Air conditioner operating modes. Air conditioner operating instructions

“Fan” mode, translation into Russian in the air conditioner

Among the air conditioner switches you can find the “fan speed” option. If we translate this word into Russian, we get “fan speed”. The function may also be referred to simply as "fan", which is equivalent to the word "fan". When selecting this mode, you can change the rotation speed of the valves in the unit. If you increase the rotation speed, the air conditioner will cool and heat the room faster. The fan often changes rotation speed, as its operation is automated. The speed is calculated from the difference between the set temperature and the room temperature. The speed can be fixed using the button marked “fan”. As a rule, you can choose three or four rotation speeds.

"Fan" is indicated by a fan symbol.

How does the “Fan” ventilation mode work and what is it for?

After turning on the “Fan” ventilation, the device uses the so-called “shaft” (also known as a fan, also known as a drum with blades), located in the indoor unit. Air is taken from the room, filtered and returned to the room. At the same time, layers of air of different temperatures are mixed and the entire room (apartment) has a uniform “degree”. This is convenient when, for example, the bathrooms are cooler than the living rooms (or vice versa).

This option is also relevant when, for example, a person is sick - a flow of air at room temperature can refresh him. A cold stream can only do harm. If you have small children, this function can also be a life saver. Knowing what the ventilation mode in air conditioners means, it is easier to figure out how and when to use it. The mode is turned on in the following cases:

• when the air in the room is stagnant, you feel that the air next to the radiators is hot, but the heat (or cold, depending on your needs) does not reach the corridors. Cold air collected near the floor, and warmer air near the ceiling; for human comfort, it is better to equalize the temperature;
• There is an unpleasant odor or dampness in the room - this can be eliminated by turning on the shaft. In this case, the air is forced through existing filters (carbon, catechin, plasma, bactericidal and others);
• when the room has the optimal temperature and you just want to be under the flow of air (neither cold nor hot);
• There are sick people or small children in the room for whom cold air is contraindicated, and a flow of room temperature will not harm.

Basic functions and operating modes of air conditioners

An air conditioner is a device for maintaining optimal indoor climate conditions. It is mainly used for cooling, but in addition to its main function, it can perform a number of other tasks. The ability to configure the device in a way that is comfortable for you depends on the operating modes and additional functions.

Basic operating modes of air conditioners:

• “Cool” - cooling mode. Each air conditioner is designed primarily to cool the air mass in the room. Cooling occurs due to the process of converting a substance (refrigerant, freon) from liquid to gaseous state. The minimum temperature that most air conditioners can maintain is 16-18 degrees.
• “Heat” – heating mode. The heating mode is very convenient in the off-season - in autumn and spring, when the central heating does not work and the temperature outside has dropped. In heating mode, the air conditioner turns on when the room temperature drops below the set temperature. Thanks to the operation of the fan, heating with an air conditioner is very effective, since the heat is not retained near the ceiling, but is evenly distributed throughout the room.
• “Fan” - ventilation mode. In ventilation mode, the compressor and outdoor fan are turned off, and the indoor fan runs at the speed set by the remote control. Thus, the air conditioner distributes air evenly throughout the room. This mode is convenient to use, for example, in winter, when warm air from the central heating radiators accumulates at the top and remains cold at the feet.
• “Dry” - drying mode. To reduce air humidity, split systems provide a special drying function without lowering or raising the temperature. Working in this mode prevents walls from becoming damp and mold from appearing in rooms with high humidity. The dehumidifying mode is also convenient for eliminating discomfort during wet weather.

Additional modes:

• " Auto " - automatic mode. In this mode, the air conditioner itself controls the selection of operating mode (Cooling, Heating or Ventilation) to maintain a comfortable temperature.
• " Turbo " - turbo mode. This function of the air conditioner activates the maximum power of the device to cool the room as quickly as possible.
• " Sleep " - night mode. Provides the most ideal conditions for complete relaxation. After turning on this mode, the fan located inside the unit begins to rotate at lower speeds, reducing the noise of the operating device. The temperature can drop or rise by two degrees, depending on the operating mode of the split system (heating or cooling) and is maintained at this level for the time set on the timer. After this, the air conditioner turns off.

