Title:
VAPOR COMPRESSION SYSTEMS, EXPANSION DEVICES, FLOW-REGULATING MEMBERS, AND VEHICLES, AND METHODS FOR USING VAPOR COMPRESSION SYSTEMS
Document Type and Number:
WIPO Patent Application WO2004059224
Kind Code:
A8
Abstract:
Flow-regulating members (140) are described that include a primary channel (178) and a plurality of secondary channels (180). The primary channel (178) defines a primary channel orifice (182) in the flow-regulating member (140) and the plurality of secondary channels (180) define a plurality of secondary channel orifices (184) in the flow-regulating member (140). The plurality of secondary channel orifices (184) are located along a common periphery (186) of the flow-regulating member (140), such that an axis passing through the primary channel orifice (182) intersects a plane containing the common periphery (186) at a unique point. At least two of the plurality of secondary channel orifices (184) have different cross-sectional areas. At least one of the plurality of secondary channels (180) intersects the primary channel (178). Expansion devices containing these flow-regulating members (140) are also described, as are vapor compression systems containing expansion devices, and methods of operating vapor compression systems.
