Water heater parameters:
Water heater parameters calculation example:
Air Speed. Starting from 3500 m^{3}/h on the air flow scale draw a vertical line ^{1} till the air speed axis which makes 4.65 m/s..
- Supply air temperature. Prolong the line ^{1} of air flow up to the point where it crosses the outside air temperature (-10°C); then draw a horizontal line ^{2} from this point to the left till crossing water in/out temperature curve (90/70). From this point draw a vertical line ^{3} to the supply air temperature axis on top of the graphic (+22.5 °C).
- Heating capacity. Prolong the line ^{1 }up to the point where it crosses the outside air temperature (red line, -10°C) and draw a horizontal line^{ 4} from this point to the right until it crosses water in/out temperature curve (90/70), from here draw a vertical line ^{5} up to the scale representing the heating coil capacity (42.0 kW).
- Water flow. Prolong the line down to water flow axis at the bottom of the graphic ^{6} (0.5 l/s).
- Water pressure drop. Draw the line ^{7} from the point where line ^{6} crosses the black curve to the pressure drop axis. (6.5 kPa).
Water cooler parameters:
Water cooler parameters calculation example:
Air Speed. Starting from 2850 m^{3}/h on the air flow scale draw a vertical line ^{1} till the air speed axis which makes 3.85 m/s.
- Supply air temperature. Prolong the line ^{1} of air flow up to the point where it crosses the outside summer air temperature (+32°C); then draw a horizontal line ^{2} from this point to the left till crossing intake air humidity curve (50%). From this point draw a vertical line ^{3} to the air temperature downstream of the cooler axis on top of the graphic (+20.7 °C).
- Cooling capacity. Prolong the line ^{1} up to the point where it crosses the summer outside air temperature (+32°C) and draw a horizontal line ^{4} from this point to the right till crossing intake air humidity curve (50%), from here draw a vertical line ^{5 }up to the scale representing the cooling coil capacity (19.8 kW).
- Water flow. Prolong the perpendicular line down to water flow axis at the bottom of the graphic ^{6} (0.78 l/s).
- Water pressure drop. Draw the line ^{7} rightwards from the point where the line ^{6} crosses the curve to the pressure drop axis. (30 kPa).

- Coolant flow. Prolong the perpendicular line down to coolant flow axis at the bottom of the graphic ^{6} (310 kg/hr).
- Coolant pressure drop. Draw the perpendicular line ^{7} rightwards from the point where the line ^{6} crosses the curve to the pressure drop axis. (24.0 kPa).
