01
INTRODUCTION
Whether it's a new home or office, or the desire to prepare the rooms by anticipating the classic summer heat wave that usually corresponds to a widespread increase in the prices of air conditioning systems, the choice of air conditioning and the most suitable air conditioning system it is a rather important moment and that necessarily requires precise evaluations and great attention.
In addition to economic reasons, in order to understand which air conditioner is best suited to our specific air conditioning needs, it is first necessary to clarify some fundamental points for an optimal choice: currently, in fact, various types of air conditioner, each with its own characteristics and its qualities. First of all it is important to keep in mind that air conditioners are on sale today, which perform a dual function depending on the time of year: air conditioning in summer and heater in winter (the so-called heat pump).
The main benefits that a 360 ° climate system is able to offer, are based on maximum comfort and in very low running costs, for a perfect climate all year round. So, before choosing the type and model best suited to our environments, it is good to understand if the appliance can also be used for heating for the winter and if this function can actually be useful.
Heat pump air conditioners generally cost 30-40% more than others, but have a climate control function with integrated control of the air humidity and automatic temperature regulation.
Another important distinction is that between residential air conditioners (specially designed, also from the point of view of materials, for a purely domestic use) and commercial air conditioners (designed to best fit the particular needs of offices, shops or other work environments. ). Naturally, in this case the most evident difference is that linked to the powers of the single external units and to the maximum number of internal units that can be associated with them, as well as their type.
Other aspects to consider in order to make the right choice:
  • Current technologies do not limit their intervention to the cooling or heating of the air present in the surrounding environment, but they even purify it by means of special multi-layer anti-allergic and anti-pollution filters, and / or through sophisticated additional functionalities.
  • As far as filtration levels (or layers) are concerned, there are several which can completely eliminate dust, bacteria and viruses, neutralizing bad odors and arriving to sterilize the air in transit for an even healthier and allergen-free environment.
  • Among the most advanced technologies in this sector, we find the Silver Ion: a filter made with silver particles capable of eliminating the bacteria present in the air and controlling the proliferation of polluting organic agents such as viruses, spores and fungi, destroying their configuration internal and literally absorbing the cellular elements. The Silver Ion is a widely tested filter that guarantees the elimination of more than 99% of bacteria in the air-conditioned environment.
  • The set of characteristics of purity, healthiness, hygiene, humidity and comfort of the air inside the environments in which we live is also known as IAQ (Inlet Air Quality).
  • Many state-of-the-art air conditioners are able to satisfy any type of requirement and temperature, thanks also to the presence of advanced functions such as independent dehumidification and silent ventilation, guaranteeing reduced energy consumption with minimal environmental impact.

HOW TO CHOOSE THE RIGHT AIR CONDITIONER?
On what criteria do you opt for one model, rather than another? To be able to make a prudent and conscious choice, it is first of all necessary to do some clarity. The most important thing, if you are undecided about what is best to buy, is to turn to air conditioning specialists to get advice in a precise and professional way. In this guide you can find some indications and basic elements, useful to guide you in your evaluations.
 
03
AIR CONDITIONERS CLASSIFICATION
The inverter air conditioners guarantee a good yield in continuous use. The Inverter technology, in fact, involves the use of a thermostat able to regulate the temperature setting it to the desired levels according to your needs, and to keep it stable by adjusting to the minimum.
In this way, and thanks also to systems of automatic dispensing variation based on the actual cold demand, an inverter system is the ideal solution for those who need constant, silent and energy-saving operation over time.
The on-off air conditioners, no longer on the market, were characterized by greater consumption as they were able to deliver greater volumes of air with continuity in the thrust.

TYPES OF AIR-CONDITIONER INSTALLATION
The types of installation of air conditioners are essentially two: fixed air conditioning and portable air conditioning.
The fixed systems can be divided, in turn, into air conditioners with external units, condensed to water and monoblock. In the first case it is necessary to install an external motor and some internal units, while in the second case the motor (water condensed) can be installed inside the house. The monobloc units, finally, need the installation on the perimeter walls of the house.
As for the indoor units, however, there are the following types: wall-mounted, floor-mounted, wall-mounted, wall-mounted, flush-mounted, flush-mounted (1-way and 4-way) and column-mounted.
 
