Air-to-air energy recovery equipment, 44th Informatory Note on Refrigeration Technologies.

Author(s) : LAZZARIN R.

Type of article: Informatory note

Summary

Air-to-air energy recovery provides an energy exchange between two air streams at different temperatures and humidities. The energy content of the air can be split into a sensible and a latent fraction. When the energy recovery involves only a temperature difference, the heat exchange is indicated as sensible. If both temperature and humidity differences are involved, the heat exchange is indicated as total, i.e. sensible and latent.
Air-to-air energy recovery is particularly useful in building ventilation, where it can provide fresh air preheating in winter and pre-cooling in summer, with the potential to significantly reduce the energy and financial costs of ventilation.
Many technologies are available for heat recovery ventilation. Heat exchangers can be recuperative (a solid wall separates the two fluids) and regenerative (heat exchange is operated through a solid, permeable material or liquid intermediate system). The heat exchange can be only sensible or total (sensible and latent).
