Regarding the installation of central air conditioning, there is such a saying in the industry that "three points of equipment, seven points of installation". Central air conditioning as a whole house integrated system, every link must be carefully installed, so as not to affect the subsequent use of the effect. Today, the HVAC clean room design and installation Xiaobian will introduce the central air conditioning positioning, installation and acceptance standards, hoping that the clean workshop design and installation manufacturers can bring some help to the families who install central air conditioning.

1. The so-called positioning is the location of the specified central air conditioning outlet and return air outlet. The outlet of the restaurant is usually installed in the aisle, and the outlet of the bedroom is usually installed near the door, and the outlet is divided into two kinds of book air supply and top air supply. If the air flow of the outlet can be blown to the constant amount or the top, move down as far as possible to avoid the occurrence of direct blowing of the body. In addition, when installing the central air conditioning indoor unit, pay attention to leaving a little space for maintenance.

2. When selecting the position of the air outlet, pay attention to the surrounding obstacles to block the air circulation; Side air supply or top air supply is not necessary to be too entangled, mainly determined by your home ceiling, but pay attention to the coordination of the decoration is better.

First of all, it is not recommended to install central air conditioning in houses with floors lower than 2.7m, and it is not recommended to use ceiling lights in houses with central air conditioning of 2.7m~3m. Otherwise, the room will feel oppressive. The installation work is handed over to a professional installation company, and the specific installation steps are not understandable to the general public, we only need to do a good job of acceptance.

The installation of the central air conditioner is a hidden project. The indoor unit, refrigeration pipe, condensation pipe, air pipe and wire pipe are concealed in the sandwich of the ceiling through the ceiling device, and only the air supply port and the return air port are leaked out externally. Pay attention to these points after the completion of the decoration;

At the time of acceptance, the installation personnel are required to test the power supply, and the regular installation company will check the power cord before installation, and the power cord does not meet the safety standards. This situation is informed to the owner prior to installation.

Step 2 Leak

After installation, it is necessary to run immediately to monitor whether water leakage, if no water leakage is found for a certain period of time, there will be no water leakage in the future. If there is water leakage, it is easy to cause the phenomenon of suspended ceiling bubble water, and the follow-up maintenance is a big project. Be sure to check well in advance. In this regard, Hitachi central air conditioning has done a better job, using the condensate lift pump and the alarm shutdown mechanism. First of all, a condensate lifting pump will be installed during installation, and the condensate will be lifted to a high level and then discharged through the drain pipe without increasing the thickness of the ceiling. Then, a device called float switch is installed inside the system, its role is to alarm before the water level rises to a dangerous position leading to water leakage, remind the user that the condensate discharge pipe is not smooth, and automatically shut down, double insurance to solve the problem of water leakage bubble top, expensive reason ah.)

3. Leakage of fluorine

Fluorine leakage of central air conditioning is a headache. In the acceptance stage, you can apply soapy water to the four interfaces of the indoor unit of the air conditioning pipeline and the valve port of the globe valve and other places that are prone to fluorine leakage, observe for 5 minutes, if there are bubbles formed, it indicates fluorine leakage, if not, it is considered qualified.

4. Running noise

The ideal noise of central air conditioning operation should be controlled within 20 decibels, if the operation noise is too large, it is not ruled out that the product is a problem, but most of the installation problems, such as the indoor unit is not fixed, this situation can be remedied in time through indoor debugging.
