When to install an air conditioner during repairs: the optimal period for installing the climate unit

Connecting blocks

To connect the blocks, it is necessary to observe the correct connection of the cable colors. This shouldn't be a big problem.

Drainage

Drainage is carried out to the street or to the sewer. On the indoor unit of the split system there is a tube with a plastic tip, where the corrugated pipe is put on and crimped with a clamp. It is advisable to bring it at a distance of 1 meter from the wall

At the bottom of the outdoor unit, corrugated pipe is rarely used and everything is left as it is. The water just drips onto the ground.

Freon circulation system

Connecting copper pipes requires responsibility and good preparation.Before that, it is better to carefully read the instructions and study the connection points. Copper tubes should not be strongly bent and pass evenly with the rest of the communication.

The indoor unit has two ports for connecting two handsets. First you need to twist the nuts. If something hisses during this, it’s not scary, it’s nitrogen that comes out, which was previously pumped into the block.

After cutting the pipe, the ends are carefully checked for burrs and other roughness. For 5-7 cm, the pipe should be perfectly flat. Rolling is carried out according to the size of the port fitting

It is very important that the tube fits snugly on the fitting - this will prevent excessive loss of freon and ensure normal sealing

If everything fits well, the tube is connected to the port by screwing on the nut. There is no need to use gaskets or other devices. Such operations are done with all ends of two copper tubes.

Stage number 5. Garbage collection

Installing an air conditioner at some stages can cause pollution, especially if the walls are already finished. In this case, you need to prepare in advance and remove all fragile and valuable things if the installation is carried out after the repair and arrangement of the room. It is worth noting that real professionals always clean up after work, and they should come not only with tools for installing a split system, vacuum cleaners and sweepers, but also with a metal detector so as not to accidentally stumble upon fittings or hidden communications.

Even if the air conditioner is installed with high quality, this does not protect it from failure if it is not properly maintained.Not only the internal, but also the external unit of the split system needs constant cleaning. And if you can clean the first one yourself, then with the second one everything is much more difficult: not everyone dares to stick out from the nth floor with a vacuum cleaner and clean it. In this case, it is better to use the services of professionals or immediately conclude a service contract.

Winter starter for split system

On sale there are models of air conditioners designed to operate at low temperatures (in winter). As a rule, these are more expensive units than conventional split systems, and they already have a winter start system built into them. But for owners of conventional units, there is also the opportunity to improve their split system so that it can work at low temperatures. To do this, you need to install a winter start device, consisting of the following elements:

• heating block for compressor crankcase;
• heating block for drainage tube;
• condensing pressure control unit.

All installation work must be carried out by qualified specialists in order to avoid failures in the further operation of the system or the failure of expensive equipment.

Summing up, you can see that there are more pluses in installing an air conditioner in winter. In particular, this applies to residents of the southern regions of the country, where winter temperatures fluctuate around 0°C.

Technical requirements for the installation of blocks

There are a number of rules for choosing a place for installing air conditioner units, but the nuances are not always indicated in the instructions and technical documentation of the equipment, although they are very important during operation. Existing calculations for air conditioning systems require the obligatory observance of a number of parameters during installation

So, for the indoor unit, the following parameters must be observed:

• the distance from the top cover of the indoor unit of the air conditioner to the ceiling, to ensure normal air intake, must be at least 15 cm;
• the distance to the corner wall, to which the air conditioner unit is adjacent, is at least 30 cm;
• the distance to a possible obstacle to the movement of air blown into the room is at least 1.5 meters.

Failure to comply with these technical parameters may lead to a malfunction of the air conditioner and an increase in power consumption.

Also, the lack of air masses entering for cooling can lead to unstable operation and breakdown of the indoor unit of the air conditioner.

Installing air conditioners in apartment buildings on your own is actually not allowed by law. The existing norms of federal laws, civil and housing codes oblige to coordinate the moment of installation of air conditioners with the residents of the house, with the management company, with the executive authorities

As for the household rules for installing the indoor unit of the air conditioner, when choosing a place where the flow of cold air will be directed, it is necessary to exclude the possibility of a person permanently being there.

