heat wheel

heat wheel

[′hēt ‚wēl]
(mechanical engineering)
In a ventilating system, a device to condition incoming air by causing it to approach thermal equilibrium with the exiting air; hot incoming air is cooled, and cold incoming air is warmed.

One of the market's unique functions is its Fresh Air Handling Unit (FAHU) and Air Handling Unit (AHU), which recovers between 30 and 40 per cent of energy through its speed motors and heat wheel energy recovery system.
Fortunately this can generally be supplied in cold weather with heat wheel operation alone.
While there are other types of heat-recovery techniques, the use of the desiccant-coated heat wheel is the most efficient option for most applications unless cross contamination of air is a critical issue.
Key features include a heat wheel that permits installation of 30% more heating capacity for heavy PET preforms used to make refillable or hot-fillable bottles.
It is built with the largest installation of energy-efficient heat wheel technology in the U.
The heat wheel rotates through the two air streams and transfers the energy from the air being exhausted from the building to the incoming airstream.
The correlation for the axial heat conduction effect on the heat wheel effectiveness is
Substituting Equations 52 and 57 into Equation 58, the effectiveness for a counterflow regenerative heat wheel exchanger with Cr = 1 and [f.
The film, 2 years in the making, provides an insider's perspective of the sport, following the Miami Heat Wheels on their underdog quest to rise to the top ranks of the league.
And in BAS software, rooftop units may only show the fans spinning, while QA Graphics' images include animations for the fans, heating and cooling coils, dampers, blowers, heat wheels, and compressors.
Although the literature for regenerative heat wheels has been developed over 85 years, the literature for regenerative dehumidifier and energy wheels goes back only 35 years.
Most recently, Shang and Besant (2008) presented a theoretical analysis that can be used to correct transient test data for the sensible effectiveness of energy and heat wheels and showed that accurate sensible effectiveness values can be predicted using only the property data of the wheel matrix flow channels, wheel speed, and the inlet airflow properties.
