Heating capacity

The principle of heating capacity

Heating performance

Depending on the mixing factor (m), from the outlet onwards, the discharged air quantity (V0) – with an output temperature of e.g. + 34 °C (tA) – induces the ambient air on both sides of the stream. Here, in the region of the door, that comprises external and indoor air components.

Due to this physical characteristic, the initial air quantity grows into an overall air mass moving in the stream. During this process, both the initial speed of the air stream and the initial temperature drop.

The output parameters of our door air curtain units are calculated so that there is still a residual speed of approx. 1 m/s or more after the desired stream length, as well as a room temperature of about + 20°C. This is the only way to ensure effective function.
