COOL
Cooling and humidity control
In hot climates the cooling system is the project. Evaporative, mechanical or hybrid — each fits a different humidity regime.
Pad and fan cooling works by evaporating water into the incoming air: excellent in dry heat, weak when the outside air is already humid. Mechanical cooling with dehumidification holds temperature in humid heat but costs electricity.
The right answer is usually a hybrid switched by season, sized on the design day rather than the annual average.
Specification
| Evaporative | Cellulose pad walls with exhaust or distribution fans |
| Mechanical | Chillers, coils, reheating for humidity control |
| Hybrid | Both, season-switched |
| Control | VPD-based strategy, not temperature alone |
Options and sizes are fixed against the house geometry and the site's design conditions.
