Internal units of split systems. The power of the indoor unit of the split system. Installation of the indoor unit of the split system

Today apartments, private houses and offices are often equipped with split systems. This is especially true for urban residents, because in these conditions the weather changes quite often, and it is not always possible to make the indoor climate comfortable with the ventilator, because from the outside come exhaust fumes, dust, and with them noise that interferes with life.

If you do not want to freeze in cold weather and suffer from the heat of summer days, you should buy a split-system, with which you can create the most comfortable conditions for living in the house. But in order for the system to be truly effective, it is necessary to determine the power, as well as correctly install the indoor unit. This will be discussed in the article.

Selecting the indoor unit by power

The indoor units of the split systems are selected taking into account the main parameter - the capacity of the equipment. To date, we know the ratio, according to which, 1 kW of power of the device will be enough for 30 m ^{3 of the} room. If we take into account the area of the room, then the same 1 kW of power will be needed to cool 10 m ² .

This parameter is used by private consumers and specialists who are faced with the choice of the device described. However, this ratio can not be called an accurate example of the calculation of power. If you want to be sure of a choice, then additional factors should be considered. Among them, it is necessary to highlight the location of the indoor unit.

It is important to pay attention to the appointment of technology, as well as the number of rooms in the apartment or office. The indoor units of the split-systems are selected also with additional equipment in the room, which is capable of securing thermal energy during operation. Special attention is paid to windows, which play a huge role in cooling the home. One important factor is the number of people who can be at the same time indoors.

If we examine each factor in more detail, it is worth noting that the location plays an important role. For example, for a bedroom, equipment with a floor unit, which produces a strong noise, is not suitable. It is important to take into account the purpose, because some types of technology can only work for cooling, and there is no heating function in them. But the first version of the equipment has an important advantage, which is expressed in low cost.

Accounting for additional factors

Do not neglect the requirement that it is necessary to take into account equipment such as a cooker, electric kettle or computer. All these devices are additional sources of heat, which necessitates the choice of a split-system technique with more impressive power. The internal blocks of the split systems are selected, as noted, with the windows. Especially this factor refers to rooms with ordinary wooden frames without double-glazed windows. Through them, in summer, warmth enters, and in winter cold air penetrates. Experts recommend paying attention to the number of people, because a human body can produce heat equal to 100 watts. Therefore, it is necessary to compensate for this source of thermal energy.

Preparation of tools for installing a split system

If you decide to do the installation of the indoor unit of the air conditioner yourself, you need to stock up a certain set of tools, among them:

• Perforator;
• Valve fender;
• Pipe cutter;
• A set for expanding the tubes;
• scouring;
• Bicycle hand pump;
• Vacuum pump;
• Phase indicator;
• Manometer;
• Tester for electrical work.

When installing the internal blocks of split systems, it is important to prepare the drill bit, after all, the master has to make a hole in the main wall. If it is concrete, then it will be necessary to have an armature detector, because if you get to the bar, you have to make a new hole. When installing, it is forbidden to cut the refrigerant pipes with a hacksaw, the pipe cutter is suitable for this purpose. Otherwise, there will be copper chips left in the gap, which will damage the compressor.

Installing the indoor unit

To install a split-system in an apartment, it is necessary to be guided by technology, which provides for the first stage of determining the location for the equipment. Next, it is necessary to lay electrical wiring and install an outdoor unit. A hole is made in the wall for communications, then pipelines are prepared and laid.

The specialist will have to install electrical connections, and then check the system for leaks. It is evacuated and filled. Now you can connect the power supply and test the equipment. When the indoor unit of the split system is installed, it is additionally necessary to isolate the interconnector harness. A hole is closed in the capital wall, and the wall is decorated.

Selecting the location for the indoor unit

Choosing a place for this component, it is necessary to pay attention to the areas that can not be used for such work. Installation of the indoor unit of the split system can not be conducted over radiators and other sources of heat. Do not place the structure behind curtains, curtains and curtains, as well as create other obstacles to the flow of air.

Do not place the device even in rooms where there are sources of electrical interference, here include induction and microwave ovens, power tools, and also electric ovens, which are able to disable the processor unit. A wall split system, the indoor unit of which is supposed to be located in the kitchen, can not be installed in the apartment, since the inflow of air into this room should be provided by internal ventilation.

Wiring at connection

If you even choose the air conditioner with the lowest power at 1.5 kW, then it will be necessary for it to lay a separate wire with a cross section of 1.5 mm ² . The indoor unit of the multi-split system can be connected by means of a circuit breaker. If wiring to the shield is carried out, then the yellow wire with the green stripe must be connected to zero. The phase and zero must be defined by the indicator. If you decide to make the wiring from non-standard color wires, then zero and phase should be marked at both ends.

Conclusion

How to determine the power of the indoor unit of the split system, you learned by reading the article. However, it is important to accurately calculate the area of the room, because every square meter will affect the performance of the system. If this recommendation is neglected, then you may find that the air conditioner will be picked up incorrectly, also you risk overpaying for too high capacity or getting equipment that will not cope with the tasks assigned to it.
