a) Central Mechanical Ventilation Including Heating, Cooling and Heat Recovery:
By recovering the residual heat in the exhaust gas, the fresh air introduced into the air conditioning is pre-heated which ultimately improves the energy efficiency.
b) Central Mechanical Ventilation with Heating and Cooling:
Intentional exchange of indoor air and fresh outdoor air at a controlled rate using fans.
c) Local Ventilation (e.g. Window/Wall/Roof Units):
Packaged unit components are housed in one cabinet which is directly connected to the ventilation system to circulate the air.
d) Other Local Units (Fan Coil Units):
Fan Coil Unit is a simple device with heating and cooling coil to circulate the air.
Following are the factors from the 'Standard EuP Lot 11: Fans for Ventilation' that are used for the calculations regarding 'Specific Fan Power' of cove.tool:
