Energy recovery in mechanical ventilation systems, 43rd Informatory Note on Refrigeration Technologies.

Author(s) : LAZZARIN R.

Type of article: Informatory note

Summary

The thermal loads of buildings, apart from internal gains, can be classified into two main categories: losses or gains through the envelope and ventilation loads.
Ventilation loads are becoming more important as air purity standards and thus fresh air supply rates are increasing. Heat recovery from the exhaust air can strongly reduce these loads by pre-heating or pre-cooling the fresh inlet air.
Heat recovery in a ventilation system allows significant energy savings, particularly when outdoor conditions differ greatly from the indoor ones. Moreover, when a recovery system is provided, the installed capacity for heating and cooling can be strongly reduced.
