Air-to-Air Heat/Enthalpy Exchanger Heat Recovery Devices. In order to enable a range of different device types to be modeled, a fairly simple representation of the heat recovery process has been used. This describes the sensible and latent heat recovery potential in terms of device effectiveness (see ASHRAE handbook for definition and
The ERB is Counter flow and sensible heat exchanger. Two air streams arepassed though the separate air channel and exchanged the energy. This design not only improvesthe heat transfer area, but also recovery the energy efficient. Material type of Counterflow Air to air plate heat exchanger Heat Exchangers:Engineering Reference EnergyPlus 8.2The sensible and latent air-to-air heat exchanger is typically used for exhaust or relief air heat recovery. Heat exchanger performance can be specified to transfer sensible energy, latent energy or both between the supply and exhaust air streams. The input requires no geometric data.
The effectiveness of an air-to-air heat pipe heat exchanger is the ratio of the energy transferred versus the maximum possible amount of energy that could be transferred for the conditions that it is exposed. For sensible only devices like heat pipe heat exchangers, the effectiveness is typically reported as temperature effectiveness. Heat and Mass Transfer in Air to Air Enthalpy Heat ExchangersA computational fluid dynamics code is used to study the heat and moisture transfer distribution in the heat exchanger using sensible- latent effectiveness ratio Due to concerns over indoor air
·Material of sensible heat exchanger The sensible heat exchanger core is made of high quality hydrophilic coating aluminium foil, with fast thermal conductivity, no secondary pollution and high heat transfer rate. According to different occasion, the epoxy coating aluminium foil is able to choose from, which with higher corrosion resistance. Air-to-Air Heat Exchangers For Healthier Energy-efficient
