New problems brought about by building external insulation and air conditioning installation! 10

Most of the new high-rise buildings have external walls to keep the temperature insulated, about seven or eight centimeters, which is a necessary setting for modern energy-saving buildings.

DAO regurgitation. However, most of them have special answering stations for air conditioning, and some may not be very large, and they need to be enlarged by playing metal plates on the platform.

If you don't have enough space to install or must be installed on the exterior wall, the construction of expansion wires should be lengthened and filled with a full number, at least six lengthened expansion wires for an air conditioner, and high-rise buildings are mostly concrete structures, so be sure to install them on concrete walls and be easy to install. If your wall is too thick and the extended expansion wire is not enough to hang, you should break through the wall expansion wire and fix it firmly with a back plate.

Regarding the issue of outdoor unit brackets, the relevant departments do not have mandatory provisions that must be replaced within five years, and are included in the implementation stage, and there are special law enforcement agencies and departments to supervise. At present, it is still in the stage of advocacy of recommendations, and the implementation still depends on the will of individuals. For safety reasons, if you can feel that the bracket is already rusted without paint, and there are two long rust stains underneath, it is recommended to replace it.

The bigger the machine, the more important it is. This phenomenon mostly exists in old communities, and now emerging buildings will have special air-conditioning spaces, which greatly improves safety.

If your air conditioner has been used for more than five years, and it is still rusting badly on the street, it is better to replace it.

No problem, you can tell the installer that you can use a larger expansion wire, now it is a galvanized shelf. It won't rust.

An air conditioner will solve it for you, rest assured.

Yes, but to buy extended expansion bolts, the air conditioner comes with a general shorter, the specific length depends on the thickness of the external wall insulation, which can only be determined after the installer will be the bolt hole, the thickness of the external insulation in Beijing is generally about 6-7 cm.

In general, the following points are required:

1.Fixed mounting bracket: the mounting bracket is fixed with expansion bolts or long bolts, when the wall is thin or the strength is not enough, long bolts should be fixed, the bolts should be added with anti-loosening pads, otherwise it may cause loosening or falling, more than 6 fixed bolts, the diameter shall not be less than 10mm, after fixing, it can bear 4 times the weight of the person and the machine, and the bracket should be kept horizontal.

2.Fix the outdoor unit on the bracket with bolts with a diameter of 10mm, and the bolts should be worn from top to bottom, and add an anti-loose pad to check whether the outdoor unit is level. If the outdoor unit is installed in a place higher than the indoor unit, it should be installed as shown in the following figure, and its height difference should be less than 5 meters.

3.Connect the power cable and signal cable: Remove the cover of the electrical box of the outdoor unit, and connect the wires according to the pairing number in the junction box of the indoor unit and the junction box of the outdoor unit.

Fix the outer hanger with extended expansion screws.

The exterior wall is insulated, and the air-conditioning anti-theft door is installed to have a certain impact. You can reserve a place to install the air conditioner, but pay attention to the waterproofing around the nail hole and deal with it.

Ordinary household air conditioner plug-in machine mostly uses M8*80 expansion screws of M8*100 or M10*100 maximum, the thickness of the exterior wall ash is 2cm, the inner layer of polymer mortar is 1cm, the thickness of the extruded board is 3cm, the outer layer of polymer mortar is 1cm, plus 7cm together, and the depth of fixing on the wall is only 3cm with 10cm expansion screws.

It definitely has an impact.

The wall insulation board has a certain thickness, and the expansion bolt installation and fixation on the surface of the insulation board is not firm, so it must be installed on the wall. There are two options: 1. Install the air conditioning bracket or other fixings first, and then fill the installation position with a thermal insulation board; 2. If the insulation board has been installed, when installing the metal shelf or playing the expansion bolts, remove the insulation board at the installation site, let the expansion bolts adhere to the wall, and then repair and fill the insulation board after completion.

That's nothing、Your door in the concrete wall has nothing to do with insulation。

No, you can't.

For buildings with insulation on the exterior walls, the DU property does not allow the outdoor unit of the air conditioner to be hung on the wall, and this version is considered in the design of the building.

right, outdoor opportunity to have a place to put.

Do not destroy the main body of the house insulation, the house is not only lived for one year or two years, the façade insulation of the house is a whole, if the insulation fault caused by punching holes will appear cold, moisture return and other phenomena, so it is not recommended to install an air conditioning outdoor unit on the wall with thermal insulation.

