Hello everyone,
We renovated an older building to a KfW-55 standard house (on paper). In reality, it almost meets KfW-40.
Today, the tenant in the attic informed us that the room temperature is about 31°C (88°F). During the renovation, we already made provisions (empty conduits, connections...) for an air conditioning system.
How large would you size an air conditioner? Attached is a floor plan of the attic. Living room = 26m² (280 sq ft) with a volume of 70m³ (2,470 cu ft), where the partial wall in the hallway does not reach the ceiling due to the sloped roof. This allows air circulation to the hallway and kitchen.
I have noted the following performance differences in Bosch air conditioning units:
Climate 3000 26WE
Design cooling capacity 2.8 kW
SCOP (Seasonal Coefficient of Performance) moderate climate 4.1
Nominal airflow (indoor) 520 Nm³/h
Climate 3000 35WE
Design cooling capacity 3.6 kW
SCOP moderate climate 4.2
Nominal airflow (indoor) 530 Nm³/h
Climate 3000 53WE
Design cooling capacity 5.3 kW
SCOP moderate climate 4.0
Nominal airflow (indoor) 800 Nm³/h
Climate 8000 35WE
Design cooling capacity 3.5 kW
SCOP moderate climate 5.1
Nominal airflow (indoor) 851 Nm³/h

Do I understand correctly that the device can draw a maximum of 2000W of power? The 3.5kW is only the theoretical cooling capacity.
At 3.5kW (design or nominal capacity), the device would consume 780W.
The cooling capacity would range from 0.9kW (minimum) up to 4.2kW (above nominal capacity). It is likely that at 4.2kW it would draw the full 2000W.
