When summer comes, many owners will install air conditioners at home. I'm afraid air conditioning is indispensable in summer. However, there are many doorways to install air conditioning. In order to save money, air conditioning brackets insist on avoiding stainless steel. Worker: You'll know when it falls! Some time ago, I asked my factory master to help me install the air conditioner. The master said that the ordinary angle steel bracket provided by the manufacturer is not durable, and suggested that I choose stainless steel bracket. Although expensive, the quality is safer. There are also alarmist suggestions, and don't let thousands of dollars of air conditioners be destroyed on this bracket, which will become the regret of high-altitude bombs. So is it really necessary to use stainless steel for installing the bracket of air conditioner?

First, the material of air conditioning bracket

The installation master said that there are many materials for air-conditioning brackets. Now there are three most commonly used ones, one is the most common angle steel bracket, the other is the galvanized sheet with antirust performance, and the other is the stainless steel air-conditioning bracket mentioned by the installation master.

2. What's the difference between these three air-conditioning brackets made of different materials? Which is better?

First of all, although we don't know how to install air conditioners, we should all know that outdoor air conditioners are mostly hung on the wall or directly placed on the balcony. When the outdoor air conditioner is hung on the wall, it should play the role of fixing the air conditioner bracket, so the stability of the material should be considered when selecting the air conditioner bracket. Stainless steel bracket has the characteristics of gas barrier, waterproof and rust prevention, so it can withstand wind and rain, and is more durable and safe.

In addition, in terms of service life, generally speaking, everything has its service life. The service life of ordinary angle steel bracket is 5 ~ 7 years, the service life of galvanized steel bracket is 7 ~ 10 years, and the service life of stainless steel air conditioning bracket is about 10 ~ 15 years, which shows that the service life of stainless steel bracket is better.

Third, let's talk about how to choose an air conditioning bracket!

In view of this situation, most houses are now designed with small platforms to place outdoor units, so a large number of users do not need brackets. Moreover, not all manufacturers produce original brackets, so users and merchants who generally need brackets will directly provide bracket purchase services, or the installer will provide brackets. Usually you only need about 25 yuan to buy it, but the quality can't be guaranteed.

Users are advised not to be careless when buying brackets, and buy cheap or expensive ones. After 5 years of use, if the screws are found to be loose or the bracket is rusted due to dripping water from the air conditioner, the air conditioner bracket must be replaced in time. Otherwise, when the external air conditioner falls and hits people, it will not be a matter of losing an air conditioner.

If the outdoor unit of air conditioner is hung on the wall, then choose stainless steel or galvanized steel bracket; If it is indoors or under the eaves, you don't have to bother to install the air conditioner with your own bracket, or just install an ordinary bracket.

The installation master said that we use better brackets not only to prolong the service life, but also to ensure the safety of pedestrians. If the quality of the bracket is not good and the external machine falls and hits people, our losses will be great. After listening to the words of the installation master, my colleagues suddenly realized that they finally bought a stainless steel bracket.

Four. Installation steps of air conditioner external unit bracket

1. Drill expansion bolt holes according to the position of the outdoor unit and the holes on the mounting frame, and the number and specifications of the holes must meet the requirements of the installation instructions;

2. Fix the outdoor unit mounting frame, and the number and specifications of expansion bolts must meet the requirements of the installation instructions;

3. Put the outdoor unit in place, insert the bolts, tighten the bolts after leveling, and the height difference of the outdoor unit per meter shall not exceed 5 mm;

4. Unscrew the interface cover on the outdoor valve and connect the refrigerant connecting pipe. When connecting, be sure to use two wrenches, fix the valve with adjustable wrench, and tighten the joint nut with torque wrench.

5. Connect the refrigerant connecting pipe to the pipe joint of the indoor unit. When connecting, be sure to use two wrenches, fix the connecting bolt with adjustable wrench, and tighten the connecting nut with torque wrench. If the condensate drain pipe is not long enough, connect it to the auxiliary nozzle in the machine;

6. Remove the control box cover of the outdoor unit, connect the cables to the terminals corresponding to the terminal board according to the number and color, and then install the control box cover;

7. Unscrew the indoor machine panel, the screws of the terminal board, connect the cables to the corresponding terminals according to the number and color of the terminal board, cover the junction box panel and tighten the screws; Some brands of air conditioners have been wired when they leave the factory, so this step is omitted at this time;

8. Plastic-seal the connecting pipe to make it close to the wall, wrap the joint with adhesive sponge, and wrap the connecting pipe and cable together with PVC packaging tape and pressure-sensitive adhesive tape;

9. Add half a glass of water to the condensate tank at the lower part of the indoor heat exchanger to test whether the drainage is smooth and cover the indoor machine panel;

10. Check the insulation resistance between the power cord and the ground wire of the air-conditioning power plug to ensure that the value is not less than 2M? ;

1 1, plug in the power supply and check the grounding resistance; If the user's power supply has no grounding wire, it needs reliable grounding.

I want to share with you the knowledge about whether it is necessary to use stainless steel in the installation of air conditioning brackets, hoping to help you. Nowadays, air conditioning brackets are almost used in most cases. There are many kinds of brackets. We can try to choose the most suitable one, but the stainless steel bracket is necessary.
