| Fan | Air Cooler | Portable Air Conditioning | |
|---|---|---|---|
| Cooling Type | Thanks to its airflow, a fan offers a pleasant refreshment on hot summer days. It helps regulate the body temperature and gives us a cooling sensation, even if the room temperature itself is not reduced. | The air cooler draws warm air in, evaporates water and cools the air flowing through it. This ensures that our body is pleasantly cooled, even if the room temperature itself is not significantly reduced. | The mobile air conditioning system ensures a pleasant cooling of the room. The warm summer air is drawn in and cooled down by a compressor, like in a refrigerator. The resulting warm air is led outside through an exhaust hose. |
| Weight | The weight of fans (depending on the model) is usually between 1-8kg. | The weight of air coolers is between 6-10kg. | The weight of monoblock systems is between 10-30kg. |
| Cooling Capacity | No direct reduction in room temperature | No direct reduction in room temperature | The cooling capacity of mobile air conditioning systems is usually between 2-3kW. This allows the cooling of a room with a volume of 80-120m³. The mobile air conditioning system is therefore more suitable for small rooms and rather for sporadic use. |
| Power Consumption and energy efficiency | Of all the devices listed here, fans usually have the lowest power consumption. | Compared to monoblock and split air conditioning systems, an air cooler performs better in terms of electricity costs. | The power consumption of these devices can even be higher than with a modern split air conditioning system. Therefore, monoblock devices are particularly well suited for sporadic use. |
| Sound Volume Level | On average, fans are quieter than other air con units. | Air coolers work without a compressor and therefore cool the room air much more quietly than the other air conditioning systems. | The mobile devices reach a volume between 60-65dB and are therefore the loudest in comparison to other cooling devices. |
When purchasing a new air conditioning system, cooling performance is an important factor. A comparison of different models shows that performance can vary greatly. The amount of thermal energy that the device dissipates per unit of time has an impact on the operating costs. In addition, it is important whether the selected device is optimal for the respective room size. If the unit is too small, the room will not be cooled adequately. An oversized choice, on the other hand, is also not recommended. Two units of measurement are important to determine the cooling performance: BTU and (kilo) watts. BTU stands for British Thermal Unit and denotes the cooling capacity (per hour) for air conditioning systems.
With this rule of thumb, you can determine the appropriate cooling capacity for your room size: calculate your room area in square meters times 60 watts (with good insulation and little sun exposure) to 100 watts (with little insulation and high sun exposure). Example:
20 m² x 100 W = 2000 W
(1000 W = 1 kW = 3412,14 BTU)
In a 20 square meter room with little insulation and high solar radiation, you will need a device with a cooling capacity of 2kW and around 6800BTU/h.
In addition to insulation and solar radiation, the number of people and technical devices in the room also influence the selection of the appropriate cooling capacity. Add about 250 watts for each additional person and the wattage for each electronic device in the room. You can find out the consumption of a device in the operating instructions or on the type label of the device.
Consequently, you will need more powerful devices to get efficient cooling for larger rooms. In smaller, sporadically used, rooms, you can use a mobile air conditioning system with an exhaust hose (there are no versions without a hose) . A permanently installed device is an ideal air conditioning option for the bedroom, but the costs are usually somewhat higher.
Frequently Asked Questions
What is the ideal positioning for my air condioning devices?
What is a multi-split system?
This variant allows the connection of several indoor units to the outdoor unit. Depending on the version, up to 5 indoor units can be connected. Therefore, you can cool several rooms or entire floors with this variant.
Can I install an air condionter split system myself?
We can absolutely advise against this. You should definitely leave this task to an experienced specialist company. Specialist know-how is indispensable for the planning and assembly of these complex systems. Furthermore, no specialist company is liable for possible errors and damage that may occur during self-installation. A leaking coolant from an improper installation, can have serious consequences for health and the environment.
How often should air conditioning units be serviced?
For larger systems with a fill volume of around 2.5 to 3kg, maintenance is recommended once a year; for smaller units, a maintenance interval of 2 to 3 years is usually sufficient. Thereby, the filter can be checked and replaced, if necessary. The maintenance is usually carried out by air conditioning, heating and sanitary specialists. The refrigeration technology of complex systems can also be checked regularly by an electrician.
Why my cooling devices is no longer work like it used to be?
There can be various reasons for an insufficient cooling capacity. For example, an insufficient amount of coolant or a defective or dirty filter might be the reason. If in doubt, you should contact a specialist company.
What needs to be considered when I try to air conditioning the room?
Basically, you should pay attention on the relationship to the environment in relation to relative humidity and temperature. It is advisable not to cool the respective room by more than 6 degrees compared to the outside temperature. This is advisable in order to avoid colds and circulatory problems due to an excessive temperature difference. If the humidity is too low, it can dry out the mucous membranes and thus irritate the respiratory tract. If it is too high, however, it can have a negative effect on the thermoregulation of the people in the room. A humidity of around 50 to 60 percent is ideal.
How environmentally friendly are the air conditioning systems?
In the air conditioning test of the Stiftung Warentest, it was pointed out that the effects on climate depend on the choice of the cooling agent. Nowadays, legislators are ensuring that modern systems have to meet high requirements for approval.
How do you disinfect an air conditioner?
Yes. Many companies offer special disinfection sprays with which you can disinfect your systems and thus prevent the formation of germs and fungi.
