One split system 2 rooms. Installation of air conditioners in two stages. The nuances of laying the route for installation teams

For two internal blocks, i.e. You can connect two split systems to the external unit and place them in two separate rooms.

Ideal option in the absence of free space on the facade of the building.

Models of multi split systems for two rooms

IN lately The use of such an air conditioning scheme is becoming increasingly popular. This is explained by the fact that often in newly built multi-story buildings residential buildings allocate a special place for the external unit. This area is protected by a decorative basket. But what if you need to cool two rooms, but there is only one place for an outdoor unit?

There is no fundamental difference from a conventional air conditioner. By the way, many people think that multi-split should cost less. Unfortunately, this is not true: the cost of the equipment itself and its installation will be approximately the same amount. Outdoor unit is initially more reliable, and the total length of the routes, as a rule, is slightly longer than when installing two independent air conditioners, so installation will cost a little more, even despite the need to display only one air conditioner on the facade.

The only “inconvenience” is that the external unit is capable of providing internal operation either only in cooling mode, or all in heating mode. On the other hand, it is difficult to imagine a situation where it is necessary to cool the air in one room and heat it in another. It is worth noting that the internal units of such an air conditioner are in all other respects absolutely independent and operate independently.

Japanese brands are rightfully considered the best and most reliable air conditioners. Such as Daikin, Mitsubishi Electric, Mitsubishi Heavy, Toshiba. Based on our experience and statistics of equipment failures and service cases, we strongly advise you to choose a split system from Japanese manufacturers when choosing an air conditioner for 2 rooms. This is reliability, this is build quality, this is functionality.

Works on many models special offer: standard installation as a gift! Check with the managers: you will be pleasantly surprised by the final price including installation!

Therefore, do not be surprised when you see the cost of “0.0 rubles” in the “Installation” column. This is true.

Main differences between the models different manufacturers- this is the cooling power, the dimensions of the external units and the functionality of the internal units of air conditioners. And the price, of course. The most reliable brand - Daikin and Mitsubishi Electric will cost 20-30% more than their analogues. But this is a 100% guarantee of durability and efficiency. Indoor units are selected for each model separately, taking into account the required cooling power and required functionality.

“Installation of an air conditioner in two stages” is the most common and popular method of installing an air conditioner in premises that are under renovation (or construction to build a house).

The method of installing an air conditioner in two stages is very popular, as it allows you to free up the room space from unnecessary wires on the wall, while maintaining the interior design desired by the owner.

Installation is done in two stages engineering communications from the air conditioner (freon route, electrical wiring) invisible in the interior due to their placement in a special recess in the wall, the so-called “groove”, and therefore this installation is also often called “ hidden installation air conditioner."

This, the most aesthetic option for placing the route and air conditioning units, is also the most labor-intensive, since it is divided into two different stages carried out at different stages of repair and at different times.

This installation is divided into two main stages:

The most important thing in installing an air conditioner in two stages is to ensure that the system remains sealed and to prevent damage to the routes hidden in the wall during repairs and finishing work in the room. Such cases are common when, after the first stage of work (laying routes into the wall), workers of a third-party organization carrying out renovation work damage the air conditioner routes and during the second stage of work (inter-unit connection of the air conditioner), a freon leak occurs, which entails the need to re-lay the routes (after finishing the walls!).

The site has a rule - issuing to the owner a plan diagram of hidden communications laid for the air conditioning system in order to minimize the possibility of damage to the route.

Distinctive features of installation on the site:

cleanliness of climate control work: when installing an air conditioner after repair, the company’s installers will protect the interior from possible contamination(all work is performed with an industrial vacuum cleaner) and will remove debris (air conditioner packaging, remnants of working material, etc.);
guarantee of safety of hidden communications: you will be provided with a plan diagram of hidden communications to ensure the safety of the routes and the tightness of the air conditioning system.

The cost of installing an air conditioner is in two stages.

The cost of installation in two stages depends on the model of the air conditioner, its power, the method of placing the air conditioner units in the room, the laying pattern and the length of the route.

You can call a specialist for an inspection and consultation on the location of the routes and placement of the indoor and outdoor air conditioner units by sending us a request on the website or by phone.

Installation service MERIT SERVICE: We install the air conditioner in two stages inexpensively. 22 installation teams, own spare parts warehouse, installation and service of domestic and industrial air conditioners.

When installing an air conditioner during renovation of a room, inter-unit pipes and cables, as well as a drainage pipeline, are usually laid in a groove. This installation is performed in two stages and allows you to hide all visible communications. The indoor unit is installed last.

