Mobile Air Conditioners Test & Guide

Mobile air conditioners are a practical way to cool down comfortably in hot temperatures. Unlike permanently installed air conditioners, which can usually only be installed in residential and commercial premises with appropriate preparation, mobile air conditioners are easy to transport and can be used in different rooms and even outdoors or in caravans and while camping. In our guide, we'll show you different models of mobile air conditioners, their functions as well as advantages and disadvantages.

Mobile air conditioners: Comparison of features and performance

In principle, mobile air conditioning systems work like conventional air conditioning systems by sucking in warm air, cleaning it through a filter and then cooling it down again with the help of refrigerants. However, there are some differences that should be considered when choosing a portable air conditioner. For example, the performance of the devices depends on the size of the room and the outside temperature. There are also different models with different features, such as timer functions, ventilation levels or air purification systems. There are also differences between the devices in terms of energy efficiency and volume, which should be taken into account when making your selection. So that you can choose the perfect mobile air conditioner, we will now show you the different types. Whether with or without an exhaust hose, as a smart device or another air conditioner: You will definitely find what you are looking for in our range!

Frequently Asked Questions

How does a mobile air conditioner work?

A mobile air conditioner draws in the warm room air, cools it through evaporation and releases it again as cool air. The moisture is extracted from the air and routed outside through an exhaust air hose. You can adjust the temperature and fan speed to create a comfortable indoor climate.

How much electricity does a mobile air conditioner use?

The power consumption of a mobile air conditioner depends on its performance and energy efficiency class. When buying, pay attention to the energy label and the information on power consumption in order to be able to estimate the costs of operation. The power consumption for a mobile air conditioner with energy efficiency class A can be between 900 and 1200 watts, depending on the model and output.

Can you heat with a mobile air conditioner?

No, a mobile air conditioner cannot be used for heating as it only has a cooling and ventilation function.

Which mobile air conditioner is right for caravans?

There are special mobile air conditioning systems for caravans that are tailored to the conditions and needs in the camping area. An example is our Klimamobil caravan air conditioning system. If you would like to use a standing device, we recommend a small and particularly quiet device. Here, you can choose an economical and not so powerful device to save on electricity costs.

How does a mobile air conditioner with an exhaust hose work?

A mobile air conditioner with an exhaust air hose works by sucking in warm room air and passing it through a cooler, which cools the air. The heat is directed outside while the cool air is fed back into the room. Operation typically requires an outlet to power the air conditioner.

How does mobile air conditioning work without an exhaust hose?

From a technical point of view, a mobile air conditioning system without an exhaust air hose is not possible, since warm air always has to be removed when the air is cooled. However, there are air coolers. These come without an exhaust hose. An air cooler is a device that reduces the room temperature by evaporating water and circulating air.

Can you dehumidify with a mobile air conditioner?

Yes, a mobile air conditioner can also act as a dehumidifier, pulling moisture out of the air and draining the condensation through the exhaust hose or a separate container.
