This standard gives a method of testing for rating of duct-mounted air cooling coils, with chilled water as the cooling medium, within the following range of variables:

  • Inlet air temperature: below 40 °C
  • Inlet water temperature: 2 °C to 20 °C
  • Inlet air wet bulb depression: greater than 4 °C
  • Sensible heat ratio (Qs/QT): less than 0.8 (for dehumidifying coils)
  • Water flow: Reynolds number above 3 100
  • Air velocity at coil face: 1 m/s to 4 m/s

Duct-mounted cooling coil rating test with chilled water as the cooling medium within specified ranges of variables for inlet air and water temperatures and for water flow and air velocity.
