Note: refer to It is cited from Design and Troubleshooting for Heating and Cooling Air
Conditioners.
(1)Take the lower limit when the total building area is less than 5000m
2
and take the upper
limit when the total building area is large than 10000 m

.
(2)The estimated load is directly indicates the required capacity of the air conditioners.
(3)Unless otherwise stated, the area always indicates the total building area no matter if air
conditioning is for local area or not.
3.6.1.2 Calculation of Indoor Load Demand
Indoor load demand = room area (㎡)× per unit load(W/㎡)
Note: our products that will be selected with cooling loads should fit for the on-site situation.
3.6.1.3 Selection of a Terminal Unit
Select a proper terminal unit in accordance with requirements on load noise and installation
space.
3.6.1.4 Selection of a Main Unit
A main unit should be selected based on its theoretically calculated cooling load.
3.6.1.5 Calculation of Heating Load
Calculate the heating loads of the main unit and terminal unit that have been selected, which
is not expected to be recognized until satisfying the requirements.
