对于吊顶内风机盘管的过滤器最好安装于集水盘内，便于拆洗。如集水盘不够大可要求生产厂家适当加大；如做不到这点，那么在保温时，过滤器堵盖部分应做成可拆式保温，便于以后维护中拆洗过滤器。应考虑在管网最低处设置大口径排污阀，便于清洗时排污。如果设计上在管网顶部采用自动空调排气阀，施工单位在管网清洗前不要急于把排气阀安装上去，这样便于注水时满灌及排污时将管内水尽快排净。
For ceiling fan coil filter best installed in the water collecting tray, easy to take apart and wash. As a water collecting disc is not big enough to require manufacturers to increase; if not, then in the insulation, the filter cover part should be made detachable insulation, convenient for later maintenance washable filter. Consideration should be given to large aperture discharge valve is arranged in the pipe network the lowest, sewage is convenient for cleaning. If the design in network with automatic air exhaust valve at the top, the construction units in the network before cleaning not to rush to exhaust valve installed, so that water is full irrigation and sewage will soon drain tube.
对主要设备的进、出水管间可安装短路阀，冲洗时关闭进、出水阀，打开短路阀即可对整个管网进行系统冲洗。而对于末端装置是风机盘管，由于安装空间原因安装短路阀会有困难，可在供、回水干管上考虑便于冲洗的措施。如在空调供水干管末端及回水干管首端设置冲洗阀，对供水和回水的水平干管分别冲洗，冲洗时注意冲洗方向应与系统运行时水流方向一致。
The main equipment, pipe can be installed into the short circuit valve, flushing inlet, outlet valve, open circuit valve can be on the whole network system flushing. The terminal device is fan coil, the installation space causes short circuit valve installation is difficult, in supply, return water pipes to consider easy flushing measures. As in air conditioning water dry pipe end and return water pipe is arranged on the head end of the flush valve, water supply and return water level pipe flushing flushing flushing respectively, when the attention direction and operation of the system when the water flow direction.
避免因冷热水污染堵塞末端装置和腐蚀管道。对于冷冻水系统，从设计上最好考虑安装电子除垢装置，并对水质每年作稳定处理，对冷却水系统也应每年进行水质处理。在主要设备及末端装置上空调进水管上设过滤器，避免管网内杂物进入设备及末端装置，引起堵塞报废。
Avoid plugging terminal device and corrosion of pipes for hot and cold water pollution. The chilled water system, installed electronic descaling device considering the design the best, and the water each year is stabilized, the cooling water system should also be a year for water treatment. In the main equipment and terminal device on the air inlet filter set, avoid the pipe network within the debris into the equipment and terminal device, causing clogging scrap.
