Expanding psychrometrics to enable humidity management through warm radiant comfort delivery

Air conditioning enabled the direct control of temperature and humidity. The resulting prevalence of all air systems resulted in a focus on the psychrometric chart. This caused the control and definition of thermal comfort to orient around the mechanical management of these two variables. We are interested in the manipulation of other thermal comfort variables to affect comfort. We present the ability of radiant heating to enable lower air temperatures while maintaining the same indoor comfort, and thereby resulting in a psychrometric increase in humidity, thereby mitigating a common challenge of low winter indoor humidity. This is achieved without active humidification systems that cause other indirect problems.
