Why does a Truma air conditioning system not have the same cooling output as a car air conditioning system?

In many cases, air conditioning systems are used in cars for just 20 to 30 minutes. A comfortable temperature of about 23 °C should be reached within a very short time. Because cars often have dark colours inside and outside and angled windows, such as the windscreen, they heat up very quickly. This is why car air conditioning systems are equipped with a high cooling output (6 to 8 kW). They are much more powerful, as the compressor of the air conditioning system is driven by the car’s engine. This explains why the engine loses power when the air conditioning system is switched on in the car.

On the other hand, RVs are often used for several hours. The air conditioning system is also used over a long period (while driving or at the camp site). Light external colours and steep windows reduce heating of the vehicle compared to cars. The cooling output of air conditioning systems in RVs is generally much lower, as they are electrically operated and the power supply is limited. This is why a high level of energy efficiency, which ensures optimum cooling output with low power consumption, is essential.

Our air conditioning system can produce a maximum temperature difference of 10°C under optimum conditions, such as when the vehicle is in shadow, is darkened, windows and skylights are closed and humidity is low.