It is better not to destroy the insulation of the main body of the house. First of all, the house is your own life, not the installation of air conditioning to live, they will only casually say that it does not affect the safety and stability, but the house does not belong to only live for one year or two years, the façade insulation of the house is a whole, if the hole is caused by the insulation fault, there will be cold penetration, moisture relapse and other phenomena, so it is not recommended to "move rough" on the wall with thermal insulation

The wall installation machine with thermal insulation should be installed through the wall with extended screws, and the insulation should be done back after installation without steam leakage.

Yes, yes. But if it's still upstairs, there's no problem in a year or two. Time is old and the façade is not very guaranteed.

The exterior wall of the bai building is a room with an insulation layer, and the general property does not allow the outdoor unit of the air conditioner to be hung on the wall, and the building is furnished.

DAO timer.

Considering this problem, there should be a place for the outdoor unit.

It is better not to destroy the insulation of the main body of the house. First of all, the house is to live by themselves, not to install air conditioning, they will only casually say that it does not affect the safety and stability, but the house is not only lived for one year or two years, the façade insulation of the house is a whole, if the insulation fault caused by punching, there will be cold penetration, moisture relapse and other phenomena, so it is not recommended to install an air conditioning outdoor unit on the wall with thermal insulation.

Yes, but you should explain it to the air conditioner installer in advance.

With extra-long expansion bolts, do not destroy the insulation layer.

**Air conditioning is a system engineering, in order to ensure the quality of installation and avoid rework, when installing, it should be designed and then constructed, and constructed according to the drawings.

1) Design. The design is to determine the installation position on the spot according to the prepared installation drawing. The indoor part of the household air conditioner is completely concealed engineering, using the concealed installation method, the indoor unit, air duct and wire, generally installed in the kitchen, bathroom, hallway, aisle ceiling, the required thickness of about 250mm. The tuyere is generally embedded in the wall above the bedroom door and the façade or top of the ceiling in the living room.

2) Construction. The whole process of construction can be divided into four steps to complete: the first step, on-site survey and lofting, which should be carried out by professional installers and the owner together; The second step is to drill holes through the wall, the outer wall needs to be drilled with air conditioning pipe holes and new air pipe holes, and the inner wall needs to be chiseled out of the air duct square hole; The third step is to hoist the internal and external machines in place; The fourth step is to connect the internal and external machine pipelines, and carry out the test machine, and seal the ceiling after passing the test.

**Introduction to the installation method of air conditioner

1. For the mechanical equipment of the air conditioner, the air conditioning construction process needs to be inspected and accepted before installation to see whether it meets the relevant specifications, and the relevant records of inspection and acceptance should be made.

2. Installation location of the indoor unit of the air conditioner: The poor installation position of the indoor unit will not only affect the actual use effect, but also cause a lot of physical discomfort. **The installation position of the indoor unit of the air conditioner needs to be coordinated with the interior decoration layout, usually hidden in the ceiling, or it can be hidden above the high counter.

3. Install ** air conditioning water supply and return pipes, condensate pipes, signal lines, etc., and maintain a slope of at least 1 100 for the condensate pipes laid, so as not to affect the decoration effect and ensure its normal discharge. When the refrigerant tube is installed, the cutting surface should be filed, the inner and outer burrs should be removed, the socket should be tight, and the outer surface of the refrigerant tube should be clean during welding. Nitrogen must be flushed into the copper pipe during welding, and soot blowing should be carried out in the pipe with high-pressure nitrogen gas after welding is completed to maintain the cleanliness of the copper pipe.

4. The air outlet of the air conditioner must be within 50 cm without obstruction, and the shock-absorbing pad should be installed in the floor type to ensure the normal operation of the outdoor unit. After the installation of the external unit, the refrigerant tube should be vacuumed to ensure that the refrigerant tube is dry, otherwise the moisture contained in the air in the tube will mix with the refrigerant to produce ice crystals, causing damage to the equipment.

5. After connecting the internal and external units of the air conditioner, a leakage check should be carried out to confirm that there is no leakage problem in the internal and external units and piping systems. Be sure to vacuum-drive to make sure the system is dry. If there is moisture in the system, it is easy to freeze the system and the electrical insulation will be damaged.

Finally, it is necessary to test run it to confirm whether the return air temperature, supply air temperature, operating current, voltage and other data of the air conditioner are normal.

The above is to introduce to you the installation method of the air conditioner, the installation method of the air conditioner may be a little cumbersome, because, the air conditioner and the hanging air conditioner are not the same, which one is very convenient to install, but, the air conditioner is not, before the installation to, we must choose a good installation location, but also to choose a position that is easy to clean later, we must carefully look at the steps introduced, well, the introduction is here, thank you.

