Calculating power use of air conditioning?

[3azeez]

Hello everyone,

I am trying to approximate the power energy use of air conditioning under certain conditions and assumptions. I would appreciate any help possible.

The assumptions that I have put are as follows:

Air conditioning equipment: for now lets say Window 2.5 TR, Split 2.5 TR, Central 15 TR, Chiller 30 TR.
Refrigerant in use: ***** 22
Ambient temperature: variable over 24 hours of the day, I have assumptions.
Length of operation: 24 hours

Is there some tool that I can use to calculate the power energy use? A formula?

Truly appreciate your help and hope to hear from you soon.

Regards,
