The various types of air conditioners
Air conditioners are among the various appliances in the home, a "must" that can not be missed especially during the warm seasons and sultry.
In fact, thanks to this appliance, you can lower the temperature of the house to make it bearable and inviting.
Window conditioners
Its function is to cool the air, dehumidify and filtrala. Conditioners on the market are of this type in the range from reduced dimensions with cooling capacity of 5000 BTU / h (sufficient to cool a room of small size), up to conditioners with cooling capacity equal to 12500 BTU / h, suitable to larger environments.
Of course, our advice is to choose before purchasing this appliance, an air conditioner appropriate size. In fact, an air conditioner cools too powerful certainly our house but increases the relative humidity. While a handsome little conditioner, you will not definitely lived up to our every need.
To determine the effectiveness of the cooling enough to have a energy efficiency rating (EER) of at least 9.7 for the models below the 8000 BTU / h and 9.8 for models perform better. Viewed carefully whether the model is the label that clearly indicates.

Portable air conditioners
are suitable for air conditioners cool small spaces. It 'mounted on wheels for easy transport. With the same appliance is possible to obtain both hot and cold air. Of course needs to be placed, at the moment, near a window in such a way that the warm air can be issued outdoors. Some models also contain a tray must be emptied every 24-48 hours.

Oscillating fan
Moves going back and forth in an adjustable manner for the diffusion of air on a wider area. This oscillation can be switched off or gradually increased thanks to a convenient handle. It can be used in virtually any environment and placed on qualsia stable surface.

Installation guide of the air conditioner

Step 1: First you need to calculate the area you want to cool and measure the size of the air conditioner.
Step 2: Once you have decided the arrangement of the air conditioner should proceed to the measurement of the opening of this window in the same room in which we are going to install the unit. We need to insert the air conditioner that we bought into the opening and not all the air conditioners on the market have the same dimensions.
Step 3: Once you have chosen the location to install the air conditioner, install the mounting brackets supplied with the unit, ensuring follow the instructions provided by the manufacturer.
Step 4: Slide the air conditioner into the window and fasten the mounting brackets (again according to the manufacturer's instructions).
Step 5: We lower the window down on top of the unit.
Step 6: We extract the extensions on each side of the air conditioner and agganciamoli to the window frame.
Step 7: We use a piece of foam, sometimes supplied with the air conditioner, by inserting it between the upper part of the air conditioner and the window.
Step 8: Plug in the outer tube to drain the air conditioner.
Step 9:  If necessary, the area around the unit to help keep the hot air out of the room.
Step 10: Plug in the air conditioner to the power and enjoy the long-awaited fresh air.

How to calculate the BTU power required for an air conditioner

Here are some simple steps to follow to calculate the BTU needed to cool our environment. It is highly recommended to perform a step at a time and write down the calculations that at each step will come out!
Step 1: Compute the area of ​​the rooms that we want to cool. To do this we calculate for each room the length and the width (the height of the room in this calculation we do not need). Then multiply the width to the length thus obtaining the square area of ​​this room. Now we add the various areas of the rooms previously taken into account. Since that for every square meter we need around 350 350 BTU multiply the sum previously calculated.
Step 2: We calculate also the sizes of the windows (height by width) present in the rooms that we want to cool. Multiply the square feet to 900 BTU if the window faces south and for 170 if it is exposed to the north. Recall that the south-facing windows are those that let in more light during the day.
Step 3: calculate the number of people who are usually present in the house (in our example) or in our environment that we want to cool. For each person considered 400 BTU.
Step 4: Let's look at our lights. Note the number of watts for each bulb and multiply it by 4.25 BTU. For example, a 100 watt bulb should generate 425 BTU.
Step 5: Check if you have any electrical equipment or machinery that will be running in the rooms to be cooled. Check the maximum power of the moltiplicartela and then to 3.15. Although the maximum power will almost never reached by the appliance is always a good idea to have an air conditioner that also meets these occurrences.
Step 6: We add the BTU calculated at each previous step. We so easily calculated power in BTU needed to cool our room!
