What is Roof Mounted Package Air Conditioner? (RTU)
As the name connotes, a Roof Mounted Package Air Conditioner (RTU) is an air conditioner placed on the roof. In an RTU all components like the filter, blower-motor, cooling coil etc. are placed inside one package. Hence the unit is also called Self Contained Package. Cold air is supplied to the room through metal conduits called ducts.
Benefits of a Roof Mounted Package Air Conditioning system for a Villa
1. Health (Improved Indoor Air Quality)
Roof Top Package units can circulate fresh air. Having sufficient fresh air achieves two key objectives:
- a) It pressurises the room and
- b) Increases indoor air quality by diluting polluted or stale indoor air.
Fresh air enters the system through a return air duct vent and then passes over the filter. This air mixes with the return air and is dispersed evenly in the building, through the supply duct system.
