How to choose the right air conditioner

To the choice of such a complex instrument, an indispensablein the summer, it is necessary to approach as thoroughly as possible. What should be emphasized and how to find the one that will satisfy your desires and needs? First, you need to decide which room will be air-conditioned. There are nuances for kitchens and nurseries, bedrooms and living rooms, offices and spa. For example, you can not install the air conditioner directly above the workplace or sofa, otherwise you will have to change the furniture to avoid catching cold. Blinds should always be pointed only upwards. It must be borne in mind that the air conditioner reduces the level of humidity, so it's not necessary to keep it on even during the most hot day. What is an air conditioner This device,designed to cool the air in the room. Inside, the air conditioner is not such a complex structure: its main components are a compressor, a fan, a condenser, an evaporator and a thermostatic expansion valve, all together they form a refrigeration circuit. Gaseous freon first enters the pressure compressor and then the substance moves to the radiator. Condensation takes place here, and then the mixture enters the evaporator, where room air is also injected. And in its place the cold rushes and the temperature in the room drops noticeably. It is important to understand that the air conditioner does not take air from the street, but continuously drives the air in the room. To provide the room with fresh oxygen, it is recommended to ventilate the room or use devices for supplying it from the street. How to choose There are floor-standing air conditioners,mobile, window, inverter and split systems. The first three, of course, no one will buy now because of their size and noise. Usually, it is split systems that are installed in the room, which consist of two blocks - outdoor and indoor, which fit into any interior. Thought can and simply must go further - for the whole apartment, you can make a multisystem tied to one external block. Examples of these can be found on the website, for example, of the Mitsubishi company that manufactures these systems. And together with the control panel and the timer, the temperature in the premises will be regulated with an accuracy of a degree, allowing you to set the most comfortable conditions. But when installing such systems, do not forget about supply ventilation and methods of drawing fresh air, as already mentioned earlier. Air cleanliness issue Air recirculation ina room with its subsequent cooling can negatively affect health, therefore, it is necessary to consider an option with a constant saturation of the internal atmosphere with air from the street. Constantly opening windows is not an option if they face a noisy avenue or a gas-polluted area. Here a breather will come to the rescue - a device that provides an inflow of purified air with the possibility of heating it, and also displaces unpleasant odors. But it does not cool, since it does not have a compressor inside. Power selection Air conditioners differ inpower, which varies from 1 to 5 kW. At the same time, the minimum is quite capable of providing a room with an area of 10 square meters with cool air. But you need to understand that there is no scale that would correlate the size of the room and the power of the device. All calculations are made by the specialists of the selling company. They take into account not only the area, but also the geometry, the arrangement of windows and furniture, wall and ceiling materials, and much more. Noise level In the bedroom, study or nurseryno one will install too noisy units in the room. But until the air conditioner is turned on in complete silence, one can only guess about its level of sound vibrations. If the instructions specify a range of 15-40 dB, then it is pretty quiet. External blocks of split systems and mobile air conditioners are 2-3 times more noisy. An important point: it is necessary to clarify this characteristic at an average or even maximum power, because the manufacturer cleverly focuses only on the lowest intensity. What about the design?You should never select an air conditioner based on its appearance alone. Underneath it can hide a primitive set of functions, while a completely nondescript model suddenly takes a hundred points from the first. White is a classic for air conditioners, but if you wish, you can create anything you want with its appearance. The question of price This point is not only related tothe cost of the air conditioner itself, but also installation services and even payment for electricity in the future. Therefore, when choosing, it is necessary to carefully study the characteristics of the models of interest, the difficulties that may arise during the installation, as well as the energy efficiency of the equipment itself (preferably class A, A +, A ++) and the magnitude of inrush currents. Ideally, for the latter, a value of 1.9 A. Availability of unnecessary options Air conditioners can alsobe burdened with a whole set of functions that you will never need. These are heating, ventilation, and automatic selection of the cooling program, ionization, filtration, motion sensors, night mode, and so on. If some options are not needed, why overpay for them? Editorial opinion: - Selection of an air conditioner is not easy. Having considered all of the above factors, you can formulate certain criteria for yourself, according to which the equipment will be selected. But the main question is - how often will you use it?
