how can i calculate the horse power air conditioning for 1 room size 30 feet x 30 feet x 8 feet in malaysia?

Question

formula pls

Answer 1

Normally by guesswork, a room of 12'x12'x10'=144 cu. ft would require 1hp a/c. For your 7200 cu. ft room maybe would require about 50hp. That's my estimate.
Have a try and good luck.
