In today's market, there are a vast number of equipment models. There are budget, middle class, and premium segments. The cost depends not only on functions and stylish design.
Energy-saving technologies are expensive for manufacturers, so they are laid at the original price. But after a few months, such a product pays off the investment, as electricity bills are sharply reduced. On the contrary, budget models are hardly economical.
It is crucial to evaluate the noise, the refreshing, and antibacterial filters. Advanced users create ratings so that beginners can choose the best option. We will talk about ideal window air conditioners for rooms ranging in size from 14 to 42 m2 in this article.
Which window air conditioner to choose from?
Window air conditioning and portable models are the smallest in size range. Window air conditioners are suitable for small rooms. They are useful if the parameters of the windows allow you to install air conditioning. This option is the most compact.
If this is not possible, classic split systems come to the rescue. But the owner of the apartment or house will have to allocate space on the floor for the indoor unit. You will also need to stretch a special hose from the indoor unit to the outdoor on the street. Both options work very quietly and provide comparable performance.
How to choose the right size window air conditioner?
The size of the housing must be selected depending on the area of the room. It is not only about the fact that the small device fits better into the design and does not clutter up space on the wall, floor, or ceiling. The larger the air conditioning, the more powerful it is. Excessive power will cost the client more. Too small models can adjust the climate not fast enough and not good enough.
A common mistake is an opinion that it is better to buy a more powerful device. Of course, it can be set to a minimum limit. But such equipment consumes more electricity and wears out more. As mentioned earlier, a powerful air conditioner still takes up more space. Therefore, to choose the optimal model, it is necessary to make professional calculations.
The ability of equipment to cool the air manufacturers indicates in BTU the number of square meters. It is a British measurement system; the BTU value for each model is printed on a box or case and duplicated in catalogs and on the company's website. There is a direct relationship. The larger the room, the higher the BTU value.
When calculating, it is desirable to take into account the following details:
- The height of the ceilings, windows, and doorways.
- A number of windows and doors.
- The area of individual rooms and the whole house.
- Layout and number of floors.
- The material of the roof and walls, the presence of insulation.
- The desired temperature in the rooms
- Location of rooms (sunny or north side).
For proper installation of a window or wall air conditioner, it is necessary to make the correct geometric measurements. There should also be free space around. This facilitates future access to the system for preventative maintenance. Also, the open space around the air conditioner improves air circulation.
How to determine the energy efficiency of equipment?
Manufacturers designate energy efficiency ratings as EER. It is enough to divide the BTU of the device by the power consumption in watt-hours to measure it. High levels of EER mean significant savings in electricity bills. Energy-efficient models of air conditioners are more expensive due to the introduction of new technologies. But this technique pays off within a few months.
Owners of old air conditioners (older than 5 years or more) are beneficial to replace them with new ones. Such investment returns very quickly. At the same time, the buyer receives additional functionality, comfort, and modern design.
Many brands equip window air conditioning with energy-saving modes. It means that when the equipment is not used, it automatically turns off. For this, manufacturers integrate sensors in the case that respond to movement in the room. Another opportunity to increase energy efficiency is the presence of automatic modes.
When the set temperature is reached, the air conditioner sets the optimum engine speed to maintain the result. Since the system does not turn off, this eliminates temperature fluctuations and reduces electricity consumption.
Power-saving night mode means minimal cooling. It reduces the noise level so as not to interfere with restful sleep. Also, the temperature in the room rises slightly, which does not allow to freeze, being without movement.
Features of a window air conditioner
- Most models have fine-tuned temperature and humidity settings. The user can add or decrease the value by 0.5 ° C and 1% humidity. Some models may work in fan or room heating mode.
- The filter indicator lights up when it needs to be replaced or cleaned. Filters trap large particles of dust, viruses, and bacteria. Deodorizing cartridges can decompose odors and work on the principle of drawing.
- Oscillations of the curtains near the openings of the body better distribute the airflow. Their orientation can also be adjusted in the settings. It allows you to disperse fresh air as efficiently as possible.
- The remote control works from a distance of several meters and sets the modern standard for the use of electronics.
- Smart air conditioners are equipped with Wi-Fi. With it, users control the system while away from home via smartphones.
