Whether it is an engineering project or a villa home decoration , if the installation of central air conditioning is not up to standard, it will cause a lot of trouble in the future. Therefore, when choosing central air conditioning, we must not only choose high-quality products, but more importantly, choose a good central air conditioning installation company. So if the central air conditioning installation is unqualified, what hidden dangers will exist, and how should we discover the hidden dangers?
　1. The indoor unit connecting pipe is leaking
　Inspection method: After the air conditioner is installed, run the air conditioner (refrigeration) immediately. If water droplets do not leak after running for a certain period of time, there will be almost no water leakage problem. Of course, the installer can also be asked to conduct a water leakage check to achieve the purpose of safe installation.
　2. Noise
　The wall of the indoor unit is not fixed during installation. If the indoor unit is not fixed, the noise will easily become louder. In this case, the installer can easily discover and correct the problem by using the trial machine.
　3. Electricity leakage
　Check method: See if the setter has relevant power check tools to check the power supply safely.
　4. Fluorine leakage
　Inspection method: Conduct refrigerant leakage inspection in front of testing machine . The inspection omissions mainly exist in the four interfaces connecting the internal and external piping of the air conditioner and the valve port of the closing valve.
　5. Wrong installation position
　Indoor units generally require the body to be 1.8-2.2 meters above the ground, and there should be no obstacles within 60 centimeters of the outlet of the indoor unit.
At the same time, there are also requirements for the outdoor unit. The outdoor unit should try to avoid places with heavy oil smoke, lots of wind and sand, direct sunlight, poor heat dissipation, or high-temperature heat sources. It should also avoid places where flammable gases are easy to leak, strong corrosive gases, and hazardous areas. There are hidden dangers such as the direct action of artificial strong electricity or magnetic field; the distance between the bottom of the installation frame and the ground should be greater than 2.5 meters. When it is directly dropped to the ground, a self-made isolation metal mesh should be covered to make it difficult for children to reach. If it is installed under a window sill, avoid Higher than the window sill; the mounting bracket must have an operating space that facilitates safe installation and maintenance.