Main functions of air conditioners:

• Filtration. All split systems are equipped with a pre-filter that traps dust, protecting the heat exchanger. The air filter must be washed or cleaned with a vacuum cleaner. Many models also provide additional fine filters.
• Setting the temperature. The temperature that the air conditioner must maintain can vary from +16 to +31°C for cooling and heating modes with an accuracy of 1°C.
• "SWING" - regulation of the direction of air flow. When using this option, the tilt of the horizontal blinds changes, which allows you to evenly blow air into the room or concentrate the flow in one direction. In some models, it is possible to adjust the air flow not only vertically, but also horizontally, using automatic vertical blinds (3D AUTO AIR function)
• “SPEED”—adjust the fan rotation speed. The indoor unit fan can rotate at different speeds, accordingly changing the amount of air passing through the indoor unit. Typically the fan has 3 to 5 fixed speeds plus an automatic mode. In automatic mode, the fan speed is selected based on the current and set temperatures - the more the current temperature differs from the set temperature, the higher the fan speed.
• "TIMER" - timer. Using a timer, you can program the air conditioner to turn on and off automatically. For example, it can be programmed to turn on half an hour before you usually arrive from work, etc.

Protective functions:

• Self-diagnosis. During operation of the air conditioner, the microprocessor controls its operating mode, as well as the state of the external and internal units. Each mode and possible malfunction has its own combination of LEDs on the front panel of the indoor unit, from which you can determine the condition of the air conditioner.
• Automatic restart If there is a power failure or electricity loss, the air conditioner will start in the same mode that it was operating before the incident;
• Warm start. This function is provided only for heating mode and allows the indoor unit fan to operate only when the temperature of the indoor unit heat exchanger is already high enough. This eliminates the possibility of cold air entering the room.
• Defrost (defrost) mode. During winter periods, ice forms on the outdoor unit of the split system due to the collection of condensate. The function is designed to remove ice. During ice removal, the indoor unit stops the cooling or heating process.

Additional features of air conditioners:

• Additional air purification. ROYAL Clima air conditioners are equipped with fine air filters. The Silver Ion filter effectively destroys mold spores, bacteria and viruses in the air. The Active Carbone filter is a carbon filter cassette, passing through which the air is cleaned of harmful impurities and odors.
• COLD PLASMA. The cold plasma generator device (COLD PLASMA) installed in the indoor unit destroys unpleasant odors and toxic gases in the room. In addition, microorganisms harmful to health inside the air conditioner itself are deactivated. This function is presented in the ROYAL Clima PRESTIGIO and PRESTIGIO EU Inverter air conditioners.
• Ionizer. Thanks to the built-in ionization, the air flow passing through the indoor unit is saturated with negatively charged particles - ions, which clean the air of bacteria, unpleasant odors and create the effect of fresh forest air in the room. In addition, saturation of the air with negatively charged particles improves productivity and helps fight lethargy and drowsiness. The ionization function is present in ROYAL Clima GLORIA air conditioners.
• 3D AUTO AIR. Air conditioners with 3D AUTO AIR technology are equipped with automatic horizontal and vertical blinds that ensure uniform distribution of air flow in the room. Adjust the optimal position of horizontal and vertical blinds using the control panel and enjoy maximum comfort without drafts or stagnant areas. This function is presented in the ROYAL Clima split systems of the GLORIA, PRESTIGIO, TRIUMPH Inverter, TRIUMPH GOLD Inverter and PRESTIGIO EU Inverter series.
• I FEEL. The air conditioner responds to the temperature, which is determined by a sensor in the control panel. It is enough to place the remote control in the right place, the split system will monitor the climate in this area. This function is presented in ROYAL Clima air conditioners of the GLORIA, VELA, VELA Inverter, VELA GRANDE, SPARTA series.
• Wi-Fi / Wi-Fi Ready. Thanks to this function, you can freely control the climate in your apartment using your mobile phone (on the iOS or Android platform), even when you are outside your home Wi-Fi network. The ROYAL Clima assortment includes a series with a built-in Wi-Fi module - ROYAL Clima SPARTA, as well as series prepared for connecting a Wi-Fi adapter (Wi-Fi ready) - TRIUMPH, TRIUMPH GOLD, PRESTIGIO, TRIUMPH Inverter, TRIUMPH GOLD Inverter and PRESTIGIO EU Inverter.
• Work at low temperatures. Household split systems as standard are not designed to operate for cooling at subzero temperatures. For on/off heating, split systems operate at outdoor temperatures from -7 ° C, ROYAL Clima inverter split systems can operate for heating from -15 ° C, and SPARTA series inverter split systems from -20 ° C. There, where it is necessary to cool the air at any time of the year, for example in server rooms, air conditioners are additionally equipped with a so-called “winter kit”, which allows them to operate at very low temperatures (down to -40 ° C). All semi-industrial split systems ROYAL Clima are already equipped as standard with a winter kit down to -15 ° C.