Cold air should not enter the resting place (sofa, bed) and work place (computer or desk). Otherwise, permanent illnesses cannot be avoided due to blowing with cold air.

To install an outdoor unit, the following parameters must be met:

• the distance from the rear wall of the outdoor unit to the wall of the building is at least 10 cm, otherwise the “capture” of external air will be difficult;
• keep a sufficient distance from the ground (when installing air conditioners on the first floors or in private houses) to prevent snow, dirt, water from entering the unit;
• install at a distance of at least 1 meter from gas pipes;
• provide at least 1 meter of free space for blowing air with a fan.

The outdoor unit of the air conditioner must be installed on the outer wall of the building adjacent to your apartment. You should also exclude the location of the block on the wall of a neighboring apartment. If necessary, provide the outdoor unit with a special visor - this is necessary to prevent icicles from falling on the air conditioner unit in winter.

When locating the outdoor unit, it is important to take into account the possibility of free access to it for maintenance. The installation of an outdoor air conditioner unit on the first floors must be carried out in compliance with the conditions for the unhindered passage of pedestrians near the walls of the house

It is also worth protecting with a special grate to prevent vandals from affecting the unit.

The installation of an outdoor air conditioner unit on the first floors must be carried out in compliance with the conditions for the unhindered passage of pedestrians near the walls of the house. It is also worth protecting with a special grate to prevent vandals from affecting the unit.

It is worth noting that at the dawn of the mass installation of air conditioners in apartment buildings, it was believed that the outdoor unit must be installed lower than the indoor unit. This myth was based on the fact that this is how the compressor of the outdoor unit will be constantly lubricated with oil (otherwise oil supposedly collects in the indoor unit).

From the point of view of the location of the external and internal blocks, the determining parameter is the distance between them. The established framework is from 1 to 6 meters, but the manufacturer may indicate specific parameters that should be strictly observed.

If the maximum allowable distance (more than 6 meters) is exceeded, freon will have to be additionally pumped into the system, and if located less than a meter, it is necessary to form a ring from the tube to provide the necessary footage.

We discussed in more detail the issue of choosing the right place for installing an air conditioner in our other article.

Recommendations for the use of technology

After choosing and installing a split system, it is advisable to determine the parameters of competent operation:

1. Do not open windows when the device is turned on.
2. Do not use critically low temperatures.
3. Do not turn on the heating function when the outside temperature is below zero.

Ventilation is a necessary action when using a split system, since it device by virtue of its structures cannot do this (except for models with air intake).

However, the room should be ventilated only after the units are turned off, so as not to load the unit.

During the day, it is recommended to lower the temperature gradually, decreasing by 2-3 degrees per hour, smoothing out the contrast differences. And at night, a higher temperature is considered comfortable for sleep, it will be correct to increase it by a couple of degrees manually or by the “sleep mode” function

In the summer months, it is not recommended to set the minimum values ​​​​of 16-17 degrees, even with strong heat, the optimal difference with external values ​​\u200b\u200bis 5-10 degrees.

In order for the compressor not to wear out faster than the term and the system components are not subjected to increased load, operating at maximum power, comfortable temperature values ​​should be set from +20 to +27 degrees.

The longer the device works, the better it cools the air. If the indoor unit of the system is exposed to direct sunlight, it is recommended to shade the unit. For this purpose, you can cover the window with curtains or blinds.

Another situation is how to properly use an air conditioner for heating in the cold winter months, when the physical characteristics of the freon-oil mixture change at sub-zero temperatures?

After all, the inclusion of equipment in frost can entail, if not an instant stop and a drop in efficiency, then freezing of the drainage tube and blocks, the risk of failure of the compressor and fan.

If there is a need to use the air conditioner in frosty weather, you can purchase a special “winter kit”, the installation of which will protect the equipment from breakdowns.

The winter kit for split systems allows you to use the equipment even in severe frosts. The only downside is the rather high cost.

However, split systems are designed for use at positive temperatures outside the window, therefore, it would be wise to use them to heat the room only in the fall before turning on the heating.

Installer options

Manufacturers of climate technology claim that 90% of breakdowns in the first year of operation occur due to poor-quality installation of devices.

