a secondary flowpath from the secondary flow inlet to the ejector outlet, merging with the primary flowpath at the motive nozzle outlet; a control needle (200; 300; 400) shiftable along a range of motion between a first condition and a second condition and seated against the motive nozzle in the second condition. The needle comprises: a main shaft (210); a tip (204); a first portion (220; 320) converging toward the tip; and a shoulder portion (214; 314; 422) between the first portion and the main shaft and seated against the motive nozzle in the second condition and converging toward the tip at a greater angle (?1; ?1 2) than an angle (?2; ?2 2) of the first portion.
