Difference between RV Rooftop Air Conditioners and Bottom-mounted Air Conditioners

In recent years, more and more people own RVs and understand that there are several forms of RV air conditioners. According to the scenario of use, RV air conditioners can be divided into traveling air conditioners and parking air conditioners. Traveling air conditioners are used while the RV is in motion, and parking air conditioners are used after arriving at the campground. There are two types of parking air conditioners: bottom-mounted air conditioners and top-mounted air conditioners.

Rooftop air conditioners are more common in RVs, and we can often see the part of the RV that protrudes from the top, which is the overhead air conditioner. The working principle of overhead air conditioner is relatively simple, the refrigerant is circulated through the compressor on top of the RV, and the cold air is delivered to the indoor unit through the fan. The advantages of roof-mounted air conditioner: it saves interior space and the overall interior is very good-looking. Because the overhead air conditioner is installed in the center of the body, the air will come out faster and more evenly, and the cooling speed is fast. Disadvantages: The air conditioner unit is on the roof of the car, which increases the height of the whole car. And because the air conditioner is on the roof, it will make the whole car vibrate and resonate, and the noise will be relatively large. Compared to bottom-mounted air conditioners, top-mounted air conditioners are more expensive. In addition, in terms of appearance and construction, rooftop air conditioners are easier to replace and maintain than bottom-mounted air conditioners, but the indoor unit is on top of the caravan, which will bring corresponding noise.

Bottom-mounted air conditioners are usually installed under the bed or at the bottom of a car seat sofa in an RV, where the bed and sofa can be opened for later maintenance. One of the advantages of under-bunk air conditioners is that they reduce the noise they make when they are in operation. The under bench air conditioner is installed under the seat or sofa, occupying a small area, and can be installed anywhere according to your needs. However, the installation is difficult and expensive.