Do not confuse the “Fan” ventilation mode and ventilation

Ventilation involves the flow of fresh air from the street. But with traditional air conditioners, air does not come from the street! The air is taken directly from the room. At the same time, the room temperature remains the same. This “FAN” VENTILATION mode is found in almost all modern air conditioners.

The most “advanced” models have special devices capable of taking air from the street, i.e. carry out VENTILATION. The outside air in them undergoes thorough filtration, after which it enters the room. Such devices are very expensive and extremely rare.

An example of the implementation of a ventilation and ducted air conditioning system

The following is the most commonly implemented option for supplying air from the street through a ducted air conditioner. The object is a city apartment on two levels. On the project - one of the floors. Three sheets, excerpts from the project:

Project of small supply and exhaust ventilation in an apartment

General plan for ventilation and air conditioning of the apartment

If you look closely, you can see how the “green” (air supply) line of the air duct, in addition to ending with the ceiling diffusers, goes into the adapters of the ducted indoor units. This is the answer to the most popular request about combining systems into one.

Below are a couple of photos from this object, how it was implemented (the first stage). Air ducts without thermal insulation are an air intake that is to be cooled and distributed throughout the premises. On the indoor units there are adapters to which the air ducts themselves are connected.

There are no photos from the second stage yet, but you can see what the object usually looks like after the renovation is completed in a couple of photos below:

But if you still want to get acquainted with the cost of a duct air conditioner, and not the system as a whole (let’s call it asking the price), then below we have presented several of the most popular models installed on sites. These are inverter split systems: one external and one internal unit, although the system can have many variations. One of the most common is a multi-split system with ducted indoor units, that is, one external unit capable of supplying refrigerant to several indoor units operating independently in different rooms. Still, contact our engineers! Creating such systems is our job!

Don’t rack your brains, don’t look for a “model with fresh air supply.” Just formulate your terms of reference, send us your planning solutions, our ventilation department managers will be able to prepare an adequate proposal for you and will try to implement your ideas if technically possible. Full-time designers, facility managers, qualified installers and our own service center: the entire structure is involved in the successful implementation of a facility of almost any complexity.

Do not confuse the “Fan” mode and the “Fan” speed control buttons

The “Fan” mode on the air conditioner does not perform the functions of heating or cooling the room. It simply creates air flow like a fan. This same fan has several rotation speeds. Therefore, on air conditioners it is necessary to distinguish:

1. “Fan” mode, which is indicated on the remote control display by the inscription “fan” or by an icon in the form of a fan. Modes are switched with the “mode” button;
2. The fan speed adjustment button, which is also labeled “Fan” or “Fan Speed” or “Speed” ON ALL AIR CONDITIONERS. It can be used to change the fan speed:

The rotation speed button does not turn on the ventilation mode itself!

