Proper use of a split system: operation of equipment + care tips

Split system maintenance - basic recommendations

Using practical recommendations, each owner of a ventilation device will know how to service the air conditioner himself?

Regular maintenance of air conditioners consists in cleaning the ventilation structures in the external and internal blocks of the device.

The internal and external blocks of the device work on the principle of a vacuum cleaner, a huge amount of dirty air passes through them. After some time, the dust that has settled on the filters and drainage completely clogs them, which leads to malfunctions in the split system.Therefore, it is recommended to regularly clean each unit of the ventilation system.

The reason for the poor performance of ventilation equipment may be an insufficient amount of freon (coolant), as a result of which the compressor is under strong pressure and the productivity of the air conditioning system is sharply reduced. Full maintenance of split systems should be carried out at least three times a year.

During operation, the owner needs to pay attention to the correct operation of the device. If the device does not cool (heat) the room well, then it's time to clean or check it;
Checking the split system is also necessary if warm air comes out of the device during operation, or there are signs of freezing of the radiator of the indoor unit

The need for service is also evidenced by an unpleasant odor emanating from the device during its operation;
To prevent malfunctions in the air conditioning system, you must maintain the recommended temperature. It is worth noting that most air conditioners cannot function properly at too low temperatures. Remember that ventilation equipment fails faster if it works at maximum mode;
It is imperative to regularly clean the filter of the indoor unit. Thanks to this element, the fan heatsink is reliably protected from dust. If the operation of air conditioning equipment is carried out in dusty rooms, then experts recommend installing gaskets in the indoor unit that provide high-quality filtration;
To effectively clean the filter, it is necessary to rinse it under a small stream of warm water.Masters recommend this procedure regularly;

If the device has been used incorrectly, fluid may leak from the drainage system. Improper use often leads to a deterioration in heat transfer and the appearance of frost on its surface. For this reason, it is necessary to constantly ensure that the operation of the air conditioner is carried out only with a filter;
A preventive check of the air conditioner is carried out twice a year, in a specialized service department. It includes full service of internal and external blocks of the device.

Note that full maintenance of the split system is possible only in a special service center. The owner of the air conditioner can only wash and clean some parts and structures of the ventilation device.

Basic settings

If installation and maintenance is best done by qualified personnel only, then the usual setting of convenient parameters can be done independently. To do this, it is worth studying the provisions discussed in the article.

There are two basic rules by which you can master the heating and cooling functions. These include:

• No big contrast between temperatures. Do not create a strong temperature difference between the room and the street. If you go out of a cool room into a street where there is a terrible heat, there will be a detrimental effect on health;
• Economy while creating comfort. Most air conditioners are equipped with a special mode that saves energy by not allowing you to use an increased amount of electricity.

Each mode is configured individually, which allows you to adjust the device just for you.This brings the air conditioner to the optimal mode, the rational use of all possibilities. You can also create custom settings yourself.

Turning on the heating

Before setting the air conditioner to heating mode, you need to make sure that the temperature of its operation is within the working range, otherwise the system may fail. Undoubtedly, different manufacturing companies (for example, LG, Samsung or General) produce largely different models, but still there is a certain universal model for turning on heating:

• It is necessary to turn on the device (power button, signed as "On").
• Next, press the “Heat” key, which means “warmth”.
• If this button is not present, there may be other options: “Mode”, or any other buttons, under / above which icons such as “sun”, “drop”, “fan”, “snow” are drawn. If none of these buttons is present, it means that the system is not capable of heating.
• If the "Mode" button is present, you need to press it several times until the "sun" or the signature "Heat" is displayed.
• With the help of the switching arrows or the "+/-" buttons, you will have to set the comfortable temperature.

After all this procedure, the fan will turn on, and after five (maximum ten) minutes, warm air is generated, heated to the temperature previously set by the user. Some remote control models may be configured differently - before setting up, it is recommended to read the instructions.

Nuances of operation

Modern models of air conditioners are quite complex household appliances, the setting of which requires compliance with basic rules.

1. It is necessary to clearly select the power of the product depending on the volume of the room: in regions with a very hot climate, it is necessary to install systems with more power, with improved characteristics of the cooling mode.
2. Always correlate the operating mode of the product with the weather conditions outside.
3. In order to prevent the occurrence of any colds, it is necessary to fine-tune the equipment in the cold mode.
4. Carry out regular maintenance - these activities will allow you to ensure the normal operation of the product, and the whole family a safe and comfortable microclimate.
5. Installation, maintenance and repair of equipment should only be done by professionals.

