Project Objective

The purpose of this research is to develop and demonstrate an integrated humidity and ventilation control solution to improve indoor air quality, comfort, and energy performance for low-load homes in hot-humid and mixed-humid climates. The solution strategy is based on a central air-conditioning system that is (1) specifically redesigned and optimized for "enhanced dehumidification" and (2) control-integrated and operation-coordinated with supply-type ventilation for prioritized ventilation.

Project Impact

The results of this project will simplify the transition to high-performance ventilation and humidity control systems. By relying on the central system as a starting point, the strategy will allow for optimization across all key metrics to the degree that is not possible with alternatives: eased transition across the entire value chain; reduced risk, cost to install, and cost to operate; effective humidity control and energy use, noise, and comfort. To enable standardization and broad industry impact, a secondary equipment rating based on latent load efficiency will be proposed.