IMPORTANT

When installing an air conditioner in two stages, the quality of installation materials is very important. Because our company gives guarantee for air conditioners and installation work; we are primarily interested in the quality of work, and accordingly we use only the most quality materials and components.

The copper pipe we use is of the highest quality and guarantees the absence of microcracks and creases at bends and in places of rolling. All materials used have certificates of conformity.

The procedure for installing the air conditioner is in two stages:

Decide on the location of indoor and outdoor units.
Draw and execute grooves. 1
Complete stage 1 installation work. Hang the street block. 2
Complete repairs and finishing work in room 3
Carry out the 2nd stage of installation work. Commissioning (incl. vacuum) 4

1 The cost of gating work is not included in the standard installation and is paid additionally. You can do them either yourself or with our installation service. See prices for gating work on the page . To draw grooves you can use .

2 At your request, the air conditioner can be purchased both at the first and at the second stage of the work. Its cost is paid accordingly at the time of purchase.

3 There is no time limit for completion of work at the site.

4 The period for completing the second stage of installation and commissioning work is, as a rule, 2-3 working days from the date of your application for installation of an indoor air conditioner unit. The cost of performing the second stage of work depends on the capacity of the equipment and the remoteness of the facility. For household air conditioners in Moscow and the region it is usually 2000 rubles.

Stationary climate systems are almost always installed in rooms. Such split systems consist of two blocks, internal and external. If the customer needs to install an air conditioner for two rooms (or more), then options for using multi split systems, which consists of one external and several (one for each room) internal blocks.

To substantively consider all the pros and cons, it is important to know the type of property. Depending on the type of object, you can install a regular multi-split system or a duct one.

IN apartment typical buildings and low ceilings, air conditioning for 2 rooms is installed only as a wall type. It looks the same as installing an air conditioner in one room, only outside there will be one common external unit of increased power.

Saving space on the building facade. This often helps maintain aesthetic properties.
If the internal units are well located, installation will be simplified and cheaper. The final price of an air conditioner for 2 rooms is reduced.

Impossibility of separate temperature control in rooms.
If the external unit fails, both internal units stop working.

In addition, it should be noted that installing a multi-split air conditioner for 2 rooms in most cases cannot be cheaper than installing separate split systems, due to additional equipment inside the external block, the complexity of installation and laying the same (often) amount of routes in the walls for communications.

Air conditioning for several rooms

IN country house, office building or apartment with HIGH ceilings can be installed channel system. Duct air conditioner for several rooms mounted behind a hanging/ suspended ceiling, which hides the air ducts and the indoor unit itself.

Household duct multi split system.

Ventilation- Possibility of introducing fresh air.
Opportunity in different rooms. To provide this capability, additional motorized valves and thermostats must be installed in each room.
Hidden indoor air conditioner unit.

Reducing the ceiling height by 15-20 cm for installing air conditioner ducts for several rooms. But if the installation of suspended/stretch ceilings was planned initially, then this is not significant.
Rise in price final check of the system and installation when adding a function separate temperature control.

Semi-industrial multi split systems VRV (Variable Refrigerant Volume). Climatic equipment of the whole cottage, office building, a public facility.

The advantages are added:

Installation of the external (central) unit anywhere(roof, basement, separate building).
Full separate temperature control in different rooms.
System control using a PC.
Distance between the external and internal blocks up to 100 meters, while in household systems 25 meters.
High accuracy set temperatures ±0.5 °C.
Verified energy savings.

The need for detailed study of the project.
Systematic checks and revisions of parts of multi split systems.

Installation of air conditioner during repair

85% of split systems are installed during the renovation stage!

Those. This is the rule, not the exception. After all, few people want to see boxes on the walls - the result of installing an air conditioner during a completed renovation. But at the finishing stage, freon routes can be hidden. Within the walls. Under the ceiling. Lay it on the floor.

And we do it well.

Installation of the air conditioner in two stages, at the time of repair in the room

You are on the website of a professional climate control company. If you need to install an air conditioner in two stages, entrust your facility to professionals. Below are some examples. Including short videos sketches.

Am I limited in time for repairs?

No! We have clients whose time difference between the first and second stages was three or even four years! Rest assured that we will come and finish what we started.

All more clients are thinking about installing an air conditioner at the stage of renovation of the premises. And this is correct: in this case it is possible to conduct communications (inter-block route) in the wall. The order of actions and operation of each stage is described below.

First stage work on installation of air conditioners

A specialist (surveyor) goes to the site. When installing an air conditioner in two stages, a specialist visit is required. This is explained by the fact that this installation implies significant variability in the placement of both the air conditioner itself (its internal and external units) and the route.