Climate systems can be installed in any premises, regardless of their configuration and dimensions, because modern technology copes with the task without any problems. The user must only follow all the rules and recommendations voiced in this article.

Problems with the functioning of the air conditioner

This issue requires detailed consideration if you do not want to run into problems during configuration. In order for the air conditioner to work for a long time without any breakdowns and failures, you need to follow some rules during its operation. Experts recommend that you carefully monitor the slightest deviations in work in order to avoid serious consequences.

Causes of problems:

• Deviations from the established maintenance schedule. Regularly you need to use the help of specialists who will diagnose and identify problems, if any;
• Small amount of refrigerant.It is with its help that heating or cooling is performed. The amount of this substance must always be in the norm, otherwise the work will not be effective;
• Frequent activation of the maximum work mode. Turbo mode consumes a lot of device power, which gradually disables equipment;
• Neglect of the provisions of the instruction, which leads to the failure of the parameters;
• Breakage from mechanical impact.

If you follow all the instructions and tips, the air conditioner will last a long time without any deviations from proper operation. Clean and flush your split system regularly to keep dust and dirt from clogging the parts.

How to turn on the device correctly

Before switching on, you must:

1. Check for filters in the housing.
2. Make sure the duct grille is free.
3. Clean the space around the device as much as possible.

Further adjustment of the air conditioner concerns the operating system and work with setting modes.

Designations on the display PU

There are two options for starting climate technology - from the remote control and using buttons on the body devices. Usually the buttons are signed in English, so you should look at the meaning in the instructions.

On the control panel, in addition to turning on / off, you can change the operating modes, adjust the temperature, and set elementary commands. Depending on the model and manufacturer, the panel may be located at the bottom or at the top. The "start" button is clearly marked. Modes are selected using the "mode" button. The smart display will show the actions being performed. The condition for quality work is the fulfillment of the requirements specified in the manual attached to the purchase.

Brief instruction of PU air conditioner:

• ON / OFF button - start and stop the climate equipment.
• The "▲"/"▼" buttons adjust the heating and cooling.
• The "MODE" button allows you to select the mode.
• Button "FAN SPEED" to control the speed of rotation of the cooler.

Switching on the heating mode

Some models of air conditioners - inverter air conditioners - can heat the room even in winter, at fairly low sub-zero temperatures.

When the heating mode is turned on at the beginning, the fan may operate for 3~5 minutes to prevent cold air from blowing in while the air conditioner is warming up. Since the air conditioner heats the room by extracting thermal energy from the outdoor air, its heating capacity may decrease if the outdoor temperature is extremely low. Use an additional heater in combination with the air conditioner if you feel that the air conditioner is not heating enough.

In Heat mode, the air conditioner will heat the room. You can set the temperature and fan speed to feel the operation of the heating device in the cold season.

What temperature to set

An example is the following: the temperature outside is 35˚C, if we set the air conditioner to 30˚C, then it will be useful and comfortable for us. But if at this temperature we put the air conditioner at 25˚C, then we will also be comfortable, but less useful. It is not a fact that you will immediately get sick, but due to the high temperature difference, the likelihood of harming your body will increase.

It is very difficult to constantly control the temperature on the street, in this case, at least we focus on average temperatures - from 23 to 26˚C. If you are cool, increase the temperature by 1-2˚C, if it is hot, on the contrary, lower the adjustable temperature.

You need to know this: the numbers on the remote control display the temperature that the air conditioner should maintain in the room, and in no case does it show the temperature of the supplied air. For example, if we set 25, then the air conditioner will maintain + 25˚C. For some models, the remote control may show the current temperature in the room.

temperature at night (during sleep). At night, the human body saves heat and gives it less to the environment, so the temperature in the room should be 1-2˚C higher than daytime (about 25-27˚C).

Good to know: Inverter air conditioners maintain the desired temperature very accurately. Air conditioners "on / off" during operation allow an error of 1-3˚C.

