中央空调末端设备是风机盘管，不管是明装还是暗装，先确定好风机盘管位置和出风口位置、回风口位置，在确定管道的位置及走向，最近、弯路越少越好，和主管道连接完成即可。风机盘管的进出水口安装软管、阀门、电磁阀，过滤器看图纸要求。风口离机子远的要加风管（出风管要保温）、帆布软连接。内机就位：施工队进场第一步就是吊装内机，这里只要注意2个点就可以避免后续问题。 a:：内机离房顶距离不得小于1公分，避免机器运行时与墙顶产生共振。 b：内机吊装需考虑千分之五的坡度，接冷凝水的一侧要稍微低一些，避免冷凝水排不出去。冷媒铜管的安装：安装完内机即可安装冷媒铜管，这是中央空调安装过程中最重要的一个环节。 a：所有的焊接点应该是铜管与分歧管的连接处进行焊接，不存在铜管与铜管焊接。 b：在焊接过程中必须在铜管内冲入氮气（充氮焊接工艺），这使铜管内部没有空气避免了产生焊接使内壁结炭从而在正式运转时入压缩机而产生故障。 c：焊接完成后应该用高压氮气进行管内*灰，保持铜管内清洁。充氮保压：这是焊接完成后必须对铜管进行的压力测试，往铜管内充入一定压力的氮气进行保压，一般压力测试时间为24小时。需要特别说明：使用R410冷媒，需保持管内压力为40公斤，R22冷媒则需要保持管内压力为20公斤。氮气是惰性气体，膨胀系数小，几乎不存在由于热胀冷缩而产生的压力变化。如果测试过程中压力表有下降，则应该检查冷媒管焊接是否有问题。冷凝水管的安装：冷凝水管从内机接出后至室外或地漏，至少保持>1%的坡度。质量较高的安装则是从室内机接出后，就近落地，最后会同其他冷凝水管一起接出室外或地漏。安装外机：做到外机风扇出风口必须在50公分内无遮挡物，所有落地脚必须安装*垫，保证外机运转正常抽真空：外机安装完毕后在充填冷媒前需要对冷媒管进行抽真空，把管内的空气抽出，保持管内干燥、无水分，否则空气和水会与冷媒混合产生冰晶，严重的会造成设备损坏。规范：冷媒管需要连接上外机后进行*作；抽真空的时间一般多联机不少于两小时，一拖一风管机不少于20分钟。充注冷媒：上述工作完成后，则可以开启冷媒阀，释放出外机内自带的冷媒，开机测试并检测压力，适当进行补充，直至调试完成，达到理想工作状态后即可。风口测量安装：回风口：家庭中央空调通常将回风口与检修口安装在一起，风口尺寸必须与内机回风口吻合，不能出现错位情况，这样才可以达到最佳回风量；并保证有足够的维修空间。出风口：出风口一定不能装在灯带附近（理由：如果出风口前有灯带，会造成空调在制热时遮挡出风，而热空气是往上的，使得热空气滞留房间的上部，从而整个活动空间感觉热量不足，需很长时间才能有热感觉。）

一般形式的中央空调，要安装在吊顶内，如果你家做了吊顶，需要局部拆改，如果只是做了踢脚线，可能简单一点。现在中央空调也有壁挂式的，但是走管可能费点劲，优点是省电。以上的内容仅供参考，希望能够帮到您。

房子的面积是不是够大要是120平米以上的房子就有些必要，不过装中央空调室内高度要求很严，最好是有打吊顶的房子，比如吊顶留有的空间最少要能放入一台风几盘管，所以房高很重要，还要布线走线需要挖墙埋管总之不算简单，还有你需要安装什么样的中央空调，如果房子大就需要按水冷冷水的空调，如果房子小就要风冷冷风就可以了，房屋比较多也是安装中央空调的首选，因为装小壁挂会影响房子的整体外观外挂机，会比较多不好看，还有就是中央空调是中央管理集中控制的，用起来还是比较方便，至于输出的冷量和壁挂空调，一拖多空调差不过没什么大致上的分别，只要算好你屋子的平米数需要选用多大的空调就可以了，中央空调当然也有它的不足之处，比较爱漏水风机盘管如果上时间不保养冷凝水下水脏堵，就会漏水有可能家里没人就会把顶子给泡了，如果不是很大的房子或房屋很多的话，你就不要选择中央空调了，用壁挂机或柜机或一拖多等也都是可以的- -
