In the modern world, a person is surrounded by innumerable sounds. Being at home, everyone wants to enjoy peace and quiet. Air conditioning in the house or apartment - a thing, of course, very useful, sometimes even necessary, and it should be chosen, not only from the functionality and appearance. The air conditioner should gently cool the air in the room, and do not interfere with the noise of residents and neighbors.

What is the permissible noise level for an air conditioner in an apartment?
Small home air conditioners are characterized by low noise level, they quickly cool the air in the room, maintain the desired temperature and economically consume electricity. The noise produced by air conditioners is determined in decibels (dB). This value shows the difference in pitch of sounds. Thus, the threshold of audibility is defined by an index of 0 dB. Sounds below 25 dB do not hear the human ear.
When choosing a bedroom conditioner, you need to carefully consider the noise level. The quietest air conditioner must meet the following requirements: the noise of the external unit is from 28 to 54 dB, the internal one - from 26 to 36 dB. When the air conditioner is purchased for a workplace or office, the noise factor is not paramount, and the allowable level is about 45 dB.
After reading the above information, we can conclude: we buy an air conditioner with the lowest noise level, and there is no problem! This is partly true, although in practice it is different. For example, if you compare air conditioners with a noise level of 35 dB and 27 dB, the first can work quieter. The reason is very simple: each air conditioner is equipped with several modes of operation, and each mode has its own noise level. The internal unit of the device is noisy due to the air flowing inside it, which passes through the ventilation, the radiator and the blinds.
For this reason, the air conditioner is noisy "full" only at the lowest speed. However, the air conditioner can not always provide the desired temperature at a low speed - in extreme heat it simply will not be able to cope with its task. Quality air conditioners for the apartment are equipped with the function of automatic switching at different speeds, depending on the temperature in the room. This ensures a comfortable temperature and proper operation of the air conditioner itself.
When choosing an air conditioner for your home, you must first test its operation at all speeds to determine the maximum noise level. Unfortunately, very few buyers are tolerably versed in all the technical properties of air conditioners, so often there is a need to appeal to professionals. And consultants in stores often tell customers only the lower threshold of the device noise. For example, if the noise level of the device is from 25 to 30 dB, then the buyer will be given only the smallest figure of 25 dB.
During operation, any air conditioner generates sounds of different kinds. This and clicks when switching relays, and gurgling, water sounds, etc.
Choose a quiet conditioner for an apartment
If you are annoyed by extraneous noise, you should take a closer look at expensive inverter models that do not have such a disadvantage as the temperature jumps in the work and stopping the compressor. These devices work very quietly and smoothly, the speed is changed gradually, without jumps. The inverter air conditioner produces a pleasant quiet noise, similar to a light breeze. In order to choose the most suitable model, it is recommended to view as many directories of various brands as possible, taking into account the lower and upper noise threshold.
Undoubted leaders in the line of quiet devices are the Japanese models. By the way, they are the most expensive. Also it is necessary to pay attention to the noise level, which is issued by the external unit of the air conditioner. Of course, that the use of air conditioning is advisable only with closed windows, and the noise from the external block of tenants will not bother, but neighbors can be annoying.
Sometimes the Chinese models make a noise so that they can be heard perfectly even through tightly closed windows. And very often the indoor unit works very quietly, but the external noise is thorough.
According to generally accepted standards, the noise level of the outdoor unit of the air conditioner should be 30-60 dB. Some manufacturers go for a trick and indicate the noise level in dBA - the sound pressure. This indicator is slightly lower than the sound power, and from it it is necessary to take about 14 units to get the dB.
Conditioners haier
Quite an interesting novelty. Using the conditioner of this brand, you can completely control the microclimate in your home. In addition, the operation of the air conditioner is possible, not only being at home, but also, without exaggeration, from anywhere in the world. To do this, just connect to the Internet and use the Smart Aircon application, which can be installed on a smartphone or tablet.
Conditioners haier series lightera include models with different capacities: from 9000 to 24 000 BTU (British thermal unit). Thus, it is possible to select a model of the necessary power, suitable for placing a certain area. In addition to the remote control of the air conditioner, it is necessary to note: low noise level, inverter power control of the device, efficient air distribution system, heating and cooling operation. Below we consider all the advantages of air conditioners haier, reviews of which are mostly positive in more detail in order to understand what they like to consumers.
Distance is not a hindrance
Manage home appliances at a distance through special software installed on a smartphone or tablet in our time is not only a fashionable "chip", but also an extremely useful feature. The person receives the most complete control on the microclimate in his home, can change the modes and settings at his discretion. For example, you do not have to wait until the air conditioner reduces the temperature in the room upon arrival - the necessary parameters can be set even on the way from work. Forgot to turn off the air conditioning in a hurry, leaving on a business trip? No problem, it can be done wherever there is a mobile Internet coverage or a Wi-Fi zone.
