Five hidden dangers caused by unqualified installation of central air conditioning

Release time:2019-12-19 Clicks:100

Abstract】:Central air conditioning engineering is very particular about installation. Improper installation of central air conditioning will not only affect the refrigeration effect, but also cause five hidden dangers. Hidden danger 1: the connecting pipe of indoor unit leaks water; inspection method: after the central air conditioner is installed, run the air conditioner (refrigeration) immediately. If there is no water drop leaking after a certain period of operation, the problem of water leakage will not appear basically. Of course, the installation personnel can also be required to conduct water leakage inspection to achieve the purpose of safe installation.

Central air conditioning engineering is very particular about installation. Improper installation of central air conditioning will not only affect the refrigeration effect, but also cause five hidden dangers.

Hidden danger I: leakage of connecting pipe of indoor unit

Inspection method: after the central air conditioner is installed, immediately operate the air conditioner (refrigeration). If there is no water drop leaking after a certain period of operation, there will be no water leakage. Of course, the installation personnel can also be required to conduct water leakage inspection to achieve the purpose of safe installation.

盈彩厅Hidden danger II: fluorine leakage

盈彩厅Inspection method: check the refrigerant leakage before test. Leak detection is mainly aimed at the four interfaces of the air conditioner internal and external machine connecting pipes and the valve ports of the stop valves.

Hidden danger 3: leakage

Inspection method: check whether the central air conditioning installation personnel have the relevant power supply inspection tools and carry out safety inspection on the power supply.

Hidden danger IV: installation location

The indoor unit is generally required to be 1.8-2.2m away from the ground, and there shall be no obstacles within 60cm of the air outlet of the internal unit. At the same time, there are also requirements for outdoor units. Outdoor units shall try to avoid places with heavy oil smoke, windy sand, direct sunlight, poor heat dissipation or high-temperature heat source, as well as hidden dangers such as easy leakage of flammable gas, strong corrosive gas, artificial strong electricity or direct effect of magnetic field. The distance between the bottom of the central air conditioning installation frame and the ground shall be greater than 2.5m, and the self-made partition shall be covered when landing directly It shall be away from the metal mesh cover to make it hard for children to touch. If it is installed under the windowsill, it shall not be higher than the windowsill; the mounting bracket shall have the operation space convenient for safe installation and maintenance.

盈彩厅Hidden danger 5: noise

During the installation, if the wall panel of the internal machine is not nailed firmly and the internal machine is not fixed, it is easy to cause excessive noise. In this case, it is easy for the installation personnel to find out and correct the problem through trial operation. At the same time, the dust of the condenser of the filter screen evaporator is dirty and blocked, and the air supply is not smooth, which will cause the air supply noise to increase. The system runs without fluorine, which will cause abnormal noise of compressor. Therefore, after a long period of idle air conditioning, before using the air conditioning, the air conditioning should be thoroughly cleaned, and at the same time, the indoor environment is also healthy.
