Heat recovery ventilators (HRV's), as the name implies, bring fresh air into a building while recovering the heat energy in the exhaust air. They are closely related to Energy Recovery Ventilators (ERV), however ERV's differ in that they also "recover" the humidity (or lack of it) in the exhaust air. As residential buildings have become more leak free (aka tighter), the need for HRV's has become obvious. A tight building will require a source of fresh air. It does not make any sense to open the window for ventilation during cold weather, since this destroys the energy efficiency of the building. Hence, the need for an HRV. EXTERNAL LINKS |
