| To obtain generally applicable values for the flow of cooling air  C the following outline conditions have been set that influ-ence the volume of cooling air  C .
- Room temperature 35°C = 308 K
- Temperature gradient Dt 10 K
- Wall thickness 25 cm
The surrounding walls are assumed to be homogenous
brick walls without windows and doors.
- Room height and size.
The room height is defined as being lower than 3 m and the area of the room less than 50 m².
The defined outline conditions above assume the least favourable admissible environment for operating the compressor. The values calculated for the flow of cooling air  C are generally applicable because conditions in real installation rooms are normally better.
Thermal problems will not occur if the recommended flow of cooling air  C for a compressor is assured. |
