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.

Awada says: "Fresh air is introduced to the building via three fresh air handling units to improve the indoor air quality, which comprises of a heat wheel recovery wheel and run around heat pipe air handling units located on the roof and provided by chilled water via two small dedicated water cooled chillers of 70 tons each."
Having achieved LEED Gold certification, this is one of the first approved clinical facilities in the state of Pennsylvania to utilize active chilled beam technology with enthalpy heat wheel recovery.
This heat wheel cleans itself fully automatically during the ongoing finishing process.
Fortunately this can generally be supplied in cold weather with heat wheel operation alone.
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.
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.
This term is defined as a recuperator, heat wheel, regenerator, heat exchanger, waste heat boiler, heat pipe, automatic energy control system, turbulator, preheater, combustible gas recovery system, economizer, alumina electrolytic cell modification, chlor-alkali electrolytic cell modification, or any other property of a kind specified by regulation by the Secretary of the Treasury.
Depending on your climate, your facility may be better served by a heat wheel, which cools outside air in the summer and heats it in the winter, or a total energy recovery unit, which transfers both heat and humidity using a desiccant media that can adsorb and release molecules.
The minimum outside air system for the dual duct system has a total energy heat wheel and a chilled water cooling coil to precondition the ventilation air delivered to the unit decks.
A heat wheel, also called an enthalpy wheel, is an energy recovery device used in building ventilation systems to transport both dry and humidity heat.
