Patent number: 11131467Abstract: An HVAC system is described having components of a variable refrigerant flow (VRF) outdoor compressor unit connected to an indoor fan coil unit. The indoor fan coil unit supplies air to ducts that condition a plurality of zones. Each zone has a volume modulating air damper that can maintain a predetermined volume of air flowing through it. As the dampers for some zones vary between open and close positions, the air pressure in the ducts changes. The volume modulating dampers compensate for these pressure changes, ensuring that only the predetermine volume of air is passing into the zones. By regulating the volume of into each zone, the volume modulating air dampers can restrict the air volume through the fan coil causing the outdoor unit to reduce compressor speed, thereby saving energy.Type: GrantFiled: December 13, 2019Date of Patent: September 28, 2021Inventors: Gene Osheroff, Jeff Osheroff

Patent number: 10982907Abstract: A heat pipe includes one or more reservoirs of liquid that are closed at lower temperatures and open at higher temperatures. The opening of the reservoirs at higher temperatures caused by higher power levels dynamically increases the amount of liquid in the heat pipe, which increases performance of the heat pipe at higher power levels. As the heat pipe cools, the liquid condenses and flows back into the reservoirs. As the heat pipe continues to cool, the reservoirs close. The result is a heat pipe that is more efficient at lower power levels and still maintains high efficiency at higher power levels due to the demand-based charging of the liquid based on temperature.Type: GrantFiled: November 14, 2017Date of Patent: April 20, 2021Assignee: International Business Machines CorporationInventors: William J. Anderl, Bret P. Elison, Phillip V. Mann, Arvind K. Sinha
