How to use water cooling coils diagrams:

Air Speed. Starting from 4000 m3/h on the air flow scale draw a vertical line 1 till the air speed axis. It makes 4.15 m/s.

  • Supply air temperature. Prolong the line 1 up to the point where it crosses the outside air temperature (e.g. +32°C); then draw a horizontal line 2 from this point to the left till  crossing  the outside air humidity (e.g. 50%). From this point draw a vertical line 3 to the supply air temperature at cooler outlet axis on top of the graphic (+19.8°C).
  • Cooling capacity. Prolong the line 1 up to the point where it crosses the outside air temperature (e.g. +32°C) and draw a horizontal line 4 from this point to the right until it crosses the outside air humidity curve (e.g., 50%), from here draw a vertical line 5 up to the scale representing the cooling capacity (28.5 kW).
  • Water flow. Prolong the line 5 down to water flow  axis at the bottom of the graphic 6 (1.14 l/s).
  • Water pressure drop. Draw the line 7 from the point where the line 6 crosses the black curve to the pressure drop axis. (28.0 kPa).
