What is an Enthalpy Wheel?

An Enthalpy Wheel is a type of Energy Recovery Ventilator (transfers both heat and sensible energy) that uses a rotating air permeable energy exchanger to transfer outgoing temperature and humidity (energy) to the incoming outdoor air. The energy exchangers are generally made of porous materials to increase surface area which aids in energy transfer. [...]

An Enthalpy Wheel is a type of Energy Recovery Ventilator (transfers both heat and sensible energy) that uses a rotating air permeable energy exchanger to transfer outgoing temperature and humidity (energy) to the incoming outdoor air. The energy exchangers are generally made of porous materials to increase surface area which aids in energy transfer. For sensible energy transfer, also called humidity, a desiccant such as Silica Gel or other molecular sieves are added to the device.

Here are some seductive photos of enthalpy wheels… and a nice diagram below to help explain how they work!

  • Henry Gifford Suggests ‘A Better Way to Rate Green Buildings’

  • Henry Gifford, in a recent research paper titled ‘A Better Way to Rate Green Buildings’, offers a well reasoned counter assessment of the USGBC’s interpretation of energy efficiency in LEED buildings, specifically those results announced at the 2007 GreenBuild relating LEED certification to energy performance. In effect, he argues that there is disparity between [...]