Mounting and connection of blocks can be done using:

• Service from the selling company. A trading company with a long history and a good reputation will provide the service, most likely at the highest price.But on the other hand, you will have someone to ask if the unit breaks down during the warranty period.
• Specialized services of assembly organizations. They are provided by both independent companies and divisions of construction companies. You can invite specialists for consultations and perform the most complex operations.
• Do-it-yourself installation of the air conditioning system. The most economical way, suitable for tech-savvy experienced craftsmen. If you are confident in your abilities - why not. Dare!

In the process of installing the outdoor unit and the internal part of the device, there are no secondary actions. Every very slight negligent deviation from the technical requirements leads to big problems in the operation of the air conditioner.

Minor flaws in the installation of the external unit of the split system threaten to increase noise due to vibration. The wrong angle of the drain hose will direct the collected condensate not to the street, but back into the room

Carefully monitor the high-quality rolling, do not bend the pipes. The correct operation of the air conditioner depends on them. Marriage in working with pipes is fraught with freon leakage, disruption of the cooling process, and breakdown of expensive equipment.

When to install an air conditioner during repairs: the optimal period for installing the climate unit

The timing and sequence of repairs should be planned as carefully as possible.

After all, is it true that without a clear calculation, it will turn into an endless natural disaster? It is important to determine such a time period when it is reasonable and profitable to install an air conditioner when repairing an apartment.

Determination of not only the optimal time of work, but also the season for the purchase and installation of equipment will significantly save your budget.We will make this task as easy as possible for you by equipping you with the necessary modern knowledge.

After painstaking research work, we have identified the most important points of installing an air conditioner. They will help you to include the order of purchase, installation and activation of the climate control device into the individual apartment renovation schedule.

Comfortable stay in an air-conditioned room

The temperature is the most important factor, but not the only one, which is affected by the air conditioner running in the room.

In addition to maintaining the temperature at a given value, the air conditioner dries the air. This leads to the fact that the mucous membrane of the nose and throat can dry out. For some people, this causes discomfort in the form of a runny nose and sore throat.

The optimum humidity is considered to be 40-60%. It is measured with a hygrometer. Modern devices, in addition to humidity, also report other important components of the microclimate.

This can be avoided by installing a humidifier in the room. It is also recommended to drink more water, this will protect your mucous membranes from drying out.

Stage number 1. Outdoor unit installation

As you know, an air conditioner, or split system, consists of two blocks - indoor and outdoor. It happens that several internal ones are connected to one external one, then this is already a multi-split system, which is used in large houses, office buildings, institutions where they do not want to spoil the facade with many separate blocks. The outer and inner parts are interconnected by wires and a pair of copper pipes through which freon flows, and a thin tube, drainage, which serves to remove condensed moisture, also leaves the external unit of the split system.In theory, the drainage should be connected to a sewer or to a special drain pipe, but most often you can see a picture when liquid drips on people walking down the street.

The principle of operation of the air conditioner can be described as follows. When the room needs to be cooled, freon enters the internal unit through one of the copper tubes, where it is blown by a fan, and as a result, cool air enters the room. At the same time, the indoor unit works almost silently, and some manufacturers have already managed to achieve 26 dB. The external unit makes a little more noise, but for this it is taken out of the room.

Installation of the outdoor unit begins with drilling holes in the wall for brackets, where the device itself will then be attached. The brackets must be very strong and able to support a weight much greater than the weight of the outdoor unit. The problem is that it will be difficult to install these brackets without special equipment, if the apartment is not on the ground floor. So, you will have to use the services of either a special car with a retractable ladder, or, if it is the sixth floor and above, the services of a climber.

Attach the air conditioner to the brackets so firmly that it does not fall on people passing below. After all this, it is already possible to connect communications to the external unit

It is important that the wall is strong enough to support the weight of the outdoor unit, and smooth so that it does not deform over time.

For those who live on the ground floor, it is better to protect the outdoor unit with a grill, since there are many cases of their theft.For residents of the last floors or private houses, it can be advised to install an outdoor unit on the roof, but it should be borne in mind that the distance between the two parts of the split system cannot be more than 3-20 meters (depending on the features of the chosen model). At whatever height the air conditioner is installed, it is better to make a small visor above it: in this case, snow and icicles that fall from the roof in spring will not be able to damage or knock down this part of the split system.

