For caravans, there are several types of air conditioner: roof-mounted air conditioner and bottom-mounted air conditioner.
Top-mounted air conditioner is the most common type of air conditioner for caravans. It is usually embedded in the centre of the roof of the vehicle, and because the cold air goes downwards, it makes it easier for the cold air to reach all areas of the vehicle. Roof-mounted air conditioners are more like window air conditioners in that they are integrated inside and outside, with the inside unit inside and the outside unit outside. However, generally speaking, because it is designed specifically for caravans, the noise and vibration from the compressor of the outside unit is less transmitted than in a window air conditioner. But for lighter sleepers it may still be a noticeable nuisance. Overhead air conditioners take up little space in the vehicle, but can increase the height by 20-30cm, although in the case of large frontal caravans, where the frontal area is already high in order to increase bed space, adding another overhead air conditioner in the middle of the roof may have no effect.
A more upmarket caravan-specific air conditioner is the bottom-mounted air conditioner. This is the equivalent of a small central air conditioner, with the outside unit in the chassis or under the bed connected to the outside of the car, and then the cold air is ducted to a number of places in the car, and because the cold air goes downwards, the air outlet is usually also located high up to improve the cooling effect. Because the outside unit is completely outside the car and is underneath the car which has the relatively best sound and vibration insulation, the under-bed air conditioner has minimal noise and vibration and, together with the central air conditioner design, the best cooling effect. It also doesn't take up much volume.
