You need36 to45 ton ; in Gulf we take1 ton for each20 to25 square meter

first please tell me:

1-where is villa located?

2-is ther any other buildings side to side around it?

Please use heat load calculation software like HAP to get exact results. Load depends upon building structrue, windows, occupancy and orientation.

Considering an atmospheric peak temperature of50deg celcius u might require a52 ton machine maximum. But this is just a thumb rule, in my last project the chiller we had selected was having a tonnage of250tons at atmospheric temp of51deg celcius, the same chiller will do380 tons at atmospheric temp of37deg celcius.

In USA we use one Ton for every400 squares feet. So after converting300 meters to squares feet I come up with8 Ton for every floor that mean you will need24 ton for your building. If it does not exist in the market go with the next close number like25 Ton or even30 Ton.

 

 

 

300 Square Meters =3229.17312 Square Feet

 

 

 

One Ton for400 Square Feet

 

 

 

3229 ÷400 =8 Ton.

 

 

 

Feel free to contact me with any questions.

Roughly you need chiller around50-60 ton maximum

for a rough estimation that take the following consedration :1- highest ambient temp is45 degree celcuis

2-  building is dos't have a wide area of window or glass3- the roof is isolated4- pepole in floor are about10 -15 person

 

you may need a (50 to60 Ton Chiller ) @45 dgree condenser temp ( air cooled )

The l Heat load calculation is depend on many factors as1_ city2_ direction of building estemate heat load gain from solar through walls and through roof if exposed for outdoor or not Generaly its need to conduct heat load calculation using programs as hap or elite so can determine the load estemation then can indicate capacity of chiller required Approximatly if in ksa need to about1 ton per20_25 sq meter total about45 ton will be e
