Air Conditioner DesignAir conditioning designs vary according to make and installation location. We basically have two kinds of air conditioners: The ducted and non-ducted models.The ducted models are less bulky due to the fact that they lack a control unit. The air conditioner can be fitted on the rooftop and still work effectively.The cooled air is then transported using ducts to supply the whole space with conditioned air. It is convenient for those hot summer days where you need every location in the RV cool. This is more suited to RVs that already have ducts.Airxcel 48204C866 08-0080 Mach 15 15.0 Arctic Wht UpperNon-ducted models work a tad bit different from the ducted. They are commonly placed on top of the RV and include a compressor, blower, and a condenser.They work by sending individual refrigerant to the blowers that may be located elsewhere in the RV. It is less dusty and covers different locations in the RV. If you do not have ducts in your RV this might be a better option.All about the BTUsWhen it comes to air conditioners powers we measure power using BTUs. The BTUs stands for British Thermal unit.
