Patent number: 9920846Abstract: Methods and systems are provided for regulating fluid flow through a three-way valve assembly, including a three-way split conduit coupled to a movable rotary ring with plurality of openings. In one example, a three-way split conduit may include one fluid inlet conduit splitting into two outlet conduits with an included angle of less than 90 degrees between the two splitting outlet conduits. A movable rotary ring coupled to the three-way split conduit may be rotated by an actuator to open or block the three way split conduits, regulating the fluid flow passages along the three-way valve assembly.Type: GrantFiled: November 10, 2015Date of Patent: March 20, 2018Assignee: Ford Global Technologies, LLCInventors: Danrich Henry Demitroff, Cary Cole, Sunil Katragadda, Lawrence Marshall, Furqan Shaikh Zafar

Patent number: 9789746Abstract: An air-conditioning system which may be included in a motor vehicle may include a single pair of tube-and-plate heat exchangers arranged within a common vacuum enclosure, the heat exchangers selectively coupled with a heat source, a radiator, and an air-conditioning core. During an adsorbing/evaporating mode, coolant may circulate between a first heat exchanger and the radiator and vapor may evaporate from the surface of non-adsorbent-coated plates of the second heat exchanger and be adsorbed at adsorbent-coated plates of the first heat exchanger while coolant circulates between the second heat exchanger and the core. During a desorbing/condensing mode, coolant may circulate between a heat source and the first heat exchanger to effect desorption of vapor from the adsorbent in the first heat exchanger, while melting PCM in the core exchanges heat with air blown through the core to provide cooling.Type: GrantFiled: March 25, 2014Date of Patent: October 17, 2017Assignee: Ford Global Technologies, LLCInventors: Michael Levin, Furqan Zafar Shaikh, Danrich Henry Demitroff, Lawrence Marshall
