2) Considerations in capacity selection
• A place of good insulation, an apartment ¡ 90~105 kcal/h/m
2
• A place of poor insulation, a slate building ¡ 135~150 kcal/h/m
2
• A place of poor insulation and many windows ¡ 150 kcal/h/m
2
or over
• A place of poor insulation, many windows, much sunshine ¡ 160 kcal/h/m
2
or over
• Western or southern room (+)
• Many persons in a room (+)
• Heater in a room (+)
3) Rough selection of capacity
Considering the above 2), add the clearance rate by 10% each except for lecture room, kitchen, or special
area, and select the capacity.
The nominal area is selected on the basis of outdoor 35°C and indoor 27°C, but actually the temperature in
condenser is higher than standard condition according to summer hottest temperature and condenser installa-
tion condition, so the capacity selection by the rough method does not matter.
