Air Speed. Starting from 3000 m³/h on the air flow scale draw a vertical line ➀ till the air speed axis which makes about 2.5 m/s.Supply air temperature. Prolong the line ➀ up to the point where it crosses the outside air temperature (blue curve), e.g. -15 °C; then draw a horizontal line ➁ from this point to the left till crossing water in/out temperature curve (70/50 °C). From this point draw a vertical line ➂ to the supply air temperature axis on top of the graphic (+35 °C). Heating coil capacity. Prolong the line ➀ up to the point where it crosses the outside air temperature -20 °C (red curve) and draw a horizontal line ➃ from this point to the right until it crosses water in/out temperature curve (80/60 °C), from here draw a vertical line ➄ up to the scale representing the heating coil capacity (65 kW).Water flow. Prolong the line ➄ down to water flow axis at the bottom of the graphic ➅ (4100 kg/h).Water pressure drop. Draw the line ➆ from the point where line ➅ crosses the black curve to the pressure drop axis. (45 kPa).
