Sizing an air conditioner for Indian conditions

Sizing an air conditioner

Recently I read in an Indian HVAC magazine the following.

0.5 TR AC for upto 250 sft(25 SQM),
1 TR Ac for upto 550 sft(55 sqm), and
2 TR for upto 1400 sft (140 sqm).

Is it not very surprising? For, this one seems to be addressing residences!

Even in a multistoried complex, with all the floors conditioned, these figures are going to be impossible to achieve.

I feel the data would be correct if it reads like:

With Indian ambient conditions, 0.5 TR is ruled out for many applications. Hence,

1 TR for up to 120-200sft,
1.5 TR for up to 150-250 sft &
2 TR for upto 200-300 sft!

depending upon other factors.
