Known psychometric characteristics of air are employed to achieve accurate indoor relative humidity control to prevent condensation inside a building envelope without complex mathematical computational requirements. An HVAC system control includes a simple control algorithm employed to calculate an effective delta (DeltaT) based upon a single adjustment factor (A*) and environmental inputs. The effective delta (DeltaT) is then used to determine a maximum allowable indoor relative humidity. The system control is then operable to selectively activate/deactivate a device to adjust an actual indoor relative humidity to a value less than the maximum allowable indoor relative humidity to prevent condensation inside the building envelope. |
