1. Air quality

冬季我們很少開窗通風換氣，所以通風管道中很容易積塵，如：毛發以及皮屑，從室外帶來的灰塵和污物，從衣服和地毯上脫落的細毛，蜘蛛、甲蟲等蟲子，建筑和裝修垃圾，甚至還會有小老鼠的尸體等等。而這些東西如果不用特殊的設備是不可能清理出來的，而暖風爐的過濾網的作用很有限，它不能阻止灰塵和細毛在室內循環。

In winter, we seldom open windows for ventilation, so it's easy for dust to accumulate in the ventilation ducts, such as hair and dander, dust and dirt brought from outside, fine hair falling off clothes and carpets, insects such as spiders and beetles, construction and decoration garbage, and even the bodies of mice. It is impossible to clean these things without special equipment, and the function of the filter screen of the heater is very limited, it can not prevent the dust and fine hair from circulating indoors.

2.家庭健康

2. Family health

如果長期的不清理通風管道，在管道里可能會滋生很多的霉菌和細菌等，而這些臟東西非常容易影響老人和兒童的健康。如果家中有患有哮喘或是過敏等癥狀的人，那么如果室內空氣過臟，這可能會加劇病情。

If the ventilation duct is not cleaned for a long time, a lot of molds and bacteria may grow in the duct, and these dirty things are very easy to affect the health of the elderly and children. If you have asthma or allergies in your home, if the indoor air is too dirty, it may aggravate the disease.

3.空調效率

3. Air conditioning efficiency

長期不清理空調通風管道或是更換空氣濾芯會大大的降低空調的工作效率，研究證明在線圈上如果積累有1.6毫米的灰塵就可以使設備效率降低21%。不僅如此，大量的灰塵和雜質還會大大的減少冷暖氣器的使用壽命，要知道維修或更換冷暖氣的費用是非常的昂貴的。

It is proved that if there is 1.6 mm dust accumulated on the coil, the efficiency of the equipment can be reduced by 21%. Not only that, a lot of dust and impurities will greatly reduce the service life of the heater and cooler, we should know that the cost of maintenance or replacement of the heater and cooler is very expensive.

多久要清理一次通風管道呢?

How often do I have to clean the ventilation ducts?

一般來說管道清潔需要1到2年清理一次，但是如果您的家中有老人或者是小孩，或是您家中有寵物的話，那么更好還是每年都要清理。每一年的時間節點應選擇在換季的時候，一般要在春節或者是秋季為佳。如果您剛剛交接完新房，或是房屋室內剛剛裝修完，那么做一次管道清潔也是非常有必要的。

Generally speaking, pipe cleaning needs to be done once a year or two, but if you have old people or children in your home, or pets in your home, it's better to clean them every year. The time node of each year should be selected in the season, generally in the Spring Festival or autumn is better. If you have just finished the handover of a new house, or the interior of the house has just been decorated, it is also very necessary to do a pipe cleaning.

如何清潔通風管道?

How to clean the ventilation duct?

清潔工作人員會開專用的清潔車輛上門，進門后，清潔師傅會確定所有空調出風和回風口的位置，并把外罩拆下。

The cleaning staff will open the door of the special cleaning vehicle. After entering the door, the cleaning master will determine the location of the air outlet and return outlet of all air conditioners, and remove the cover.

然后會根據風口的位置來布線。通常情況下，清潔師傅會在您家的主要管道上打個口，但如果您家之前做過管道清潔，則無需開新口。之后使用軟管將您家中的通風管道與車上的大功率吸塵器相連接，另外一個則用高壓噴槍把風口的灰塵往管道里面吹，將管道內的臟東西全部的吸入車內的收集袋中。

Then the wiring will be based on the position of the air outlet. Usually, the cleaner will make a hole in the main pipe of your home, but if your home has done pipe cleaning before, there is no need to open a new hole. After that, use a hose to connect the ventilation duct of your home with the high-power vacuum cleaner on the car. The other uses a high-pressure spray gun to blow the dust from the tuyere into the duct and suck all the dirt in the duct into the collection bag in the car.

每個出風口都會用專用的工具清理。在清理的過程中，他們會有探頭伸到管道里面，以便于觀察清理情況。等把您家的管道清潔完后，建議您更換家中的空調過濾網。

Each air outlet will be cleaned with special tools. In the process of cleaning, they will have a probe into the pipe to observe the cleaning. After cleaning the pipes in your home, it is recommended that you replace the air conditioning filter in your home.

清潔通風管道的費用，清潔公司會根據您家的面積以及風口的數量而定價。呼吸道健康是很要的哦.