When to install the air conditioner?

When to install the air conditioner?

Theory and practice, statistical research.

If you asked yourself this question today and do not know how to answer it, then I will help you and I will answer it quite clearly and convincingly and justify it from a somewhat unusual point of view.

This text was created and posted in March 2013, but the information is still relevant and applicable to today. Therefore, we do not edit the article and do not take a new reference period. Let everything be as it is.

I hope this application of theory to practice will surprise you. How to combine seemingly incompatible things?

The temperature outside is still below zero

When the temperature on the thermometer shows such a value, then the air conditioner should already be in the apartment.

The temperature outside is about 33 degrees Celsius.

The thermometer rises higher and higher.

Have you installed the air conditioner yet?

It's already over 40 degrees outside

A small preface.

It is necessary for the further development of our question. You are on the site for air conditioners, their installation, VRV systems, ventilation and everything connected with it. But, as you noticed, there are other topics here that are interesting to me and unite both work and leisure: what does the installer do in the winter, ... seo, WordPress ...

Having created a site on a whim, as it should be in our opinion: with our own written articles, without using the services of copywriters, we stopped for a while in its development.

Important

After a little rethinking and seeing how it differs from other similar sites and blogs created on the Internet, we downloaded several books on SEO optimization to our tablet, read the blogs of people who write on this topic, but this is not about that now.

After reading a lot of information on this topic, I realized that something was wrong with my site. It turns out that I made a gross mistake in creating it, it was not a website, but some kind of bulletin board from the 70s, transferred to the Internet, into the 21st century. And here I found the answer to my question, which I put at the beginning of this article:

When should you install air conditioning in your home?

– when can I buy it at the cheapest prices in the store?

– when can one of the most expensive brands of Daikin air conditioners be purchased at significant discounts?

Now read carefully.

When creating a site, you can and should use keywords. And use them in a variety of forms, cases, phrases. For this, the Yandex search engine has -

Now, by typing on this page the phrase we need “installing an air conditioner”, and selecting the section there - by weeks, we see a clear schedule.

Schedule of installation of air conditioners for the period March-February 2012-2013

If today is March 2013, then here we see a curve on the chart that stretches from the date March 2012 to February 2013.

Quite right, you can see on the graph how often visitors to the pages typed the desired combination on the Internet. The chart shows the ups and downs very clearly.

The number of requests for this phrase in figures by month

And this is not only the amplitude of the frequency of typing, but also the Market, which shows well what and when is in demand and supply.

Let's not take one word yet, the last one, and see what the graph will turn out to be.

The word is air conditioners.

All.

You can see for yourself how these two amplitudes coincide. This word is typed for the Moscow region and the Moscow region.

Advice

That's when you need to buy air conditioners and install them, in December - January. When the curve is at its lowest point.

I hope that the slightly lengthy and, perhaps, boring text did not tire you. With a little imagination and different ideas, you can use a set of words in this search engine: - directly for your business, - making your purchases at the lowest price, - many other things ;)) you just have to be creative for this.

This is the kind of information I acquired by starting to read books about website optimization and directly connecting the new knowledge with my work installing air conditioners.

Now I know this market too. And you also now know more.

And this is a graph covering a much larger region with the word “air conditioners”.

Calculation of the power of the device

Saving on purchases by purchasing a cheaper model of air conditioner due to low cooling capacity is short-sighted. A weak device will not cope with the cooling of a large sunny room.

And you expect such "surprises" as:

• discrepancy between the set temperature and the actual one;
• quick breakdown of the air conditioner due to overheating;
• unnecessary expenses for maintenance, repairs.

You can determine the cooling capacity of the air conditioner required for a particular room from a simple calculation - divide the area of ​​\u200b\u200bthe room by 10. This is with a standard ceiling height of 2.5-3 m. If the ceilings are higher, increase the power in proportion to the height.

