Example: Equipment selection based on system load profile
Since the five rooms on the 4th floor face different directions, their hourly cooling load profile will also be different.
We select each indoor unit based on the individual room peak load. However, we need to use the total load profile
on the 4th floor as a base to choose the outdoor module.
Load in each room Total load in all rooms of 4th floor
1. The total load on the 4th floor is calculated by
adding up the hourly cooling loads of the five
rooms.
2. The maximum value of the total load is used to
select the outdoor module.
