一、检查安装位置是否恰当

First, check the location of the installation is appropriate

家用中央空调安装位置是非常考究，没装好会造成以后的维修或者空调制冷/制热效果不佳。室内外机的安装必须水平、牢固，当有较多室外机连接在一起时必须排放准齐、间距均匀，朝向一致，高低协调。

The installation of the household central air conditioning is very sophisticated. If it is not installed, it will cause future maintenance or air conditioning refrigeration / heating effect is not good. The installation of indoor and outdoor machines must be level and firm. When there are more outdoor units connected together, they must be evenly distributed, uniformly spaced and aligned.

室外机要使用膨胀螺栓固定在水泥墩上，或者固定在用槽钢做成的底座上，还要避开油烟重、风沙大、阳光直射等地方，装置支架要有便于平安装置和维修的操作空间。

The outdoor machine should be fixed on the cement pier with the expansion bolt, or fixed to the base made of channel steel, and also to avoid the heavy oil smoke, the wind sand, the direct sunlight and so on. The device support should be convenient for the safety and maintenance of the operating space.

二、查看管线安装是否规范

Two, check whether the pipeline installation is standard

安装中央空调时使用的钢管、水管、信号线管、电源线管的走向要横平竖直。为了确保使用效果，每个独立的冷媒系统的实际配管长度、等效配管长度、室内机与室外机、室内机与室内机之间的高低差，分支以后的配管长度、冷媒分支及配管的选择都必须严格遵循有关规定进行。

When the central air conditioning is installed, the direction of steel pipe, water pipe, signal line and power line should be horizontal and vertical. In order to ensure the use effect, the actual pipe length of each independent refrigerant system, the equivalent pipe length, the indoor machine and the outdoor machine, the indoor machine and the indoor machine, the length of the piping, the branch of the refrigerant and the selection of the piping must be strictly followed.

室外机电源线为三相五线制，室内机电源线为单相三线制，室内外机的电源线只可以使用铜线，其允许通过的电流必须大于或等于其正常工作时的额定电流。在同一系统中，可以只使用一个电源开关，但必须严格选择开关可断路器的容量规格，配电施工中所使用的部件和材料以及电器作业都必须符合当地法规。室内外机必须可靠接地，室内外机的电源线宜采用铜管保护，在离机器很近的地方用橡皮金属软管与机器连接。

The power line of the outdoor machine is three phase five wire system. The power line of the indoor machine is single phase and three wire. The power line of the indoor and outdoor machine can only use copper wire. Its allowed current must be greater than or equal to its normal operating current rating. In the same system, only one power switch can be used, but the capacity specifications of the switch circuit breaker must be strictly selected. The components and materials used in the distribution construction and the electrical work must conform to the local regulations. The indoor and outdoor machines must be reliably grounded. The power line of indoor and outdoor computers should be protected by copper tubes, and the rubber metal hose will be connected to the machine near the machine.

三、注意用材是否符合要求

Three. Pay attention to the requirements of the material

安装中央空调的时候所使用的材料都要具有一定的防腐作用，排风管道必须采用不燃材料或者是难燃材料，空调配件不得使用对人体有害的材料。安装家用中央空调的辅助材料有很多，铜管，水管，线号管，排水管，电源线等等一系列的安装材料。

The materials used in the installation of central air conditioning should have a certain antiseptic effect, the exhaust pipe must adopt non combustible material or refractory material, and the air conditioning accessories must not use the harmful material to the human body. There are many auxiliary materials for installing household central air conditioning, such as copper tube, water pipe, line number pipe, drain pipe, power cord and so on.

四、测试效果是否达标

Four. Whether the test results can reach the standard

家用中央空调工程安装后要进行效果测试，包括中央空调出风口是否有冷/热风的放送，同时要记录中央空调每隔两个小时的温度变化，这样的调试才更科学和客观。另外还需要测试噪音情况。如果噪音过大，就很可能是装置不当造成的。

After the installation of the central air conditioning project, the effect test should be carried out, including the cooling / hot air release of the central air conditioning outlet, and the change of the temperature of the central air conditioner every two hours. This is more scientific and objective. It also needs to test the noise. If the noise is too large, it will probably be caused by improper installation.
