Said air-conditioning "three-point quality seven-point installation", showing that air-conditioning installation plays a vital role in the quality of air conditioning. In the air-conditioning shopping season, due to unqualified air-conditioning installation caused by air-conditioning leaks, air-conditioning is not cooling, and excessive air-conditioning noise and other phenomena are common, and how do we actually put an end to these hidden dangers?

Today, the author will give you a brief introduction to the installation hidden dangers when air conditioning installation fails, including detection methods. Interested friends may wish to learn together.

Hidden I: indoor unit leaks

Inspection method: After the air conditioner is installed, immediately run the air conditioner (refrigeration). If there is no water leakage for a certain period of time after running, there will be no water leakage problem. Of course, installers can also be required to perform leak testing to achieve safe installation.

Hidden Trouble II: Leakage of fluorine

Inspection method: The refrigerant leakage inspection should be performed before the test machine. The leak detection is mainly for the four interfaces of the air-conditioning inside and outside the air-connected pipes and the shut-off valve ports.

Hidden trouble three: leakage

Inspection method: See if the installer has the relevant power detection tool and perform safety test on the power supply.

Hidden trouble four: installation location

The indoor unit generally requires the fuselage to be 1.8-2.2 meters away from the ground. There must be no obstructions within 60 cm of the outlet of the internal unit.

At the same time, there are requirements for the outdoor unit. The outdoor unit should try to avoid places with heavy smoke, lots of wind and sand, direct sunlight, poor heat dissipation or high-temperature heat sources, but also to avoid the easy leakage of flammable gases, strong corrosive gases, and labor Strong electricity or magnetic field direct action and other hidden dangers; the distance from the bottom of the mounting frame should be greater than 2.5 meters away from the ground, should be covered directly on the isolation metal mesh cover, so that children are not easy to touch, if installed under the windowsill, to avoid high On the sill; mounting brackets have an operating space for safe installation and maintenance.

Hidden danger five: noise

In the installation, the internal wallboard is not nailed and the internal machine is not fixed. It is easy to cause excessive noise. In this case, the installer can easily find and correct the problem through the test machine.

At the same time, the dust in the condenser of the filter evaporator is blocked and the air supply is not smooth, which may cause the air supply noise to increase. The lack of fluorine in the system can cause abnormal noise in the compressor. Therefore, after a long period of idle air conditioning, air conditioners should be thoroughly cleaned before the air conditioners are used, and the indoor environment is also healthy.
