Cool air on hot days – quick guide to air conditioners
25.5.2018
Translation: Eva Francis
Spring is coming to an end, summer is just around the corner and we’re asking ourselves: How hot will this summer be? No matter if you’re a summer or a winter person, air conditioners make sure your home doesn’t turn into a sauna and you can relax and enjoy a cool breeze whenever you want.
As the days are getting warmer and warmer, so are the nights. Many of us have trouble sleeping if the temperatures don’t drop at night and even opening the window doesn’t help. What to do if you’re in need of a cool breeze? Get an air conditioner.
What does BTU mean?
The cooling capacity of an air conditioning application is usually measured in BTU/h. Strictly speaking, this doesn’t refer to the cooling capacity but to how much heat can be removed from the air. Specifically, it is the amount of energy needed to raise 1 pound of water by 1° F. 1000 BTU/h corresponds to about 293 watts. The larger the room to be cooled, the more powerful your air conditioning system should be.
What do you need to look out for when buying an air conditioning system?
Enough theoretical background, let’s get down to the nitty gritty. To find the right system for your needs, use the following rule of thumb: For a room with good insulation and little direct sunlight, multiply the room area in square metres by 60 watts. For a room with poor insulation and a lot of direct sunlight, multiply the area by 100 watts. For a room with an area of 20 square metres, the calculation is 20 m2 × 100 W = 2,000 W. Expressed in kilowatts (kW), this corresponds to 2 kW. As a result, you’ll need a system with a capacity of approx. 7,000 BTU/h for your 20 room.
Mobile air conditioners
Mobile devices can be used wherever you need them – as long as a connection to the outside is given, as the hot air needs to be vented outside. For this purpose, most systems come with a hose about one to two metres long and between 10 and 20 centimetres in diameter, which fits through a half-open window. A more elegant solution, of course, is having a hole in the wall, as this allows you to open and close the windows regardless of the air conditioning system. If you don't have or aren't allowed to drill a hole into the wall, window seals for air conditioners are available under the accessories listed below.
New Electrolux air conditioners
Electrolux now offers mobile air conditioners. This might sound unusual at first, but with their successful range of refrigerators and freezers in mind, it makes sense that Electrolux, famous for kitchen devices, are also specialists for cooling systems.
Split systems
This type of air conditioning system is permanent and requires construction work to connect and allow airflow between the indoor and outdoor component. Therefore, split systems are usually very expensive. An external component is installed on the outside, transporting the warm air outside, while the indoor unit supplies the room with cool air. Split systems are most common in hotels and office buildings. They double as heaters and dehumidifiers.
