  • Page 128: Appendix A - Dehumidification Performance

    Lights themselves give off convection and radiant heat. The first impact this has is to raise the air temperature. As the immediate air temperature increases, the relative humidity resultantly decreases. Caron chambers provide stable and gentle forced air movement to maintain a uniform environment. The circulating air is also cooled to offset the affects of heat radiating from the lamps.
  • Page 129 Below is an example showing the temperature and humidity air measurements inside a Caron plant growth chamber. The first 8 hours are the day, then 8 to 16 hours is the night, and at 16 hours the transition turns back to day.
  • Page 130 Extreme Example A more extreme set of day/night conditions is shown in the illustration below: • Day: Temperature 25C, humidity 75%, 470 µmole/m /s of light • Night: Temperature 18C, humidity 75%, lights off The watering condition for this example is 7.6 ft of exposed saturated soil.
