中央空调清洗，一种对中央空调系统整体进行清洗除尘清洗方案。中央空调清洗范围包括：通风管道、风机盘管、主机、水系统、风柜、冷却塔清洗等。

　　清洗前，清洗施工单位应根据空调系统情况和卫生学评价报告的要求，需要查阅有关技术资料并对需要清洗的空调系统进行全面勘察和检查，确定适合的清洗方法、清洗工具和设备，订立清洗方案。

　　1、商用中央空调系统的清洁过程

　　首先在风管适当部位开两个施工孔（用于放置摄像机器人、封堵气囊等），在两开孔位置外侧用封堵气囊堵住管道两端。再用软管将集尘器连接到其中一个施工孔，使风管内产生负压气流，让灰尘与污物被吸入集尘器内，选择适当的清洗毛刷，用软轴毛刷进行管道壁清洗。清洗以后，放入摄像机器人拍照记录，确认清洗质量。得到认可后，在清洗过的管道内喷洒消毒剂。最后，再用相同材料重新封闭开口处，定期清洗商用中央空调，不仅可以减少空调的耗电量，还可延长其使用寿命，而不按标准清洗的商用中央空调比清洗后的中央空调耗电量要增加很多，消费者应严谨以上商用中央空调清洁四大误区，正确合理的清洗商用中央空调，重视清洁和消毒，不要让它成为你的健康隐患。

接下来，由有资质的检测机构按相关国家标准检验清洗质量，并检测风管清洗消毒后的空气质量，根据施工详细记录整理出报告呈送给客户，至此，清洗工作全部完成。

　　室内、外机的清洁工作相对简单。室内机：把风口拆开，将滤网取下来，用水和毛刷或高压水枪将滤网清洗干净，待晾干后，重新装回即可。冷凝器的清洁同分体式空调类似，需要用专用的清洁剂。室外机：用高压水枪自上而下彻底清洗主机散热片上的污垢即可。

2、家用中央空调的清洁

　　按中央空调清洗的洁净度的不同，可以把空气净化标准分为以下三种。

　　1。一般净化：它常用于一般的舒适性空间，采用初效过滤器一次处理，无具体的净化要求。

　　2。中等净化：用于对室内空气悬浮微粒的质量浓度有一定要求的空间，比如大型公共建筑物内，空气中的悬浮微粒的质量浓度应不大于一立方零点一五毫克。在这些场合，应首先采用初效过滤器过滤后，再用中效过滤器。

　　3。超净净化：这种常用于电子产品生产、精密零件加工车间等。这种场合应先用初效过滤器，再用中效过滤器，最后用高效过滤器进行净化。

Central air-conditioning cleaning, a central air conditioning system as a whole cleaning dust removal cleaning program. The cleaning scope of central air conditioning includes ventilation duct, fan coil unit, main engine, water system, wind cabinet, cooling tower cleaning and so on.

Before cleaning, the cleaning construction unit should consult the relevant technical data according to the condition of the air conditioning system and the requirements of hygienic evaluation report, make a comprehensive survey and check on the air conditioning system that needs to be cleaned, determine the suitable cleaning methods, cleaning tools and equipment, and conclude the case of cleaning.

1. The cleaning process of the commercial central air conditioning system

First, two construction holes are opened in the proper part of the wind pipe (used for placing the camera robot, sealing the air bag, etc.), and blocking both ends of the pipe with an airbag on the outside of the two opening position. Use the hose to connect the dust collector to one of the construction holes, make the air flow in the wind pipe, let the dust and the dirt be inhaled in the dust collector, choose the proper cleaning brush, and use the soft shaft brush to clean the pipe wall. After cleaning, put the camera robot to take photos and confirm the cleaning quality. After approval, disinfectant is sprayed in the cleaned pipeline. Finally, reclosing the opening with the same material and cleaning the commercial central air conditioning regularly can not only reduce the power consumption of the air conditioning, but also prolong its service life. The consumption of the commercial central air conditioning without the standard cleaning is much more than the central air conditioning after the cleaning. The consumer should be strict with the commercial central air conditioning cleaner. The four mistake is to properly and properly clean commercial central air conditioning, pay attention to cleaning and disinfection, and do not let it become a health hazard.

Next, the quality of cleaning is checked by the qualified inspection organization according to the relevant national standards, and the air quality after the cleaning and disinfection of the wind pipe is detected. The report is sent to the customer according to the detailed construction records. At this point, all the cleaning work has been completed.

The cleaning of indoor and external machines is relatively simple. Indoor machine: disconnect the tuyere, remove the filter, clean the filter with water and brush or high pressure water gun. The cleaning of condensers is similar to that of split air conditioners. Special cleaning agents are needed. Outdoor machine: thoroughly clean the dirt on the heat sink of the host machine from top to bottom with a high pressure water gun.

2, the cleaning of the household central air conditioning

According to the cleanliness of the central air-conditioning cleaning, the air purification standards can be divided into the following three categories.

1. General purify: it is usually used in the general comfort space, using the primary effect filter at once, without specific purification requirements.

2. Medium purification: space for the mass concentration of suspended particulate matter in indoor air, for example, in large public buildings, the concentration of suspended particles in the air should not be more than one cubic zero point one five milligrams. On these occasions, the first effect filter should be used first after filtration and then the medium efficiency filter.

3. Super clean purification: This is often used in the production of electronic products, precision parts processing workshop. In this case, we should first use the primary effect filter, then use the medium efficiency filter, and finally use the high efficiency filter to purify.
