When air conditioning is used in our daily life, it will make people feel happy and enjoy a better living environment. However, when enjoying, we need to have a premise, that is, when installing, we must ensure air conditioning. Puncturing properly, so that in the process of use will be more comfortable and peace of mind, then, what are the methods of air conditioning drilling ? What are the precautions for air conditioning punching?
First, air conditioning drilling method
1. Drilling
Firstly, the scaffolding board and the protective rod are placed at the corresponding positions of the drill hole, then the cooling drill bit is placed to make the water hose more than one degree, and the drill bit with the outer diameter of 110 mm and the drilling depth of 300 mm or more is installed on the electric drill, and then You can start drilling holes, and you need to transfer water to the drill bit while drilling the hole to cool the bit.
2, install plastic casing
Use PVC pipe plastic glue to paste the plastic cover and the cover of the hole, and clean the dust remaining in the hole. Keep the hole dry during the cleaning process, and do not wash it with water. Then you can start installing the DN90 plastic sleeve. First fill the reverse side of the hole cover with silicone waterproof glue, and insert the DN90 plastic sleeve from the outside to the inside.
3, closed air conditioning hole
Injecting a polyurethane foam sealant into the glue gun, and then injecting the foam sealant into the gap between the plastic sleeve and the wall. After the foam sealant is completely solidified, the foam joint which is inflated out of the wall can be caulked. The shovel is removed and the mortar is finished. At this point, the air-conditioning hole has been roughly laid out. You only need to pass the pipe through the air-conditioned hole and install the air conditioner.
Second, air conditioning drilling considerations
1, the air conditioning eye is generally required to be horizontal, but the air conditioning eye is basically indoor high and some outdoor is lower, there is a slope, the empty obliquely downward opening point is to facilitate the condensate and rain after the rain and the wall The body is poured into the house.
2. Air-conditioning punching size: If the household air-conditioning duct passes through the beam above the doorway, there is no safety impact, because firstly the beam belongs to the secondary structure in the building and does not belong to the frame beam in the frame structure. There is no impact on security. Secondly, household air-conditioning pipes are generally less than 50mm, and such small holes will not affect the safety of the beams.
3, air conditioning hole angle problem, because according to the regular operation, the air conditioning hole should be inside high, low outside, there is a tilt angle, this is to prevent the outside water from pouring into the house. Whether or not air conditioning is installed, this angle must be there, because even if the gap is sealed even when air conditioning is installed, it is not completely tight. If there is water, it will flow into the house. This requires us to pay attention to the inspection when inspecting the house. If it is not qualified, the developer can be required to re-punch the hole and seal the original hole.
4. Many owners did not install air conditioners in the same year, so they sealed the air-conditioning holes with newspapers and other grasses, and some even did not handle them. This is very dangerous. If it is a low floor, small animals such as mice and bugs can easily climb into the house along the pipeline. When the fireworks are released in the New Year, Mars may also flow along the air-conditioning hole, causing a fire. Therefore, for the owner who is not in urgent need of air conditioning, the construction team can be required to use gypsum to seal the air-conditioning hole during the decoration. Be careful not to be too thick, and mark it well, and then open the plaster when the air conditioner is installed again in the coming year. .
5. Generally speaking, the developer will leave an air-conditioning hole in the appropriate position before handing over the house. Generally, it will be in the exit wall of the living room. The distance from the ground is generally about 35 cm, so if we want to smoothly pass the air-conditioning copper pipe. If you wear it outdoors, you must make a hole in the glass on the balcony, so it is not good to see, so the middle of the balcony window can not be punched.
6. There is a very important issue to be aware of, that is, do not hit the load-bearing wall, the property will not allow the operation of the load-bearing wall. If the load-bearing wall is moved, it is likely to cause certain safety hazards.
7, the punch hole needs to be lower than the inside, this can prevent the water from flowing to the house when it rains.
Third, air conditioning drilling location selection
The air-conditioning installation location should fully consider the spatial location and layout to make the airflow organization reasonable and smooth. The following positions should be avoided: the location where the flammable gas leaks or the environment with strong corrosive gas; the position where the artificial electric field and the magnetic field directly act; the position where noise and vibration are easily generated (for example, the air conditioner is installed on the protruding balcony) It will produce strong resonance and loud noise.
Usually placed under the window of the bedroom, through the window, wall, will greatly reduce noise. And it is easy to get under the window, and it is convenient to clean, repair, and set the air conditioner cover.) The location with bad natural conditions (like soot, sand and sand is very easy to damage the air conditioner, direct sunlight or high temperature heat source can make the air conditioner cool. Timely, cold air is not cold); children are easily accessible.
Air conditioners must be punched at the time of installation. The position and method of air-conditioning punching must also be very cautious, so that it can be installed better and more comfortable. The above is the air-conditioning punching method introduced by Xiaobian for everyone and the precautions for air-conditioning punching. If you want to know more about the decoration information, please continue to pay attention to the decoration home network.
