REMKO - Cooling load calculation
Calculate the appropriate performance for your air conditioner
1. All windows and doors exposed to the sun
| Sky Direction | Sun Protection | Window Surface Area | Cooling Load | |||
|---|---|---|---|---|---|---|
| South; Southeast | m2 | = | W | |||
| Southwest; Northwest | m2 | = | W | |||
| East | m2 | = | W | |||
| Northeast | m2 | = | W | |||
| West | m2 | = | W | |||
| North | m2 | = | W | |||
| Skylight window | m2 | = | W | |||
| *Use only the direction of the sky with the highest value | Total | W | ||||
2. All windows and doors not covered by point 1

Note
The temperature difference between outside and inside temperature is approx. 6-8 k. The total cooling capacity includes 30% power for dehumidification. The calculation only returns an approximate indication for the required total cooling performance and does not claim to be accurate. The values determined should be checked by a specialist planner. REMKO does not guarantee the accuracy of the values.
