Advantages
- Good occupant acceptance and satisfaction:
– Individual control
– Opening windows can be used - Good level of energy efficiency:
– System shuts down when not in use or when windows
are opened
– Heat recovery available - Low energy requirement as air is supplied to the room
at low speed and using the shortest possible route - As a result very good fan efficiencies are achieved,
low specific fan powers (SFP) - Very efficient use of space as central air handling plant
and ductwork distribution systems are not required - Often the only practical method to refurbish a building
with a mechanical ventilation/air conditioning system at
an acceptable cost - Simple recording of services costs and simplified billing
for multi rental spaces