Many modern air conditioners have a “sleep mode” function, after activation, which automatically raises the set temperature by a couple of degrees for some time. It works like this: for example, during the day the air conditioner maintains 25˚C, at night before the "lights out" we turn on the "sleep mode". After an hour of operation, the air conditioner maintains 26˚C, after two hours 27˚C. And this temperature keeps until the morning. Thus, at night we did not freeze and had a good night's sleep. The temperature settings of the air conditioner, where there is no such mode, are increased by 1-2 ˚C before going to bed.

General instructions for using air conditioners

The instruction of any equipment begins with recommendations for installation. The quality of installation depends on the efficiency and term of work without breakdowns. Without experience, it is better not to do such work on your own. Professionals will quickly install the equipment, give the owner a certificate of completion and warranty documents.

Important recommendations:

• Do not insert foreign objects between the grilles while the device is in operation.
• Keep children away from the air conditioner during operation and rest of the device.
• To cool the room, set the temperature to 21-23 degrees. If you set the temperature below, you can get sick.
• The continuous pace of work will lead to compressor failure, so it is worth giving time to rest.
• Close windows and doors while the air conditioner is running, protect from direct sunlight.
• Do not operate air conditioning equipment in rooms with high humidity.
• Periodic maintenance of the equipment consists in cleaning the filters. Carry out the procedure every 2 weeks.
• Turn on the device after checking the quality of the network connection and the integrity of the wires.

It is important to know at what temperature you can turn on the air conditioner: for the outside of the split system, the minimum limit is -5; for the inside, the maximum limit is +37 degrees. Restrictions may vary depending on the humidity outside or inside the house

If the humidity is high outside, the minimum threshold should not fall below -2.

The equipment can work continuously for about 6 hours. It is recommended to turn off the air conditioner for a while every 2 hours. The device cannot be started if the housing is warm or hot. The interval of rest and work should be commensurate.

It is not recommended to be in the area of ​​the cooling air flow during the operation of the climate control equipment. The risk of a cold in this case is high even at optimal air temperature.

If the device has not been used for a long period, you need to turn it on in test mode.Even a minimal period of stagnation requires cleaning the filters and the body of the device before starting. For remote control, you can use a smartphone or other phone if there is a connection to the smart home system.

Before starting work, the device must be configured.

Reasons for the failure of the air conditioner

Dirty filters of the indoor unit

Please note that filter cleaning is not included in the standard warranty.
maintenance and must be carried out by the user (as well as changing bags in a vacuum cleaner) in accordance with
the requirements of the operating instructions.

freon leak

To detect a leak it is not necessary to have special equipment. First signs of decline
amount of refrigerant in the system - formation of frost or ice on the fittings of the outdoor unit
(this is the place where copper pipes are connected), as well as insufficient cooling of the air in the room
(The temperature difference between the inlet and outlet of the indoor unit should normally be
not less than 8–10°С). In case of occurrence
similar symptoms, you must turn off the air conditioner and contact the service department to eliminate
malfunctions.

Air conditioning operation in winter

Another feature of household air conditioners is that almost all
models sold in Moscow are not adapted to work in winter, that is, the lower limit
outdoor temperature ranges from -5°С to +15°С for various models. The reason for this seemingly strange
the behavior of manufacturers lies in the fact that, firstly, the same
air conditioners that are supplied to the European and Japanese markets, where the winter is quite warm -
the absolute minimum temperature in Tokyo is -8°C (Climate World magazine,
No. 3, 1999). Second, installation in the air conditioner
all-weather unit, which allows the air conditioner to operate at an outdoor temperature of up to -25 ° C, increases
the total cost by 150 - 200 dollars, which reduces its competitiveness.

The need for an air conditioner that works all year round can arise in two cases. First, when
it is required to cool the room not only in summer, but also in winter, for example, a room with a large
the amount of heat-generating equipment (server rooms, computer rooms, etc.), since the cooling of such a room with the help of supply ventilation will lead to an unacceptable decrease in air humidity. Secondly,
in case of heating with air conditioning in winter. However, this use of the air conditioner is not always
justified, because even being adapted to winter conditions, at an outdoor temperature of -20 ° C,
the performance (power) of the air conditioner drops three times compared to the nominal.

Operation of an unadapted air conditioner
in the cold season, first of all, it reduces the working life of the compressor.
In addition, when the air conditioner is turned on in cooling mode, condensate (water)
generated in the indoor unit cannot
flow through the drain tube to the outside due to the ice plug. AT
As a result, half an hour after turning on, water from the indoor unit will flow directly into the room.

