我们日常中央空调维保应该注意检查哪些方面呢？
What aspects should we pay attention to in daily maintenance of central air conditioning?
主要是以下几点：
The main points are as follows:
（一）检查电源设备
（1） Check power supply equipment
定期检查通风道是否阻塞，空调运行时声响是否正常，空调器电源插头与插座是否有无松动或脱落。
Regularly check whether the ventilation duct is blocked, whether the sound of the air conditioner is normal during operation, and whether the power plug and socket of the air conditioner are loose or detached.
（二）定期开机试运作
（2） Regular start-up and trial operation
在不使用空调的时候，至少也要保持一个月开机一次。空调运转的核心是压缩机，如果长时间不用，压缩机内润滑油可能凝结。
When not using air conditioning, it is necessary to keep it on at least once a month. The core of air conditioning operation is the compressor. If not used for a long time, the lubricating oil inside the compressor may condense.
（三）清洗过滤网
（3） Clean the filter screen
过滤网需要经常清洗，以免灰尘太多堵死出风口。清洗时，只需将过滤网抽出来，可以用吸尘器吸干净，或则用清水清洗。清洁完成，将过滤网装回空调，开风机运转约2小时，使空调器内部没有湿气。
The filter screen needs to be cleaned regularly to prevent too much dust from blocking the air outlet. When cleaning, simply pull out the filter screen and use a vacuum cleaner to clean it, or clean it with clean water. After cleaning, install the filter back into the air conditioner and turn on the fan for about 2 hours to ensure that there is no moisture inside the air conditioner.
注意：如果是用清水清洁过滤网，过滤网必须阴干后才能装入空调。
Attention: If cleaning the filter screen with clean water, the filter screen must be dried in the shade before being installed in the air conditioner.
清洗滤网的操作步骤：
Operating steps for cleaning the filter screen:
1.拆卸空调过滤网时，注意别碰到室内机组的金属部分，防止刮伤。拆下空气过滤网后，轻轻拍弹或使用电动吸尘器除尘。
When disassembling the air conditioning filter screen, be careful not to touch the metal parts of the indoor unit to prevent scratches. After removing the air filter, gently tap or use an electric vacuum cleaner to remove dust.
2.如果过滤网积尘过多，则可用水或中性洗涤剂清洗，但不得用50℃以上的热水清洗，以免变形。也不要用海绵清洁，否则会损坏过滤网表面。
If the filter screen accumulates too much dust, it can be cleaned with water or neutral detergent, but it should not be cleaned with hot water above 50 ℃ to avoid deformation. Do not use a sponge to clean, as it may damage the surface of the filter screen.
3.用清水冲洗干净后，放阴凉处吹干，千万不要在阳光下暴晒或在火炉旁烘干，因为那样可能会引起过滤网变形。
3. After rinsing with clean water, place it in a cool place and blow dry. Do not expose it to sunlight or dry it by the stove, as it may cause deformation of the filter screen.
4.将吹干后的过滤网再安装回原位置，整个清洗过程完成。
4. Install the dried filter screen back to its original position, and the entire cleaning process is completed.
