1、 Reasons for making central air conditioning manhole
The central air conditioner has a maintenance opening to facilitate the later operation and maintenance of the air conditioner. The internal unit of the central air conditioner is installed in the ceiling, and the main parts are concentrated in the electrical box of the internal unit. There is no manhole. If there is a problem in the air conditioner and it needs to be repaired, the ceiling must be removed. The maintenance is troublesome and causes great damage to the house. There is an access hole. If there is a problem with the air conditioner, you can check the electrical box through the access hole and manually adjust the machine components.
2、 Precautions for reservation of central air conditioning manhole
1. The size of central air conditioning manhole is generally 400mm * 400mm, and the manhole material is preferably ABS material. The traditional aluminum alloy needs welding, while the gypsum material is too hard, fragile and bulky to install. ABS material has good flexibility, long service life, no deformation and can be disassembled and washed. It is very suitable for use as manhole material.
2. The central air conditioning manhole is generally located on the left side of the air outlet or directly below the electrical box. If the size of the return air outlet is sufficient, the return air outlet can also be used as an manhole, so it is not necessary to leave an manhole. The setting of manhole is not limited to one position, but shall be designed according to the actual situation.
3. Generally, the manhole needs to be sealed invisibly. If the return air outlet is also used as the manhole, it does not need to be sealed.
4. The decoration party shall be responsible for the opening of the manhole, and the air conditioning construction unit shall be responsible for installing the filter screen and sealing. The air conditioning construction party shall pay attention to whether the opening of the decoration party meets the requirements.
5. It is better not to put tall objects that hinder maintenance under the manhole, such as wardrobe, bookshelf, etc.
In short, the central air conditioning manhole facilitates the later maintenance of the air conditioner, which must be reserved. Be sure to pay attention to the above 5 points when reserving the position of the manhole to avoid unnecessary trouble in the future.
