Understanding Sizing HVAC

Hello everyone,
I’m a beginner in Ladybug Tools, so please excuse me if I’m asking a very obvious question, but I’m having trouble interpreting the usage of Ideal Air. What would be the actual capacity of the air conditioning equipment? I simulated an Ideal Air, and I noticed there’s a table called “Zone Sizing Information” which, for example, gives a value of “User Des Load” of 9983.67 W.

While in the “Component Sizing Information” table, the value for the same space in “Design Size Maximum Total Cooling Capacity [W]” is 17978.45 W, which is twice as much as the first case.

Which one should I consider for sizing my air conditioner?

I’m sorry, but I’ll take the liberty of tagging @chris and @MingboPeng to receive a response.
