Climate Control Load at 11% duty-cycle and door-opening allowance: a worked example

Suppose duty-cycle and door-opening allowance falls to 11%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate daily HVAC and dehumidifier runtime needed to remove the transpiration moisture and sensible heat load from a greenhouse or indoor grow room based on the daily moisture load, equipment removal capacity, and a duty-cycle allowance for door openings, lighting transitions, and outdoor swings.

The inputs for this scenario

  • Daily moisture load to remove: 720 pints / day (held at the documented default)
  • Installed dehumidification removal capacity: 60 pints / hour (held at the documented default)
  • Duty-cycle and door-opening allowance: 11 % (the input this scenario stresses; the baseline uses 15)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base dehumidifier runtime = daily moisture load to remove รท installed dehumidification removal capacity.
  • Required daily climate-control runtime works out to 13.32 hr at these inputs, and this is the headline figure for the scenario.
  • Base dehumidifier runtime works out to 12 hr at these inputs.
  • Duty-cycle and door-opening allowance works out to 11 % at these inputs.
  • Installed dehumidification removal capacity works out to 60 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where duty-cycle and door-opening allowance sits at 15% and the headline result is 13.8 hr, this scenario comes in 3.48% below the baseline at 13.32 hr.
  • It computes required daily climate-control runtime by dividing daily moisture load by installed removal capacity, then padding it with a duty-cycle and door-opening allowance. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Required daily climate-control runtime: 13.32 hr (headline result)
  • Base dehumidifier runtime: 12 hr
  • Duty-cycle and door-opening allowance: 11 %
  • Installed dehumidification removal capacity: 60 pieces / min
