Patent number: 9610825Abstract: A vehicle climate control system includes a thermal-adsorption heat pump driven by engine exhaust heat, the heat pump including two adsorbers asynchronously switching between adsorbing and desorbing modes, each adsorber coupled with a corresponding antifreeze tank via a plurality of refrigerant-containing wick chambers. Cold heat transfer fluid (HTF) flows through the adsorber during the adsorbing mode which causes evaporation of refrigerant from the wick chambers, thereby cooling antifreeze, whereas hot HTF flows through the adsorber during the desorbing mode which causes condensation of refrigerant at the wick chambers, thereby heating antifreeze. In this way, the thermal-adsorption heat pump may condition cabin air independent of engine coolant and without exerting a load on the engine.Type: GrantFiled: April 6, 2015Date of Patent: April 4, 2017Assignee: Ford Global Technologies, LLCInventors: Yongfang Zhong, Michael Levin, Furqan Zafar Shaikh, Danrich Henry Demitroff, Donald Masch

Publication number: 20150273974Abstract: 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: ApplicationFiled: March 25, 2014Publication date: October 1, 2015Applicant: Ford Global Technologies, LLCInventors: Michael Levin, Furqan Zafar Shaikh, Danrich Henry Demitroff, Lawrence Marshall
