downstream energy wheel during extreme winter conditions. Required fields are marked *. Heat and moisture are given up to the wheel. Energy Wheel Technology The total energy wheel is constructed of a polymer heat transfer media for sensible energy transfer and a silica gel desiccant that is permanently bonded to the polymer media for latent energy transfer. Energy recovery wheels are self-cleaning in nature with respect to dry material. Outside air then enters the energy wheel module, which is the unique feature of this air handling unit. Airxchange energy recovery wheels are available through most major HVAC OEMs in a wide variety of configurations. Introduction The air-to-air rotary energy wheel, as a widely-used energy recovery unit, is used in building HVAC system to recover/reject both sensible and latent heat energy from/to the exhaust airflow of air handling units. Air Handling Unit (AHU), as a system for space heating and cooling is one of the most relevant causes of energy consumption in both residential and tertiary sector buildings. An energy recovery wheel at a casino in Toledo, OH, generated 13.02% energy savings above the ASHRAE 90.1-2007 baseline. Total energy wheels are the most efficient energy recovery devices currently available in the market. ERVs use an optional ECM-driven energy wheel designed to recover energy from the exhaust air stream and transfer it to the fresh air stream brought into the building. Enthalpywheel is not the term.

A spinning wheel, or stationary core device utilizes the counter-flow of air to remove the stale air from inside a building, while retaining air temperature. ENERGY RECOVERY WHEEL ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality, defines the minimum outdoor air ventilation rates required to achieve acceptable indoor air quality. Recycles energy to eliminate fresh air energy cost concerns leading to a healthier building environment Per ASHRAE guideline V, a typical Airxchange wheel can improve HVAC system efficiency up to 40%, preconditioning outdoor air at efficiencies equivalent to 60 EER Provides up to 4 tons of cooling per 1000 CFM of outdoor air Because the cost to remove moisture can represent 30 to 50% of the cost to condition air, substantial additional savings are available with enthalpy wheels over conventional air-to-air exchangers. In most cases a matrix core material is coated with a desiccant such as Silica Gel or other molecular sieves to increase latent transfer. Figure 1 illustrates the heat transfer process of an energy recov- They reduce energy bills by using the expelled air to heat (or cool) the incoming air, depending on the season. Sign Up Today. In the cooling mode, the incoming air is pre-cooled and dehumidified. The main function of regenerative air-to-air rotors is the transfer of sensible (temperature) and latent (humidity) energy between exhaust and supply airflows. Energy savings of 1% AHU leakage compared to 5% = $5,271 per year. EUROVENT MS 200 (AHRI) MS 270A (AHRI) The EcoFresh Energy Recovery Wheel, which recovers total energy (sensible as well as latent), assists in meeting all the requirements of Indoor Air Quality (IAQ), humidity control and energy saving.
