The top-mounted air conditioner takes up little internal space and can be installed in most RVs. Of course, any product has its shortcomings. For example, a camper with a lifting roof cannot be installed with an overhead air conditioner, because it affects the opening of the lifting roof. In addition, some tent vehicles have weak roof support and cannot support the overhead air conditioner, so the bottom air conditioner is the best s Choice. The installation cost of the bottom-mounted air conditioner is relatively higher, because its installation requires the arrangement of air outlet ducts in the motorhome compartment, and the installation is complicated. But the advantages are also obvious. Firstly, the noise is small and will not affect sleep. Secondly, the work efficiency is high. The cold and warm air can be quickly transported to various areas through the pipeline to achieve a rapid heating or cooling effect. Top-mounted air conditioner manufacturers are specific about how to choose which type of air conditioner, and they need to choose the appropriate type of air conditioner according to their own vehicle type.
Some air conditioners use heat exchange to achieve the heating effect, and they often use a simple heating element, similar to the heating element of a heater. For this kind of heating, the heating efficiency is low, but it can work at any external temperature. In the reverse cycle, cooling is to move heat from the inside to the outside, and heating is to move the external heat to the inside. However, this heating method is greatly affected by the external temperature.
This is an important consideration, and salespeople usually ignore it deliberately when describing the benefits of a product. If you plan to use your RV in a very cold climate, you should pay attention to the outside temperature, as this will affect the normal operation of the air conditioner. Or you can directly install an oil/gas heater to solve the problem.
