The quietest air conditioners

The LG Eco Smart series of smart air conditioners was born in 2019. The most popular model in it for servicing residential premises with an area of up to 25 m2 is the "nine" with the index PC-09SQ.

The split system works under the supervision of a double inverter compressor of energy efficiency class A++. It cools the air in the room noticeably faster, makes a minimum of noise and effectively handles with maintaining the set parameters of the microclimate. Jet Cool technology is designed to accelerate the creation of comfortable conditions in the hot summer heat — cooling the indoor air in just 5 minutes. During the off-season, the operation of the air conditioner is possible up to a temperature of -10 °C outside the dwelling.

So that drafts do not "walk" around the perimeter of the serviced area, the LG Eco Smart PC-09SQ has a "Comfort PLUS" blowing mode. It redistributes the movement of air masses to cover all dead zones, avoiding direct streams hitting people. Another proprietary feature of the air conditioner is real—time monitoring of energy consumption by Active Energy Control. The power consumption in it can be set independently between the values of 40, 60 and 80% with just one tap on the button on the remote control.

An important criterion when choosing an air conditioner for a bedroom or a nursery is the low noise level of the indoor unit. And indeed, LG Eco Smart PC-09SQ "makes noise" in the night mode of blowing no louder than 19 dB. And it is also offered to "steer" all the processes of the split system from a smartphone through the SmartThinQ application. It also provides access to the "smart" diagnostics of air conditioner units. The 10-year warranty on the inverter compressor strengthens the model's position among peers.

The blue-red "C&H" symbols on the air conditioning units are recognizable from afar. In this simple abbreviation, the name of a popular player in the arena of climate technology, Cooper & Hunter, is encrypted.

Under the wing of the Nordic line, the brand's inverter split systems are combined with an eye to working in a wide range of outdoor temperatures. Thus, the Cooper&Hunter Nordic Evo NG CH-S09FTXN-NG model remains fully operational in temperature ranges from -25 °C to +52 °C. When working for heating, the air conditioner demonstrates high indicators of "fuel" efficiency — the energy saving class of the unit in this mode is marked A+++. Well, with the cooling of air masses, the model also handles with a solid "five".

Freon R32 with improved thermodynamic properties "flows" along a route up to 20 m long between the blocks of the split system. Commands to the air conditioner are given from the remote control, in the case of which the temperature sensor I FEEL is "planted". The sensor monitors the temperature near the household locations and transmits data to the split system microprocessor for more accurate maintenance of the specified microclimate parameters.

The crown "feature" of the model is support for remote control from a smartphone or tablet on Android and iOS operating systems. However, the stability of the connection of the air conditioner with mobile clients over the Wi-Fi network leaves much to be desired. The air conditioner was loaded with a warm start function (in case of cold weather), self-cleaning and defrosting systems of the external unit, as well as a quiet night mode of rotation of the fan blades of the room module (no louder than 19 dB). As a result, we have a balanced climate unit at an affordable price.

The inverter air conditioner hails from the Land of the Rising Sun Hitachi RAK-25RPC/RAC-25WPC is designed to serve in the premises of a home or office predestination with a "square" of up to 25 m2. For the maintenance of just such an area, there is enough strength in the brushless drive "under the hood" of the split system.

The model works for the benefit of creating and maintaining coolness in the hot summer heat, heats the air during the off-season and winter, dries excessively moist air masses and circulates air flows, as they say, idling. The temperature range of the air conditioner is outlined in a wide range from -15 °C outside the monastery to +43 °C.

The climate system has a turbo cooling mode (for the first 20 minutes it works at maximum power), maintains comfortable microclimate parameters "on the machine", ensures that the temperature in an unheated room is maintained at a level not lower than +10 °C (standby heating mode) and has a quiet night blowing programme in the bins. The noise from the rotation of the fan blades of the indoor unit in the latter case does not exceed 19 dB (quieter than a human whisper).

A separate line of the user will be pleased with the remote control device with a large informative screen and a scattering of all kinds of buttons. With its help, you can set a programmable timer for a week ahead (up to 6 on/offs during each day of the week), control the position of vertical and horizontal blinds, and the remote control also displays indoor air temperature, energy consumption and alarms on the display.

As an air purification system, Hitachi RAK-25RPC/RAC-25WPC uses a Wasabi Nano Titanium filter, on the surface of which wasabi particles with powerful antibacterial properties are applied. The filter makes the air in the room cleaner and neutralizes the lion's share of microbes when it is "distilled" through the "insides" of the split system. With such data, the model fully fulfills every penny spent.

The "Premium" brand is not molded anywhere. It is honored to carry the best products in the class, in particular, the Mitsubishi Heavy Premium SRK25ZS-WB split wall mounting system.

The air conditioner is destined to serve for the benefit of the comfort of households in residential premises with a "square" of about 25 m2. The model cools the air on hot days, provides warmth in the winter season (at temperatures up to -15 °C outside the window), dries excessively moist air masses and operates in the mode of a conventional fan. The energy efficiency class of the split system when working for cooling and heating is indicated by the highest mark A +++.

The heart of the model is a quiet inverter motor that accelerates ozone-safe freon brand R32 through the "veins" of the system. Also, antibacterial and deodorizing filters are hidden in the "insides" of the room unit of the air conditioner. Mechanized drives of vertical and horizontal blinds ensure uniform distribution of air flows around the perimeter of the serviced area.

From the remote control of the device, it is possible to set a weekly timer for the operation of the air conditioner, turn on the standby heating mode (maintaining the temperature in an unheated room at about +10 °C) and quickly switch the operating modes of the split system as a whole. In case of power outages, the model resumes blowing with the parameters "hammered in" ahead of time thanks to the autorestart function. Finally, the self-diagnosis option is designed to identify unit breakdowns in the early stages, during which the fault code of the air conditioner is displayed.

The Daikin Emura family of air conditioners is positioned as the flagship with a focus on high energy efficiency and low noise in operation. The best confirmation of what has been said is the FTXG25L/RXG25L luxury model.

The split system is based on inverter control technology, due to which the air conditioner boasts low energy waste (class A +++), a noise threshold of 19 dB (with night blowing) and a long operational life. The model is resistant to cold up to -15 °C and does not give up positions in the heat up to +46 °C.

The software assets of the split system include auto-selection of the blowing mode, which will come in handy in the off-season and prevents frequent switching between cooling and heating. Also, users of the climate unit will appreciate the weekly timer function and the presence sensor. According to the latter, the air flow is redirected away from people, and if indoors for 20 minutes. there is no one — the air conditioner goes into standby mode.

The elegant indoor unit of the split system is equipped with mechanized drives of horizontal and vertical blinds. And under its "hood" hides from prying eyes a bundle of an air filter and a titanium-apatite photocatalytic filter element. And everything would have been the way for the model, if not for the high cost. However, it is not a sin to pay for a product of the highest class — the purchase of Daikin Emura FTXG25L /RXG25L should be considered as a profitable investment in the creation and maintenance of microclimate parameters perfect by your standards in the monastery.
