In the modern world air conditioner has become not a luxury but a necessity. Hot summer can become a real ordeal if there is no possibility to cool the air indoors. But how to choose the right conditioner, which will work effectively and serve you for many years? The main parameter to consider when choosing an air conditioner is the area of the room. In this article we will consider the basic principles of choosing a conditioner by area, as well as different types of conditioners by functionality and location.
1. Air conditioner capacity and floor area
The basic rule of thumb when selecting an air conditioner by floor area is that for every 10 square metres, approximately 1 kW of air conditioner capacity is required. This is a general rule of thumb and it is important to realise that the final capacity may vary depending on a number of additional factors such as ceiling height, number of windows, isolation of the room, etc.
2. Calculating the capacity of the air conditioner
Let’s make a detailed calculation for a typical flat in Ukraine with an area of 60 square metres. As a general rule, we will need an air conditioner with 6 kW capacity (60 sq.m / 10 sq.m per 1 kW = 6 kW).
But let’s take into account additional factors:
- Ceiling height is usually around 2.7 metres. If the height is higher, increase the power by 20 per cent.
- If the room has many windows, increase the power by 10%.
- If the room is poorly insulated, increase the power by 30%.
In our case, let’s assume that all conditions are standard, so we will leave the power of the air conditioner at 6 kW.
3. Choice of air conditioner by type
After determining the capacity, it is important to choose a suitable type of air conditioner. The main types are:
- Mobile air conditioners. Suitable for small rooms up to 20 square metres.
- Wall-mounted split-systems. Suitable for rooms from 20 to 60 square metres.
- Multi-split-systems. Suitable for large rooms or for cooling several rooms at once.
Let’s make a table that will help you to estimate what capacity of the air conditioner you may need depending on the area of your dwelling.
| Type of dwelling | Area (square metres) | Base capacity (kW) | Additional factors | Total capacity (kW) |
| Flat | 60 | 6 (60/10) | Standard | 6 |
| House | 100 | 10 (100/10) | High ceilings (+20%), manywindows (+10%) | 13 (10*1.3) |
| Large house | 200 | 20 (200/10) | High ceilings (+20%), lots of windows (+10%), poor insulation (+30%) | 32 (20*1) |
This table is only a general guide. An individualised approach is required on a case-by-case basis and additional factors may need to be examined in detail.
4. Types of air conditioners by location type
In addition to choosing the capacity of the air conditioner, it is important to consider its type of location. There are the following main types of air conditioners:
- Wall-mounted air conditioners
These are the most common type of air conditioners that are mounted on the wall. They are ideal for most homes and offices. The advantages of these air conditioners include ease of installation and cooling efficiency.
- Window-mounted air conditioners
Window air conditioners are installed directly into a window opening or into a specially made niche in the wall. They are an economical option and are suitable for cooling small spaces.
- Cassette air conditioners
This type of air conditioner is installed in a suspended ceiling and provides even distribution of cooled air throughout the room. Cassette air conditioners are ideal for large rooms such as offices or retail halls.
5. Types of air conditioners by functionality
An important criterion in choosing an air conditioner, apart from its capacity and type of location, is its functionality. Let’s consider the main types of air conditioners according to this parameter.
- Cooling air conditioners
This is the most basic type of air conditioners. Their main function is to cool the air in the room. They usually have a lower cost and are easy to use.
- Air conditioners with heating function
These air conditioners can not only cool but also heat the air, making them a convenient option to use all year round. They work on the principle of a heat pump, switching between cooling and heating modes.
- Air conditioners with air purification function
Some models of air conditioners have inbuilt filters to clean the air. They can remove dust, allergens and other harmful particles, improving indoor air quality.
- Air conditioners with humidifying function
These air conditioners, in addition to cooling the air, also humidify the air, which is especially useful in dry and hot climates.
- Air conditioners with inverter
Inverter air conditioners use special technology that allows them to operate more efficiently and quietly. They automatically adjust the speed of the compressor depending on the temperature in the room, which saves energy.
Choosing an air conditioner based on the area of the room is an important step towards a comfortable and cool summer. It is important to remember that a properly selected air conditioner will not only make your life more comfortable, but will also save energy. The type of conditioner, its power and functionality should be selected taking into account the area of the room, its layout, and, of course, your personal preferences. Do not forget to take into account all factors: ceiling height, number and area of windows, the degree of thermal insulation of the room, as well as your individual preferences. As a result, by choosing the right model, you will get the perfect solution for your home or flat. And remember, professional advice will always help you!
