Comparing Modes of Operation for Residential Ceiling Fans to Achieve Thermal Destratification 12/15/2014
WHITE PAPER COMPARING MODES OF OPERATION FOR RESIDENTIAL CEILING FANS TO ACHIEVE THERMAL DESTRATIFICATION 12/15/2014 Credit: Thomas Lesser, Research Engineer Jay Fizer, Research-and-Development Laboratory Manager Christian Taber, Applications Engineer Overview Conventional wisdom says to reverse the direction of a ceiling fan’s rotation in the winter. Heat rises, filling a room with warm air from the top down and requiring heaters to run longer to achieve a desired ambient air temperature at the height of the thermostat and occupants. Running a fan in reverse helps move this heat across the ceiling and down the walls, recirculating the warm air through the space. Fans have been capable of reversing direction for decades, and legislation was passed in 2007 that required ceiling fans to have a reverse function. The logic behind reversing a fan is simple: since running fans in the forward direction creates a cooling effect through air movement, reversing those fans helps recirculate heat in the winter without creating an uncomfortable cooling draft. Big Ass Fans is aiming to prove that there’s a more energy-efficient and comfortable way to address heating conservation with ceiling fans. This study compared the effects of paddle fan reversal with Big Ass Fans’ Haiku ceiling fan, operating in the forward direction at lower speed settings than a paddle fan. Hypothesis Primary Hypothesis: Reverse Operation Is Less Efficient Reversing a paddle fan is not the best way to efficiently recirculate heat and fight heat stratification. A Haiku ceiling fan, operating in the forward direction, can destratify a room more efficiently than paddle ceiling fans operating in reverse. -

FFU-HE High Efficiency Fan Filter Unit
FFU-HE High Efficiency Fan Filter Unit Price High-Efficiency Fan Filter Units (FFU-HE) are the most energy efficient line of fan filter units (fan filter modules) on the market today. Designed specifically for use in cleanrooms, pharmacies, pharmaceutical manufacturing facilities and laboratories, the FFU-HE delivers high volumes of HEPA (or ULPA) filtered air at low sound levels while reducing energy consumption by 15 to 50% versus comparable products. Typical Applications Fan Filter Units are used in critical FFU-HE, Roomside FFU-HE, Bench Top Removable Filter Replaceable Filter applications such as healthcare, Ducted Inlet Non-Ducted pharmaceutical compounding, or microelectronics manufacturing. With the integrated HEPA or ULPA filters, ultra-clean air is delivered with a unidirectional vertical downward airflow pattern into the space. The integrated high efficiency motors are designed to overcome the static pressure of the filter, and are ideal for retrofit applications where the FFU-HE Filter Options air handler is not able to provide the required static. Product Information FFU-HE is available in 24x24, 24x36 and 24x48 modules, in both aluminum, stainless steel and hybrid construction. Both PSC and EC motors are available, and have been optimized for industry leading energy efficiency. HEPA filters are typical, while ULPA are available as an option. FEATURES AND OPTIONS High Energy Efficiency • High Energy Efficiency • Industry leading energy efficiency means lower operating costs, potentially saving thousands of dollars in electricity per year. • High Airflow Capacity • Energy consumption as low as 55 Watts at 90 fpm (2x4 module) • Complete Control and • See performance data for specific energy consumptions Monitoring via BACnet High Airflow Capacity • Roomside Removable • High airflow capacity per unit means fewer units and lower first cost (RSR) filter • Active filter area is maximized with the Bench Top Replaceable (BTR) filter, with 2x4 units able to achieve up to 930 CFM. -
Comparison of Computational Results with a Low-G Nitrogen Slosh And
Comparison of Computational Results with a Low-g, Nitrogen Slosh and Boiling Experiment Mark. E. M. Stewart1 VPL at NASA Glenn Research Center, Cleveland, Ohio, 44135 Jeffrey P. Moder2 NASA Glenn Research Center, Cleveland, Ohio, 44135 This paper compares a fluid/thermal simulation, in Fluent, with a low-g, nitrogen slosh and boiling experiment. In 2010, the French Space Agency, CNES, performed cryogenic nitrogen experiments in a low-g aircraft campaign. From one parabolic flight, a low-g interval was simulated that focuses on low-g motion of nitrogen liquid and vapor with significant condensation, evaporation, and boiling. The computational results are compared with high-speed video, pressure data, heat transfer, and temperature data from sensors on the axis of the cylindrically shaped tank. These experimental and computational results compare favorably. The initial temperature stratification is in good agreement, and the two-phase fluid motion is qualitatively captured. Temperature data is matched except that the temperature sensors are unable to capture fast temperature transients when the sensors move from wet to dry (liquid to vapor) operation. Pressure evolution is approximately captured, but condensation and evaporation rate modeling and prediction need further theoretical analysis.