05
FIXED AIR CONDITIONER CHARACTERISTICS
The fixed conditioner is characterized by two distinct components: the outdoor unit, which comprises the compressor, and the indoor unit comprising the condenser and the evaporator. For large rooms it is possible to connect more than one indoor unit to a single outdoor unit with adequate power (multisplit).
The multisplit therefore allows the installation of a single external motor that provides all the power needed for one or more indoor units for air conditioning; all this, obviously respecting the installation quotas and / or the pipe sizes as described by the single producers.
 
06
PORTABLE AIR CONDITIONER CHARACTERISTICS
The portable air conditioner consists simply of a single element, resting on wheels, on which the compressor, the condenser and the evaporator have been mounted directly. A portable air conditioner can be the perfect solution to lower the temperature in small rooms.
This type of conditioner is not very noisy, but certainly it is more than fixed (or split); moreover, for its correct functioning, it is necessary to keep the window open to allow the pipe to expel hot air. The biggest advantage is certainly that it can be moved easily and without difficulty where the need arises.
 
 
07
HOW DO YOU MEASURE THE PLANT POWER?
The power of an air conditioner, whether fixed or portable, is measured in frigories (Frig / h) or BTU (British Termal Unit).
To know the need to refresh a certain environment, it is sufficient to perform a precise calculation by multiplying the cubic meters of the environment to be conditioned by a variable thermal coefficient depending on the geographical position and the type of room.
Other factors that affect the calculation of the requirements are the characteristics of windows and windows (for example, the presence or absence of double glazing), exposure to the sun, the shaded outdoor areas and the number of people and electrical equipment on average within the environment.
Before proceeding with the purchase of an air conditioner, in any case, it is advisable to rely on professionals in the sector in order to request an inspection by an installation technician who will carry out the exact calculation of the necessary needs.
 
08
HOW CAN YOU CALCULATE THE FRESH NEED FOR A LOCAL?
The most common approach for the quick calculation of the indents of a room in order to select the most suitable air conditioner is to obtain the volume and multiply it by a value ranging from 20 to 30 W / m3. Unfortunately, sometimes this can reserve unpleasant surprises ranging from insufficient cooling to poor dehumidification if the load was overestimated. It is for these reasons that it is better to contact the professionals of the sector in order to request an inspection by an installer who will carry out a precise calculation of the "fresh" requirement.
 
 
09
WHAT IS THE AIR CONDITIONER FUNCTION?
An air conditioner is an element that essentially has the following 3 functions: cooling, heating (heat pump) and dehumidifying.
In general we remember that, in its operation, a modern air conditioner uses a completely inert gas (R410A or R32), but that until a few years ago a gas (R22) was used which then turned out to be harmful to the environment, a reason for which they have finally prohibited trade.
Although the current models are enormously more efficient and environmentally than those of the past, if you have an old air conditioner, you can continue using it until an irreparable failure occurs or the gas runs out.
As for the heating function, today almost all the fixed air conditioners are heat pumps, ie capable of introducing hot air as well as cold air into the air-conditioned environment. In fact, it is advisable to use the heat pump instead of a heating system powered by other heat sources as energy consumption is reduced.
Regarding the dehumidification function, it must be considered that often the feeling of heat is dictated in part by the presence of moisture in the surrounding environment. In these cases, activating the "dehumidifier" function of your air conditioner is the best choice as it allows you to break down the afa without sudden changes in temperature (notoriously harmful for the elderly and young children), while ensuring reduced energy consumption.
 
11
ARE EXISTING CONDITIONERS WITHOUT OUTDOOR EXCHANGE?
On the market there are air conditioners without air exchange with the outside: they are water-cooled air conditioners. All the other types of air conditioners, in fact, need to expel hot air outside the cooled environment, whether it be fixed air conditioning systems or portable air conditioners.
 
 
12
THE ENERGY CLASS OF AN AIR CONDITIONER
Every air conditioner on the market must now clearly state its own reference energy class in a clear indication.
On a scale of 7 classifications, the energy consumption of an air conditioner, which ranges from letter A to letter G (with increasing consumption values), is shown on the ErP energy label; in addition, for each class there are three sub-values that provide further indications on the energy efficiency of the machine, so as to orient the purchase even more consciously.
 
13
NOISE OF AN AIR CONDITIONER
An important characteristic of each air conditioner is its noise level.
Today there are several models on the market that guarantee low levels of noise during operation that, in some cases, can be further reduced by a special "silent" mode that allows the achievement of an almost total silence (something to be taken into consideration especially for installations for domestic use, an environment in which excessive or annoying noise could cause disturbance for oneself and the neighbors).
