Summary Cost Overview

Conclusion
The choice of a mobile air conditioner type depends heavily on the intended use, noise level, desired comfort, and available budget. For intensive use or bedroom cooling, a mobile split air conditioner is the best choice. For occasional or budget-oriented use, a single-unit or air cooler will suffice.

A mobile air conditioner with exhaust hose is the most common portable cooling solution for private users. This type of device draws warm air from the room, actively cools it, and discharges the excess warm air through a flexible hose that leads outside. This system is suitable for occasional or temporary cooling in, among other things, bedrooms, offices, and rental homes.

Operation

A mobile air conditioner works on the basis of a closed cooling circuit, similar to a refrigerator. Warm indoor air is drawn in, cooled and blown back into the room. The dissipated heat is conducted outside via an exhaust hose, usually via an open window or door.

• Exhaust hose: Diameter ± 125–150 mm, length usually 1.5 to 2 meters
• Exhaust through window or door: Requires window sealing kit for better efficiency
• Power supply: Works on standard 230V socket
• No installation required

Advantages

• Immediately usable without installation or technical knowledge
• Movable to different rooms thanks to wheels
• Low purchase costs (from €250) compared to fixed systems
• Ideal for temporary cooling or use in rental properties

Limitations

• High noise production: Average 55 – 65 dB, audible during use
• Energy consumption: Less efficient than split units, especially with poorly sealed windows
• Heat leakage at window: If there is no good window seal, warm outside air flows back in
• Limited cooling capacity: Effective for smaller spaces (up to ± 30 m²)

Practical considerations

• Choose cooling capacity: A minimum of 2.5 kW is recommended for bedrooms
• Keep the exhaust hose as short as possible and without bends for optimal operation
• Window sealing kit strongly recommended to improve efficiency
• Clean the filter regularly (once every 2 weeks with intensive use)

Conclusion
A mobile air conditioner with an exhaust hose is an accessible solution for temporary cooling, with direct deployment and low investment costs. For structural use or noise-sensitive applications (such as bedrooms), a split air conditioner is often a better choice in terms of comfort, efficiency and noise level.

A mobile split air conditioner is a movable cooling solution consisting of two separate parts: an indoor unit and an outdoor unit, connected by a flexible hose. Unlike traditional mobile air conditioners with an exhaust hose, this version dissipates heat outside via the external unit. This system combines some of the efficiency and quietness of fixed split units with the flexibility of mobile devices.

Structure and Operation

• Indoor unit: Movable unit with fan and controls
• Outdoor unit: Small and light unit placed outdoors (balcony, windowsill, terrace)
• Connection: Flexible refrigerant pipe (usually 2 – 4 meters long, quick coupling)
• No permanent installation required: Suitable for temporary or seasonal use

Advantages over standard mobile air conditioners

• Quieter: Indoor noise level often only 35 – 45 dB
• Higher efficiency: No heat loss through the window, more efficient heat dissipation
• Better cooling comfort: More constant temperature, no annoying drafts
• No window seal required

Limitations and points to consider

• Higher purchase price than standard mobile units
• Temporary outdoor unit setup required
• Flexible refrigerant line requires careful handling
• Not intended for permanent installation (fixed systems are subject to F-gas regulations)

An aircooler, also called an air cooler, is a device that cools air through the evaporation of cold water or ice. Unlike an air conditioner, an aircooler does not use refrigerant or a compressor and does not require a drain hose or an outdoor unit. It is a simple and energy-efficient solution for light cooling, especially in smaller or well-ventilated spaces.

How it works

An air cooler draws in warm air through a wet filter. As air flows through this filter, some of the water evaporates, slightly cooling the air and blowing it into the room with added moisture. This process is called adiabatic cooling.

• No coolant or mechanical cooling system
• Works with cold water or ice cubes in a built-in reservoir
• No drain hose or outdoor unit required
• Mobile and immediately deployable

Advantages

• Low purchase costs (from €75)
• Low energy consumption (usually < 100 watts)
• No installation required
• Compact and portable
• Also functions as a fan and humidifier
• Environmentally friendly: No coolant or high CO₂ emissions

Limitations

• Limited cooling capacity: Cools only a few degrees, depending on humidity
• Effectiveness decreases in high humidity (as in warm, stuffy weather)
• Not suitable for long-term or structural cooling
• Increases humidity, which can be uncomfortable in poorly ventilated spaces

Estimated Prices (2025)

Popular brands: Honeywell, Clean Air Optima, AEG, Klarstein, Trotec

Application

• Suitable for: Small bedrooms, home office, temporary cooling in dry air
• Not suitable for: Large spaces, hot humid summer days, long-term cooling
• Ideal for: Limited budget or where a fixed or mobile air conditioner is not desired

Conclusion
An air cooler is an affordable and user-friendly solution for light cooling on warm days, especially in dry environments. It is not a replacement for air conditioning, but can offer temporary comfort with limited use and good ventilation.