The first and second stages of work

Installation of multi-split during renovation

When installing an air conditioner at the time of general construction work, the drainage can be diverted into the sewer system so that it does not drip outside. The lowering of ceilings, the construction of partitions, electrical connections, etc. are taken into account. in general, the technical feasibility of installing an air conditioner according to the scheme requested by the customer.

The scope of work is agreed upon with the customer
The groove is being executed. In this case, the customer can carry out the deepening of the walls using his own team: after the measurement, a drawing and a communication diagram remain at the site
The external unit of the air conditioner is hung up and secured on power brackets (at the first stage of installation, you can basically do it WITHOUT equipment: install it when the team leaves again, at the final stage).
Drilling a hole in the wall
The communications route is stretched and connected to the external unit (connection - rolling). Drainage is discharged in accordance with the agreed scheme (either to the street or to the sewer).

This completes the first stage. We are waiting for your repair to be completed. At the same time, the customer is not limited in terms of time: the time interval between the first and second stages can be a week, or maybe a year. Prices in the contract are fixed and unchanged, unless there was an additional agreement related to changes in design solutions at the facility (replacement of equipment, change in the list of works agreed upon by the customer, etc.).

Is it possible to lay communications without equipment?

Easily! Household wall-mounted inverter air conditioners up to 35 m2 from almost all manufacturers are mounted on one type of route (1/4" - liquid pipe, 3/8" - gas pipe). The air conditioner simply arrives at the site upon completion of the work.

IMPORTANT: The freon circuit sticking out of the wall must under no circumstances be bent! Once you bend the copper tubes a couple of times, they will become unusable, i.e. will change their cross-section and may develop microcracks, which will inevitably lead to incorrect operation of the split system and the possible release of freon with oil... and this is when repairs have already been completed.

Second stage work on installation of air conditioners

The "dirty" work is completed. You have had fine finishing. Here is an example of completing work on objects:

Completion of work after completion of repairs

The second stage of work on installing a split system

The plate of the indoor unit is attached to the wall indoors.
The route connects to the indoor unit.
The split system route is evacuated: connected vacuum pump with the help of which atmospheric air that contains moisture is pumped out.
After the installers make sure that the connection is correct, the valves open and freon is released into the route.
The functionality of the unit is checked in all modes. The work is handed over to the customer.

Installation of air conditioner in one stage

This type of installation of split systems is one of the simplest and is usually completed within one day (an experienced team spends about 2-3 hours to install one air conditioner without additional work). When ordering installation in our organization, lifting with working elevators is free of charge; the cost of equipment delivery, depending on the type, is negotiated with the manager who manages the facility.

If the facade of the building is brick or concrete slab, then the team starts working independently and immediately. If the facade is “breathing” tiles (ventilated facade) or the height of the external block is more than 65-70 cm, then most likely you cannot do without a climber.

The order of work is approximately as follows:

The manager asks a number of questions (type of façade, right- or left-hand installation, width window openings etc.), which allow you to determine the nature of the work. In 80% of cases there is no need to take measurements
Before starting work, all necessary measurements are taken and the location of the blocks is agreed upon with the customer. Assessment of the possibility of signage of blocks taking into account the customer’s wishes
The brackets are fastened (installation of the stand - when performing floor mounting on a loggia or balcony) to the facade
The external unit of the air conditioner is hung and secured on the power brackets.
A hole is drilled in the wall. Subsequently, the hole is sealed and insulated. thermal insulation material, used for thermal insulation copper pipes
The communications route is extended and connected to the external unit (connection - rolling). Drainage goes outside
The plate of the indoor unit is attached to the wall indoors
The route connects to the indoor unit
The split system route is evacuated: a vacuum pump is connected, which pumps out atmospheric air that contains moisture. This allows you to: firstly, check the tightness of the rolling joints before starting the freon; secondly, get rid of moisture, which leads to oxidation of the compressor oil and incorrect operation of the external air conditioner unit
After the installers make sure that the connection is correct, the valves open and freon is released into the route. It is worth noting that with significant lengths of the inter-unit air conditioner route, refilling of freon is required, because in the external unit, as a rule, freon (factory injection) is enough for a route up to 7 meters long
The functionality of the unit is checked in all modes. The work is handed over to the customer. With this installation scheme, the main part of the inter-unit air conditioner route remains outside, running along the facade. A small part of the freon circuit connecting the external and internal units and located indoors is hidden in a decorative box. Standard installation includes up to 1 meter of box.
