What is the ceiling size of home central air conditioner?

Height of ceiling of household central air conditioner:

The installation height of ceiling of household central air conditioner is determined according to the thickness of air conditioning pipeline, drainage space and indoor unit of household central air conditioner, mainly based on the indoor unit thickness of household central air conditioner. The general installation step is to install the pipes and drainage slopes of the household central air conditioner to make them as close as possible to the ceiling wall, and then determine the ceiling thickness of the household central air conditioner according to the thickness of the indoor unit.

For example, if the indoor unit thickness of household central air conditioner is 200mm, and the pipe thickness and drainage space are 125mm, then the size of 625mm needs to be reserved for installing household central air conditioner. Although different brands of indoor units have different thicknesses, the slopes of pipes and drainage are roughly the same, so the size of household central air conditioner to be used should be determined before making the ceiling.
