4172 — Zero-Load Control of Indoor Thermal Environment

Click here to purchase
The primary objective of HVAC systems is to make human occupants thermally comfortable. In practice, many systems fail to achieve this goal for a variety of reasons. Two important reasons are: improper system control objective and incapacity to deal with a nonuniform thermal environment. In this study, a new control objective is proposed based on the physiological load on the human thermoregulatory system. A closed-loop control algorithm is then developed using real-time human physiological signals. Experimental results on a thermal mannequin have shown that such a control algorithm is a better way to regulate the local thermal environment than traditional control algorithms. Instrumentation issues also are addressed in the paper.
