- 1- Air-to-Air Energy Recovery is the process of recovering energy or/and moisture from an air stream at a high temperature or humidity to an air stream at a low temperature or humidity
- 2- This process is important in maintaining acceptable indoor air quality (IAQ) while maintaining low energy costs and reducing overall energy consumption.
- 3- Energy can be recovered either in its sensible (temperature only) or latent (moisture) form, or combination of both from multiple sources.
- 4- Units used for sensible energy recovery are called sensible heat exchange devices or heat recovery ventilators (HRVs).
- 5- Devices that transfer both heat and moisture are known as energy or enthalpy devices or energy recovery ventilators (ERVs).
- 6- HRVs and ERVs are available for commercial and industrial applications as well as for residential and small-scale commercial uses.
