Ventilation and air changes
Air changes, moisture transfer and sensible thermal load.
Inputs
- Air changes per hour
- 2 h⁻¹
- Sensible thermal load
- 3.29 kW
- Water removed by ventilation
- 6.36 l/h
- Indoor humidity ratio
- 12.9 g/kg
- Outdoor humidity ratio
- 7.41 g/kg
Ventilation does not add moisture in these conditions.

Exhaust volume flow is at indoor conditions. Positive water removal means drying; negative means added moisture. Positive heat indicates supply-air heating demand, negative cooling. Heat recovery and latent heat are excluded; this is not a full climate design.
How we calculate
ACH = Q / V [h⁻¹]; water = ṁdry × (wᵢ − wₒ) [kg/h]; heat = ṁdry × (1.006 + 1.86wₒ) × (Tᵢ − Tₒ) / 3600 [kW]Method source ↗
