Time Factor when determining AC capacity

[nevinjohn]

When designing a room for 23 deg C, against the ambient of 52 deg C, how can we estimate the time required to cool down the room to 23 at the first place?

Similarly, the other way around for heat gain.
Let’s say the room is at 23 deg C. If the AC fails, how long would it take for the room temperature to shoot up?

How can I take into account of time in heat transfer? LMTD?

Hi
When you design air condition system
Your load is :
Losing heat from building
Heat comes from machinery
Heat comes from people are working
Heat comes from changing weather
Heat comes from lighting system
Normally it is for one hour

Didn’t read fully, maybe this helps.
I would have thought insulation, windows, humidity & mentioned in previous posts could influence things.
52 degC very high for indoor & outdoor unit, which would have to be checked out.
