Abstract
To evaluate the issue of optimum control in hydronic radiant floor-heating systems, a comparative study of proportional flux-modulation and various types of temperature-modulation approaches was conducted in a laboratory setting during the 1990-91 heating season. The results showed that proportional flux-modulation favorably compares with temperature-modulation approaches by maintaining a stable indoor temperature around the setpoint and by demonstrating immediate response to any internal load disturbance. Temperature-modulation approaches, on the other hand, showed sensitivity to the reset ratio and boiler water temperature. Indoor temperature feedback was therefore recommended to help compensate for these potential errors.
