Patent application: Air-conditioning system

Ben Welter - Friday, April 19, 2019

U.S. patent application 20190113259 (applicant Ford Global Technologies LLC, Dearborn, Mich.):

"An air-conditioning system includes first and second PCM vessels, a heat recovery circuit, and a conduit and valve system. The heat recover circuit includes a third PCM vessel. The conduit and valve system operably couples i.) a first heat exchanger to the first PCM vessel and a radiator, ii.) a second heat exchanger to a core and the second PCM vessel, and iii.) the heat recovery circuit to the first heat exchanger."

Patent application: Reflective temperature modulating blanket

Ben Welter - Thursday, April 11, 2019

U.S. patent application 20190106878 (inventor Robert Joe Alderman, Poteet, Texas):

"A temperature modulating blanket utilizing a reflective surface to block radiation away from a phase change material [110] during daylight and in thermal conductivity with the material to allow heat conduction out of the material at night at a faster rate than it is absorbed during the daylight. The reflective surface is uniquely tailored to both serve a reflective function during daylight while also being sufficiently thermally conductive to facilitate the heat conduction as indicated during night. Additionally, the facilities may be uniquely configured to promote an attic circulation that further facilitates freezing and recharge of the phase change material of the blanket during night hours."
