Whoever wants to cool a room should pay attention to the technology, mechanism and energy consumption features. We present a variety of air conditioning systems for different uses, providing you with essential information to make the best purchase.

What aspects to consider before buying your air conditioner

The heat is approaching and the need to cool down to find some relief begins to be a fixed thought. How to find the right air conditioner for your needs? First, rather than a hurried and expensive purchase, consider whether the fan solution is not preferable for the moment, just to get through the most torrid days. Then, early next spring you’ll have enough time to evaluate the purchase of your air conditioner carefully, and will eventually be able to opt for wall mounted air conditioner or a smaller unit.

If, on the other hand, you have decided to buy an air conditioner, after considering some aspects and deciding where to install it, it is important to have an overview of the main solutions available, how much you must be ready to spend and how to use it at best. In case you go for split models, find a serious and qualified installer: a bad installation can compromise the performance and in some cases cause serious damage.

To find the best air conditioner, start choosing the right size

The first thing to evaluate is the size of the space you need to refresh because not all appliances are ideal for all rooms: depending on the square meters of the rooms, in fact, it will be possible to choose a model that can effectively lower the temperatures of the whole environment. This assessment is very important not only for the efficiency of the appliance but also in terms of energy savings.

The parameter to be considered is the so called BTU (British Thermal Unit), used for energy measurement in Anglo-Saxon countries. Depending on the square metres of the room to be air-conditioned, a device with a certain BTU value must be chosen according to the following table:

Room size, in square meters Recommended power, in BTU/h
0 - 10 5000
1 - 15 7000
15 - 25 9000
25 - 40 12000
40 - 50 15000
50 - 60 18000

Different types of air conditioner

There are different types of air conditioners on the market, each one with its pros and cons. Here are the main ones.
  • Portable monoblock air conditioner
    The portable air conditioner is a type of monoblock air conditioner that can be easily moved and is not bound by the outdoor unit as in the case of fixed split air conditioners. Unlike a fixed air conditioner, in a mini air conditioner the drainpipe is not necessarily installed on the wall and can be moved from window to window. Although the performance of the portable air conditioner is lower than that of the fixed split and tends to be noisier, the portable monoblock air conditioner is the ideal solution for home environments and small offices because it is very versatile. Some small air conditioners perform a dual function, cooling and heating.

    The operating principle of a portable air conditioner is very simple: the core of device is the compressor, which cools the refrigerant that is then circulated in a large coil. A fan sucks the hot air from the room and forces it through the cold coil, obtaining a double effect: the air is reintroduced into the cooler room and part of the humidity, which condenses upon contact with the cold metal of the coil, is eliminated. The hot air resulting from compressor operation, together with the humidity accumulated on the coil, is conveyed out of the house through the necessary exhaust pipe.

  • Monoblock air conditioners without external unit
    The air conditioner without external unit is the ideal solution for those who want to air condition their home without affecting the aesthetics of the façade. In particular, it is the priority choice of building technicians to safeguard the aesthetics of historic buildings, but there are few models on the market, costs are not very competitive and performance is lower than models with two units. The engine will be placed in the living room and not outside.

  • Fixed split conditioners
    They consist of an external compressor connected to the internal element fixed to the wall in the room to be cooled. There are models that are only used for cooling and others, equipped with a heat pump, which also allow the air to be heated in winter. In addition to the traditional models, there are air conditioners (now the most common) equipped with an inverter system, which keeps the temperature stable with lower energy consumption.

  • Multi-split
    In this case the external compressor is connected to two or more internal elements. Installation is more complicated than fixed splits, but the advantage is that different temperatures can be set for the various rooms in the house. On the other hand, of course, but consumption is affected.

Where to install the air conditioner and how to use it correctly.

The efficiency of the air conditioners depends not only on the power of the engine, but also on where they are located and on how often they undergo maintenance. To find out where to install the air conditioner optimally and how to keep it efficient, read the details in our dossier.

For a summer use that tends to save money, the ideal temperature to set on air conditioners is 25° C: the valid recommendation is always not to go below 6-7 degrees below the outside temperature, also to avoid health problems. The function that allows costs to be kept down is certainly the dehumidification function which, often, can be enough to obtain a more comfortable climate.

Air conditioner: frequently asked questions

To get the maximum benefit and reduce costs is it better to keep the air conditioner on all the time?

No. Ideally you should turn the air conditioner on only when you are at home and set the desired temperature without exaggerating: a maximum of 6°C less than the outside temperature is enough. Thanks also to the dehumidifying effect, comfort is guaranteed and appreciable in just a few minutes, with a sure saving on your bill.

Portable air conditioning unit or fixed air conditioner: which one to choose?

Portable air conditioners in general are less efficient than wall split air conditioners because they are often a monoblock. In addition to this, it is necessary to leave a gap in the door or window, to place the pipe the heat to escape from the room, and this compromises the air conditioning of the room. Consider that they are often noisier, as the compressor will be in the same room where you are staying.

What is the appropriate temperature?

The best temperature, also in order not to exceed consumption, is around 25°C, but it is always better not to go below 6-7°C compared to outside because an excessive temperature jump can be dangerous for your health. Moreover, electricity consumption is lower if you use air conditioning at a higher temperature.

Is there a difference between the water of the indoor unit and that of the outdoor unit?

There are no differences. You can reuse condensed water for cleaning, for watering - not always because it is demineralised and therefore poor for plants - or for ironing, but in this case follow the manufacturer's instructions.

Do air conditioning filters remove viruses and bacteria? Are they useful for allergy sufferers

The important thing is to avoid water stagnation where bacteria could proliferate, such as Legionella, but the risk in domestic installations is very low.
