How do we choose an Air Conditioner?

The air conditioners provide ventilation and heating for the rooms of the building. Air conditioners are generally easy to install, use and clean. There are air conditioners that have integrated Wi-Fi mode that can be controlled remotely.

The price of an air conditioner will be influenced by its type plus the implemented functions, to which is added the cost of installation.

It is recommended to install air conditioners with authorized companies to ensure their maintenance.

• Depending on how many rooms you need air conditioning, you can choose a split or multi-split device. The single-split system has an indoor unit connected to an outdoor unit, and this is the optimal solution for a room. A multi-split device allows you to have several indoor units connected to a single outdoor unit, ensuring a perfect climate in several rooms in the house.
  Depending on the size of the rooms, the air conditioning units are chosen. The height of the ceiling and the area of ​​the room in square meters are 2 of the factors that determine the required capacity of the units. The unit of measurement for the cooling / heating capacity of an air conditioner is W (Watt). A capacity index of 30-40 W / m3 can be considered for estimating the cooling load (depending on indoor and outdoor temperatures, degree of insulation, occupancy and internal heat release). A capacity index of 40-60 W / m3 can be considered for estimating the heating load. In the data sheets provided by certain manufacturers, the capacity of the equipment is expressed in BTU / h. To make an index conversion per square meter, given that 1W = 3.41 BTU / h, you need to know that you need about 45 BTU / m2 for cooling and 65 BTU / m2 for heating, for a standard space height of 2.7 meters. These values ​​are indicative and are used when there is no specialized project of choice of equipment. For a correct calculation, the glazed surfaces must be taken into account, whether or not there is thermal insulation, the size of the windows, the electrical power of the other electrical appliances or appliances that still emit heat in the room, including the lighting system. These calculations are made by specialized designers (installation engineers)
• How do we decide where the indoor unit and the outdoor unit are located? The architecture of the building is very important for choosing the configuration of the air conditioning system. Depending on the architecture of the building, the position of the outdoor unit / units is decided and the length of the refrigeration route is determined. The closer the outdoor unit is to the indoor unit, the simpler and more efficient the installation. The most important aspects when it comes to the location of the outdoor unit are ensuring a good circulation of outdoor air on the heat exchanger and the possibility of draining the condensation produced by the indoor unit. Therefore, it is not recommended to mount the outdoor unit indoors or indoors. A correctly selected and installed system is essential in ensuring thermal comfort through uniformity of temperatures, lack of air currents and low visual impact of the installed equipment. Depending on the design of the room, you will choose the right type of indoor unit. Thus, you can consider a standard indoor unit (with wall mounting), a floor unit (which is mounted a few inches above the floor) or one that can be hidden in the false ceiling of the room, the air conditioning is made by pipes and grids. The most commonly used, especially in homes, are wall systems, which have the advantage that they are very easy to install, have convenient prices and do their job very well in the spaces where they are located. For a uniform distribution of air throughout the room, it is recommended that the indoor unit be positioned at least 10 cm away from the ceiling. The most modern models use technologies to identify the presence in the room, which allow the use of the equipment without creating discomfort, so you do not have to worry if the device is positioned behind or in front of the desk. However, not all systems on the market are equipped with innovative technology and functions to evenly air-condition the room. Therefore, they must be strategically installed in certain places for optimal room temperature distribution.
• In which room is it good to mount the indoor unit of the air conditioner, in the hallway, in the living room, in the office or in the bedroom? For maximum efficiency, the best option would be a device in each room on which you want to be air-conditioned. Placing a higher capacity system in the hallway will not result in air conditioning the whole house and will not be able to maintain a uniform temperature in each room. In this case, the air conditioning system will work excessively to cool / heat the air in the hall and there is a possibility that the appliance will work for more hours than would be necessary to reach the set temperatures, thus resulting in electricity consumption. much higher.
• The most important features of the air conditioner: Comfort is determined not only by the temperature of the indoor air, but also by the humidity level, the speed of the air in the room, the quiet operation and the optimal distribution of air. At the same time, the functions of air filtration against allergens, bacteria and viruses, plus the low power consumption and the possibility for AC devices to be easily controlled from your smartphone or tablet, are important aspects to consider. Electricity consumption is important when choosing air conditioning equipment, so consult the system data sheet and consumption information to see if your home electrical installation can withstand such consumption. It should be noted that class A +++ air conditioners are the most energy efficient. In the long run, high-efficiency equipment, although more expensive, leads to a lower investment and operating cost than cheaper but less efficient equipment. A higher price, for a product that will consume less, means, in fact, long-term savings, as the investment will pay off over time. It is important that both the indoor and outdoor unit have a low noise level. If the impact on the interior is on the user, the noise produced by the outdoor unit reaches the neighbors and there are clear regulations that set the maximum ambient noise limits at the property limit. The noise level indicated in the technical data of the equipment is the one measured in ideal laboratory conditions, while in the real installation conditions, this level becomes higher. Avoid mounting units in corners or indoors, such as courtyards with short distances from opposite and collateral walls. In order to reduce the transmission of vibrations of the outdoor unit to the building structure, it is very important to follow the installation instructions mentioned by the manufacturer in the installation manual.

Well-known manufacturers of air conditioners: Toshiba, Mitsubishi Electric, Panasonic, Daikin, Hitachi, Gree, Midea, Samsung, LG, Aux, Bosch, Haier.