The first problem is the overestimated productivity of KKB

KKB is selected for outdoor air parameters (temperature +28 °C and humidity 45%). But the customer plans to operate it not only when it is +28 °C outside - the rooms are often already hot due to internal heat excess starting from +15 °C outside. Therefore, the controller sets the supply air temperature at best to +20 °C, and at worst - even lower. KKB provides either 100% performance or 0% (with rare exceptions of smooth control when using VRF outdoor units in the form of KKB). When the outside air temperature drops, the KKB does not reduce its performance, but in fact even slightly increases it due to greater subcooling in the condenser. Therefore, when the air temperature at the inlet to the evaporator decreases, the KKB will tend to produce a lower air temperature at the outlet of the evaporator. Using our calculation data, the outlet air temperature is +3 °C. But this cannot be, since the boiling point of freon in the evaporator is +5 °C. Consequently, a decrease in the air temperature at the evaporator inlet to +22 °C (or lower) in our case leads to an overestimated performance of the KKB.

Next, the freon “under-boils” in the evaporator, the liquid refrigerant returns to the compressor suction and, as a result, the inevitable failure of the compressor due to mechanical damage.

But our problems don't end there.

How to enable the “Fan” ventilation mode?

Fan ventilation in air conditioners is activated using the remote control. The inclusion algorithm is quite simple:

1. Turn on the device with the “on/off” button;
2. Press the mode selection button several times (usually it is labeled “Mode”) until the fan image or the word “Fan” lights up on the remote control display;
3. We are waiting for the split system to completely switch to the specified mode. While waiting, you can additionally set the tilt of the blinds (usually this is the “Swing” button), set the fan rotation speed (using the “Fan” or “Fan Speed” or “Speed” buttons).

Since the ventilation mode in traditional air conditioners does not supply fresh air from the street, the use of this function does not exclude the banal ventilation of the room.

Are household appliances capable of supplying air from the street?

To bring cooled fresh air into the room, a new generation of devices has appeared - air conditioners. These include:

• 
  some models of Panasonic air conditioners that have a special membrane in the unit. It allows you to maintain a constant flow of oxygen;

• the well-known brand Mitsubishi Electric has put up for sale a system that, in addition to supply ventilation, has additional filtration;
• climate market leader Daikin has released models with humidification and air flow;
• Hitachi has similar developments, but so far in models with low productivity.

They differ from classic “splits” by the presence of an additional air duct (hose) , which is equipped with various devices for regulating the air supply.

Membrane

The operation of the air duct is regulated by a special membrane, which is “responsible” for the throughput. The required level of oxygen is maintained in the room due to its better penetration than particles of other gases.

Modular system

It is an addition to the one already installed in the form of a module, which is a small hood with a fresh air supply. This option has little air exchange and large dimensions, which is a disadvantage.

Conclusion: If you have EXTRA money, then of course you can pay attention to split systems with air supply. But I believe that this option will not have the effect of full ventilation. When choosing an air conditioner for your home or office, traditional “splits” are quite suitable (read a separate article on how to choose them). Nobody canceled the periodic opening of the window for ventilation. Well, if we talk about an industrial or commercial premises, then a separate ventilation system and a separate air conditioning system will definitely be required!

That's all! Good luck!

Fan speed setting

The speed of the fan determines the intensity of heating or cooling of the room. The higher the speed, the faster the required temperature conditions are established and the greater the volume of air will pass through the indoor unit. Most split system models are equipped with three operating speeds and automatic fan speed selection. With automatic speed control, the microprocessor can select the rotation speed based on the difference between the set temperature and the room temperature. If the difference is large, a higher speed is selected. In the dehumidification and sleep timer modes, the fan operates at minimum speed.