For example, for an area of ​​15 m 2 and a height of 3.5 m, a 1.8 kW device will suffice. The attic will require more power, increase by another 2-3% in proportion to the number of people constantly in the room. For the sunny side, add another 10 percent. As a result, the maximum cooling power of a home air conditioner should not exceed 4 kW.

Refinement of the split system for winter operation

The winter kit for the air conditioner is equipped with devices that prevent the refrigerant from being excessively supercooled, provide heating for the drainage line and keep the oil in a liquefied state.

The principle of its work is as follows:

• the crankcase heater heats the oil in the compressor, which bears the main load during start-up, especially in winter;
  a device for heating the drainage system both from the inside and outside, allows condensate to freely exit through the drainage tube, preventing the formation of an ice plug;
• the temperature sensor detects their decrease in time on the street and slows down the fan on the external unit of the device, so that frost does not form in it, and problems with reduced performance of the split system are solved along the way.

The winter kit is installed once and then performs its functions automatically - it works when it gets cold. Now the information about the temperature up to which the air conditioner can be turned on, written in the device manual, can be neglected, because the winter set significantly expands its capabilities - on average to -15 ° C, and in the absence of strong wind up to -20 ° C. The temperature range can be further increased, although this is usually not an economically justified measure.

The operation of an air conditioner improved with a winter set is permissible at a lower temperature threshold, however, this is true only for the cooling mode! When heated, everything will remain unchanged, moreover, there will be a risk of water hammer.

In addition, a low-temperature air conditioning kit can sometimes cost more than the unit itself. Cheaper and easier to install it immediately when installing a split system. It is worth remembering that the warranty for equipment will only apply if it was installed by service center specialists, and not by the owner on his own.

How long does it take to install an air conditioner?

Installing an air conditioner is a responsible, rather complicated and time-consuming process, so it will not be possible to carry out the installation as quickly as possible, no matter how much the customer would like it.If the air conditioner was purchased in winter, it is better to wait until spring with installation. The fact is that it is problematic to check the performance of the installed equipment in frosty weather. The optimal time of year for installation is from spring to the onset of the first autumn-winter frosts. How long does it take to install an air conditioner? To give a specific answer, you should consider what activities are carried out during the installation of such equipment.

Should I do the installation myself?

The principle of installing an air conditioner is generally simple, but the details are very important. So, it is necessary that both blocks are installed evenly - without distortions. Otherwise, condensation may accumulate and, as a result, an early breakdown of the device.

In addition, some companies provide a wider warranty if the installation is done by their qualified specialist, which is quite understandable: this dismisses all doubts about improper installation as a probable cause of unit failure. However, for any air conditioner in the instructions there is a detailed description of how exactly this device should be installed. Therefore, if there is an irresistible desire to do the work on your own, this is quite real.

True, it may be difficult to find a tool in order to install the brackets and drill a hole for the freon tube. And on the floors above the first one, it is not so easy to install an outdoor unit: insurance is required. Specialists will have no problems with this - all the equipment is included in the kit, they know how to use it, they do it quickly and efficiently.

A properly installed air conditioner does not emit extraneous sounds.It requires only preventive cleaning once or twice a year - in spring or spring and autumn, depending on the intensity of use, as well as refilling with freon once every two years.

For many, air conditioning at home has become simply indispensable. It creates a comfortable microclimate in the room when it is hot outside. But this is only possible if it is installed correctly.

Preservation of equipment for the winter

If the climatic equipment is not planned to be used during the cold season, then it is necessary to prepare the air conditioner for the winter, i.e. its conservation.

On a fine day, when the thermometer does not fall below +16°C, you need to turn on the equipment in ventilation mode for 1.5-3 hours so that all the moisture in the heat exchanger of the indoor module evaporates. If it is colder outside, it is recommended to use the heating mode instead of ventilation.

In addition, it is necessary to clean the filters of the split system from dust and dirt. You need to get them by opening the front panel of the device, rinse with running water and soap, dry and install back.

Disconnect the split system from the mains and remove it from the remote control to avoid battery oxidation.

It is not recommended to cover the outdoor unit of the air conditioner with moisture-resistant materials, because due to the accumulation of condensate, as well as the inaccessibility of solar heat, mold will soon form on the outdoor unit.