Air conditioners Haier Lihtera series have the most modern remote control system, through which not only can control the air conditioner from a distance, but also provide the ability to diagnose and troubleshoot the service center. It is important that the manufacturer provided the user with not only standard settings (temperature, mode, etc.), but also deeper. So, there is an opportunity to create an algorithm of work for the "Dream" mode. Taking into account individual preferences, in this mode, the duration and parameters of the temperature change are possible. In addition, you can make the schedule of the device for a certain period, say, for a week. And all this can be done, we will repeat, from any place where there is access to the Network. The necessary software is absolutely free to download from the AppStore or PlayMarket.
Conditioners Haier - use to the maximum
Of course, remotely controlling the air conditioner is convenient. But do not forget about the main task of the air conditioner - quickly and efficiently lower or raise the temperature in the room. Conditioners Haier brilliantly cope with this task, because they are equipped with everything necessary for good work.
Engineers worked perfectly: the air channel was significantly changed, an inverter compressor was installed in the outdoor unit, as well as an inverter electric motor in the internal one. In addition, the impeller was enlarged, and the angle of its inclination was changed, the area of the inlet and outlet sections was increased. All these improvements are necessary first of all in order for the air conditioner to fulfill its main, "weather" task. However, they also contributed to a significant reduction in noise level - Haier split systems with a capacity of 9000 BTU produce noise of only 20 dB (in a special low-noise mode).
Air conditioners of the new generation Haier series lightera automatically support the natural air circulation in the room. This technology is called 3D Airflow - vertical and horizontal flaps work in concert with each other.
Due to the special displacement of the leaflets, the air flow is directed at five corners along the vertical and six - horizontally, spreading at a distance of up to 20 meters and more.
The air conditioner can also operate in the dehumidification mode (necessary for rooms with high humidity). In this case, the device works as follows: the speed of the impeller of the indoor unit is selected automatically, taking into account the difference between the room temperature and the user-specified temperature. As a result, moisture from the air can be removed gradually or intensively - there is the possibility of adjustment.
Turbo mode - the air conditioner operates at maximum power, the desired room temperature is reached very quickly - about twice as fast as in normal operation.
Without irritants and bacteria
New Haier Split systems not only for cooling and heating of premises - people need to breathe clean air, without harmful microorganisms and allergens. To combat these factors, air conditioners are equipped with a high power UV lamp, which is installed in the indoor unit. The length of the UV disinfection is 254 nm. It penetrates into the cells of microorganisms, denying them the ability to reproduce, or completely destroying them.
A fairly important improvement of this brand of air conditioners is the ability to quickly ventilate the room by supplying air from the street with closed windows.
This technology was called O2 Fresh. The air intake device is located at the top of the outdoor unit and is connected to it by means of an air duct and an electric cable. The ventilation mode can be activated using the remote control panel. In this mode, air through the O2 Fresh filter enters the room at a rate of 30 cubic meters per hour.
Allergy is a plague of the 21st century, with additional means of prevention and control with it are always relevant. Haier air conditioners are equipped with filters with reduced cells that hold small dust, insects, and other elements that can cause an allergic reaction. The structure of the filter in the new models has been significantly changed, it has become multilayered: there is a photocatalytic and bactericidal layer that can even detain negligible particles, and a layer with activated carbon will remove unpleasant odors.
Using the built-in generator Nano-Aqua, the water decomposes into ions: H + and O2. During the chemical reaction, a compound H2O2 is formed, which is capable of neutralizing harmful microorganisms. In addition, while in the air is saturated with microscopic water molecules, which favorably affect the upper layer of the skin, moisturizing it.
Specifications of air conditioners haier
In the vehicles of this brand a rotary compressor with inverter control is installed. Its power is 10 times higher than that of conventional compressors, the inverter works with the best efficiency and consumes less electricity.
Evaporators air conditioners are equipped with anti-corrosion coating Blue Fin. This significantly extends the life of the device and saves electricity.
DC motor (inverter). Provides stepless transmission of torque, so that the device economically spends electricity, reduces noise and increases the life of the motor itself.
In the climatic conditions of our country, a very important point is the possibility of using the air conditioner at negative temperatures in winter and during the hot summer season. Engineers took this moment into account, and the haier split systems can operate stably at -10 to +46 degrees. In the cold season, they can be used in heating mode at a temperature "overboard" -15.
In conclusion, it is necessary to note the design, which can be described as "classic with a twist". On sale there are models of the usual white color, suitable for any interior, there are also original colors, for example, golden and silvery (to order).
