Abstract(s)
This paper presents the development of an innovative control, regulation and command
system for hydronic radiant floors, more flexible and efficient that guarantees a better thermal
comfort to the user and simultaneously improves the energy efficiency of this type of heating
system. The majority of the actual control of hydronic radiant floors is done by thermostats that
measure the air temperature and control the actuators (pumps and valves) in order to maintain the
room at the specified temperature. These systems requires the frequent adjustment of thermostats
set-point in order to obtain thermal comfort as it depends on other factors than just the air
temperature, such as, the air humidity, external environmental conditions, radiant temperature,
among others. This paper presents a control, regulation and command solution that requires
minimum user intervention, as the user only has to choose the desirable thermal comfort level. The
control algorithm is based on the calculation of PMV (Predicted Mean Vote) index as defined on
Thermal Comfort Standard ISO 7730. Another advantage of the proposed system is related to the
wireless and energy harvesting sensors and actuators that provide much more flexibility to the
system.