1 Preparation.

Survey survey at the place of reinstallation. The installation location of the outdoor unit shall meet the following requirements.

1) The ground or wall should be able to withstand the weight of the body and vibrate.

2) The installation part should be easy to operate, adjust and maintain.

3) The noise, cold (hot) air and condensate that occur during the operation of the external machine cannot affect the work, study and life of others.

4) There should be no flammable gas leakage and ** around the external unit.

5) The outer unit should be installed in the back place as much as possible.

The installation location of the indoor unit should meet the following requirements:

1) Avoid direct sunlight on the unit and keep away from heat sources.

2) The air inlet and outlet of the internal machine should not be obstructed.

Measure the distance between the inner and outer machines. The distance between the inner and outer machines should be less than 5 meters, and new connecting copper pipes should be prepared if they are more than 5 meters.

Measure the difference between the inner and outer units. The distance between the inner and outer units should be less than 3 meters, otherwise it will reduce the refrigeration capacity of the air conditioner, increase the load of the compressor, and cause overload protection.

2 Installation. According to the above principles, after determining the position of the inner and outer machine, immediately install the internal machine hanging plate, and after the external machine and the internal machine hanging plate are installed firmly, then straighten the connecting pipe to see if the pipeline is bent and deflated; Next, check whether there are cracks in the flare at both ends, and if there are cracks, they should be re-flagged, otherwise fluorine will leak. Finally, check whether the control line is short-circuited or broken, and after confirming that the pipeline, control line, and outlet pipe are in good condition, tie them together and seal the connecting nozzle. When crossing the wall, two people should cooperate inside and outside the wall to slowly penetrate out to avoid strain; Connect the pipeline with the internal and external units, and connect the control line.

Next, remove the air from the ducts and the internal unit. Here's how;

1) Tighten the connected external coupling (fine) and loosen the stem of the shut-off valve with a special wrench about 1 turn.

2) Hear the squeak of the (coarse) joint of the external unit, and tighten the (coarse) joint with a sheet metal hand for about 30 seconds.

3) Loosen the stem of the valve on the (thick) pipe.

4) Completely loosen the stem of the shut-off valve on the (thin) pipe. The space-time witherer empties out.

Finally, use detergent for leak detection, carefully observe whether there are bubbles coming out of each joint, and after verifying that the system is indeed leaking, tighten the valve safety cap, and then start the test operation.

3 Run the debugging.

After the installation of the air conditioner, it should be supplemented with an independent air conditioner to use the power line, and the power cord of the household split air wither generally has 1 5 2 (mm) 2 three strands of copper core wire. The socket is 220V, 15A specification.

Check the voltage before powering on, and then use the remote control to start the operation. After the outdoor unit works, check whether the operating current is consistent with the nameplate marking, if it is less than the current marked on the nameplate, it can be regarded as a small amount of freon, and you are not in a hurry to add fluoride, you can continue to observe the condensation or frost at the pipe joint.

There is no air-conditioning space outside high-rise residential buildings, and the external tassel of the air-conditioning allows the machine to be installed on the balcony. Because the exterior walls of high-rise residential buildings are insulated, some of the exterior walls of the old-fashioned sample plots are hollow bricks. Even if the exterior wall is destroyed, it is difficult to ensure that the installation is secure!

In addition, once the exterior wall is damaged, the rainwater will enter the insulation layer and will seep into the interior.

When installing the outdoor unit of the Chun Zunian air conditioner on the balcony, it is best to install a door between the outdoor unit of the air conditioner and the living room to separate the balcony, the outdoor unit of the air conditioner and the living room, so that it will not affect the living environment in the living room, and it is convenient for the installation and maintenance of the air conditioner.

It should be noted that the relevant provisions in the national standard "Residential Design Code GB50096-2011" do not allow arbitrary changes in the location of the outdoor unit of the air conditioner. That is to say, it is not allowed to choose to install the outdoor unit of the air conditioner on the wall without the reserved outdoor unit of the air conditioner. It is advisable to understand the relevant regulations of the property before making a decision.

The main consideration is the issue of fire protection. The foam board used for external thermal insulation mainly includes: polystyrene board, squeezed shed silver-plastic board, phenolic board, polyurethane board and other cherry chain songs, the common point of these materials is that they are all organic insulation materials, and the combustion performance can not reach Class A, therefore, they are not allowed to enter the room for indoor thermal insulation.