Note that it is possible to adapt any split system to winter conditions. For this, it is embedded
compressor crankcase heater and outdoor unit fan speed controller, as well as
"warm" drainage is installed.

All of the above applies primarily to split systems, but this is also true for mobile and window
conditioners. The main difference is that monoblock air conditioners do not have a regulated freon leak. That's why
periodic refueling is not required for them.

Split system maintenance - basic recommendations

Efficient and economical use

We figured out what the optimal temperature should be maintained by the air conditioner in the summer. Setting up the air conditioner and enjoying comfort is quite simple, however, it can cost a pretty penny. Air conditioning equipment consumes a large amount of electricity.

And if you do not want the electricity bill to increase several times, then you should follow a few simple rules:

1. Curtain curtains. This will protect the room from heating by the sun, which means that less energy will be needed to cool the room.
2. Set the minimum air flow rate. Yes, in this case the room will cool down a little more slowly, but 15-20 minutes will definitely not be critical. Be sure to close windows and doors indoors.
3. Adjust the angle of the horizontal louvers parallel to the floor. In this case, the cooled air will go down and the hot air will go up. This will allow you to quickly bring the room to the desired temperature.

If your model does not have the ability to adjust the blinds, then install a protective screen directly under the air conditioner.

In this case, the air flow will be dissipated immediately, which will increase the efficiency of the air conditioner.

For maximum efficiency, the protective screen should be installed close to the indoor unit. But at the same time, it should not interfere with the movement of horizontal blinds.

The cost of protective screens is small - from 1000 rubles. But you can make it yourself from plexiglass or plexiglass.

Position of horizontal and vertical louvers

• all air conditioners have horizontal blinds (which regulate the flow up and down) are controlled from the remote control. Adjust them in such a way that the airflow affects people as little as possible. Most often, the most effective and advantageous position is the top. In this case, the air circulates perfectly and passes "over the head".
• vertical blinds (which regulate the flow to the right and left) are manually adjusted on inexpensive models. Usually, they are set up once and for all. It is also necessary to find the most favorable position of the air flow. It is safer to adjust them when the air conditioner is off (if manually).

Often one has to observe when minimum temperatures are set in shops or offices, but this does not bring any effect. The problem is that either the power of the air conditioner is calculated incorrectly, or the device needs to be cleaned or repaired.

Good to know: the automatic settings algorithm allows you to maintain average parameters. In this case, the air conditioner itself selects the temperature and speed of rotation of the shaft, focusing on the readings of some sensors. And not always these parameters will be comfortable for you.

For a detailed description of the buttons and their meanings, see this article.

Why are air conditioners needed?

Split system is a system of two blocks, one of which is indoors and the other is outdoors. It is designed to create optimal climatic conditions.

Initially, it is important to determine what functions these devices can perform. These include:

Air conditioning in the room

1. High-quality cooling of the air in the room to the optimum value, and people themselves choose which temperature should be set, since different temperatures can be comfortable for everyone.
2. Space heating is also included in the functions of modern and high-quality products, and this function is usually used in winter, since it can be used to supplement standard heating with additional heating from the device.
3. Household air conditioners, which are usually installed in residential apartments, can additionally dehumidify the air, which is important for many people for whom being in high humidity conditions is considered not very pleasant and even dangerous to health.
4. Modern appliances are equipped with numerous sensors, due to which the equipment works in automatic mode, so it turns on only when necessary, namely when the temperature in the room reaches the maximum allowable value.

5. Air filtration, as a result of which the air in the room is effectively cleaned of pollution and dust, which has a beneficial effect on the well-being and even health of people.

6. Also, many air conditioners for an apartment can be supplied with other functions. Today, the indoor units of split systems are usually created in an unusual and rather attractive appearance, and you can choose an element that fits perfectly into a particular style of the room. They can also have a backlight, and their control is easily performed using the remote control.

Conclusions and useful video on the topic

How to use the conditioner correctly:

A properly tuned air conditioner will create comfortable temperature conditions in the room.In this case, it will not be possible not to worry about the fact that someone will catch a cold.

However, more complex manipulations with climate equipment, for example, installing a winter kit, should be entrusted to specialists. In this case, you will be sure that everything is done correctly, and your air conditioner will not fail prematurely.
