The cooling power from a motorhome air conditioning system differs from that of a classic vehicle air conditioning system, which operates using the vehicle’s engine.
The air conditioning system for a motorhome ensures a much more comfortable climate by minimising heating indoors, improving the complete room climate through dehumidification and enabling undisturbed sleep with pleasant temperatures and quiet operation.
What effect do temperature and humidity have on my well-being?
A pleasant indoor climate is achieved by a combination of temperature and humidity: as the room air temperature increases, humidity should decrease. In other words, an air conditioning system should also lower humidity. The recommended conditions for a comfortable vehicle are temperatures from 18 – 24°C and 40 – 70% humidity.
The chart below, courtesy of Truma, shows the range in which the indoor climate is perceived as pleasant, with a temperature of 27°C and 65% relative humidity as an example. The comfort zone can be achieved with a compressor air conditioning system (dark blue arrow), but not with an evaporative system (light blue arrow).
How do I choose between a roof mounted air conditioner or a storage box air conditioner?
Roof-mounted air conditioning systems are especially quiet, light and powerful. They can be used in many different types of vehicle and can be installed quickly on the roof of your caravan or motor home and are very easy to retrofit. They don’t take up storage space. They also cool directly via the inside air distributor and the air outlets can be adjusted individually.
The storage box air conditioning systems are installed in the vehicle’s storage compartment, which means they are hidden from view and not blocking a vent or roof space. They have many options for distributing cool air through ducts to specific areas of the vehicle, such as to a room behind a closed door. They are lightweight and, because of the low centre of gravity, have a positive effect on the vehicle’s roadability. But the installation may be more time consuming.
