Air conditioners - this is the best time

Let's start cosidering a problem arising when it's too late: the purchase of an air conditioner (keep in mind today's date, I warned you!) :D

A client frequently asked question is "Which brand?" Actually it is NOT the first characteristic to consider, but the question is "What to refrigerate?".

First of all, analyse your room (location w.r.t. the sun, walls and windows measures) to evaluate the BTU (British Thermal Unit) needed indicating the cooling power.

It usually varies in a range from about 8000 to 24000 BTU and approssimatively 9000 BTU is suitable for a 25 m^2 enviroment, 11000 BTU for 31 m^2 and 12000 BTU for 34 m^2.

You can use the search engine above and type the keyword "BTU Calculator" to find an euristic BTU calculus needed for your rooms.

Obviously we need to consider if we are also looking for an heating pump function and, in this case, it costs 20-30% more but it is preferable w.r.t. gas stove or fireplace because of harmful fumes.

Another characteristic that let you save money is the choice of a plant with inverter technology: it is possible to trim the power (i.e. the consumption) gradually and with respect to the environment temperature, in opposition to the traditional ON/OFF function (high/null consumption).

Energy classes are related to this function and they varies from A to F, lower to higher consumption.

You can read also about air conditioners mono or dual split: in the first case there are only one external and one internal unit, while in the second case there is always one external unit but two internal units; dual split is probably useful where a pipe plant exists or it can be installed to let pass the refrigerated air from the extern to the intern unit.

Keep in mind that the pipe length must be as short as possible because the longer it is, the higher is the cooling power lost.

Often the unit pair is placed at the same height for the above reason and on the top of the windows for assuring a thermal insulation from the extern, since the cold tends to come out rather than through the walls.

So if you see a special offer from a flying, check the BTU, energetic class, inverter technology, heat pump and mono or dual split.

With reference to this, I advise to check in Italy for the keywords "Expert italia" and "UniEuro". If you are looking for International/Internet offers, need help or want to report comments, feel free to do it. I can help you to find the best buy for E-Commerce sites :)
