With the table below, you can easily make a calculation for heating a standard production hall.
Starting points and points for attention:
- Daylight in wall and/or roof approx. 15%. Floor construction concrete on sand.
- Take into account extraction systems, scaffolding and crane gantries.
- Consider the number and position of service doors.
- Note any heat gains from machinery and lighting.
- All capacities (in kW) apply at an indoor temperature of 15°C and an outdoor temperature of -10°C.
- For each degree Celsius more or less, the output must be corrected by 4.0%.
Volume: 5,000 m³
Height: 6 meters
Insulation value: Rc = 2.5
Desired indoor temperature: 17°C
- The heating capacity table shows under Rc = 2.5 and a capacity 5,000 m³ 80 kW (at 15°C).
- To achieve a room temperature of 17°C, the required capacity is: 80 kW + (2 × 4.0%) = 86.5 kW.
- Read off the required circulation volume: minimum 15,000 m/h.
- Depending on the layout of the hall, divide the power between 1 or more air heaters. This gives better heat distribution.
