Abstract: [0068] A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system includes a first condenser configured to place a first refrigerant in a heat exchange relationship with a cooling fluid, a second condenser configured to place a second refrigerant in a heat exchange relationship with the cooling fluid, and a conduit system configured to direct a first portion of the cooling fluid from a cooling fluid supply to the first condenser and then through a first section of the second condenser in a series configuration. Further, the conduit system is configured to direct a second portion of the cooling fluid directly from the cooling fluid supply to a second section of the second condenser, such that the first portion of the cooling fluid and the second portion of the cooling fluid flow through the first condenser and the second condenser in a parallel configuration.

Abstract: A spray system includes a spray applicator (12) configured to apply a fluid to a target. The spray system also includes a rotary bell cup (44) of the spray applicator (12), a splash plate (42) of the spray applicator (12) coupled to the rotary bell cup (44), and a fluid tip (40) of the spray applicator (40). The fluid tip (40) is configured to output the fluid onto the rotary bell cup (44). The fluid tip (40) includes a fluid tip passage (39) extending along a longitudinal fluid tip axis (72) of the fluid tip (40). The longitudinal fluid tip axis (72) intersects with the splash plate (42) of the spray applicator (12). The fluid tip (40) also includes a fluid exit port (75) configured to output the fluid from the fluid tip passage (39) onto the rotary bell cup (44). The fluid exit port (75) extends along a fluid exit axis (76) disposed at an angle relative to the longitudinal fluid tip axis (72) of the fluid tip (40).

Abstract: The present disclosure relates to a purge system for a vapor compression system, where the purge system includes an emission canister configured to receive a gas flow. The gas flow includes a mixture of non-condensable gases and refrigerant of the vapor compression system. An adsorbent material is disposed within the emission canister and configured to adsorb the refrigerant and enable the non-condensable gases to flow toward an exhaust of the emission canister, where the adsorbent material is a silica gel.

Abstract: A compressor includes an impeller, a diffuser passage having a diffuser vane therein, and a variable geometry diffuser ring positioned between the impeller and the diffuser vane with respect to a flow of a refrigerant through the compressor. The compressor also includes an actuator configured to move the variable geometry diffuser ring in a direction transverse to the flow of the refrigerant, and between a plurality of ring positions including a fully retracted ring position in which the variable geometry diffuser ring does not block the flow of the refrigerant, and at least one protruded ring position in which the variable geometry diffuser ring adjusts an angle of the flow of the refrigerant upstream of the diffuser vane.
