Question: before turning on air conditioning, just clean the filter net with detergent and water, why still be like this? expert dispel doubt: after air conditioning is used for a period of time, the outside cover, filter net surface has the dust that deposit and dirt, very easy to clean. But the most concentrated part of air conditioning bacteria, the radiator, is often ignored. As the core part of air conditioning cold and heat exchange, heat sink not only accumulates dirt and dust, but also breeds a large number of bacteria under the action of condensate water. Add air conditioning, usually close doors and windows, air circulation, especially hot and humid summer, germs are more likely to breed. A few days ago, the China CDC, the Shanghai CDC, the Fudan University School of Public Health, and other institutions conducted a field survey of household air conditioners in Shanghai, Beijing and Shenzhen, and found that the total bacterial count of 10% of the air conditioning radiators exceeded the standard. The total number of mold in 84% of the air-conditioned radiators was over the standard, and the highest number of bacteria detected in the air-conditioned radiators was more than 1000 times. Air conditioning in addition to the adsorption of a large number of dust, there are mites, bacteria, fungi and other pathogenic bacteria. When running, the internal air conditioning, especially the radiator of bacteria, fungi with the vent, with the respiratory tract into the human body, easily lead to dizziness and fatigue, and even suffer from cold, rhinitis, asthma and other respiratory diseases. Therefore, many air conditioning diseases are not only caused by alternate heat and cold, air conditioning pollution is also a source of disaster. How many sources of pollution are hidden in domestic air conditioners? as for the frequency of cleaning air conditioning radiators, during the spring and summer seasons, it is necessary to thoroughly clean and sterilize air conditioners before turning on the air conditions.In summer, air conditioners are frequently used and it is recommended that families with conditions be able to do so. Clean air conditioning once a month to avoid air conditioning pollution. Installation of fresh air system is urgent in addition, outdoor pollution will enter the room. There will be pollutants on the dust and radiators in the home. The general air conditioning will not remove PM2.5,. In addition to regular cleaning, the key is good ventilation in the bedroom. At this stage, the outdoor air quality in many cities is not optimistic. Installation of the fresh air system may not be delayed. Many fresh air systems now have heat exchangers that turn on central air conditioning while starting fresh air systems that not only update indoor air freshness without windows but also reduce energy consumption. When the fresh air system is in operation, the temperature of the imported outdoor air is adjusted to minimize the indoor air temperature difference of the indoor fresh air temperature. It not only can recover the loss of indoor cooling (heat), but also can effectively reduce the energy consumption of air conditioning and save more energy. What is the difference between a central air conditioner with a "fresh air function" and a central air conditioning system with a "fresh air function"? The main function of air conditioning is to adjust the temperature. Its "fresh air function" is to draw in the outdoor air through the air inlet through a rough line of filtration, cooling or heating the air to the indoor, the return air will be the indoor dirty air back is still an indoor cycle. The fresh air system passes through the fresh air unit, the fresh air pipe and the tuyere, sends the outdoor air into the indoor, then passes through the tuyere, the exhaust air pipe and the fan to discharge the indoor air outdoors. Simply put, the fresh air system is through the ventilation, the turbid indoor air will be discharged out, the outdoor fresh air will be brought in to realize the circulation of indoor and outdoor air. In summer, in the case of 24-hour closed doors and windows, the use of air conditioning and fresh air system, indoor can also be maintained in the body's comfortable temperature, and the air clean, fresh. In the premise of opening windows in order to achieve a good replacement of indoor air, indoor air system and air conditioning can be used at the same time, cooling, health! Ann

疑问：开空调前，刚把过滤网用洗洁精和水刷干净了，为什么还会这样？

专家释疑：空调使用一段时间后，外罩、过滤网表面就有沉积的灰尘和污垢，很容易清洗。但空调细菌最多聚集的部位——散热片却常常被忽视。

作为空调冷热交换的核心部件，散热片除积聚污垢灰尘外，还会在冷凝水作用下滋生大量病菌。加上开空调时，通常会紧闭门窗，空气不流通，特别是夏天闷热潮湿，病菌更易滋生。



日前，中国疾控中心、上海市疾控中心、复旦大学公共卫生学院等机构对上海、北京、深圳进行实地家用空调入户调研发现：88%的空调散热片细菌总数超标，84%的空调散热片霉菌总数超标；空调散热片中检出细菌超标最高可达1000倍以上。

空调除了吸附大量的灰尘外，还有螨虫、细菌、真菌等致病菌。运转时，空调内部，特别是散热片的细菌、真菌随出风口喷出，随呼吸道进入人体，容易导致人体出现头晕乏力，甚至患上感冒、鼻炎、哮喘等呼吸道疾病。因此，很多空调病不只是冷热交替造成的，空调里的污染也是祸源。


家用空调里究竟暗藏多少污染源？

至于空调散热片清洗的频度，春夏换季时，需要开启空调前，应该彻底清洗消毒一次；夏季，空调使用频繁，建议有条件的家庭，每月清洗一次空调，可避免空调污染。
安装新风系统已经刻不容缓

此外，室外有的污染都会进入室内。家中尘埃，散热片上面都会有污染物，一般的空调不会去除PM2.5，除了定期清洁空调，关键还要靠居室良好的通风,现阶段很多城市的室外空气质量也不容乐观，安装新风系统可能已经刻不容缓。

而现在很多新风系统带有热交换器,开启中央空调的同时启动新风系统不仅在不开窗时更新室内空气清新度,同时更减少能源损耗。

新风系统运行时对引入的室外空气的温度进行调节,使引入室内的新风温度室内的空气温差减到最小。不仅在通风换气的同时可以回收室内冷(热)量的损失,还能有效地减少空调的能耗,节省更多能源。

带“新风功能”的中央空调和新风系统

带“新风功能”的中央空调和新风系统有什么区别？

中央空调的“新风功能”，注意只是辅助功能，不是主要功能，空调的主要功能都是调节温度。它的“新风功能”是通过进风口把室外的空气抽进来经过一遍粗线条地过滤，将制冷或加热后的空气送到室内，回风囗则将室内污浊的空气吸回去仍旧是室内循环。

新风系统是通过新风机组、新风管道和风口，将室外的空气送入室内，再通过风口、排风管道和风机将室内的空气排出室外。简单地说，新风系统就是通过换气，将浑浊的室内空气排出去，将室外新鲜空气引进来，实现室内外空气的循环。

夏天，在24小时紧闭门窗的情况下，同时使用空调和新风系统,室内也可以直保持在人体舒适的温度,而且空气干净、清爽。在不开窗户的前提下为实现室内空气的良好置换，室内可以同时使用新风系统和空调，降温、健康两不误!
