Determining heat consumption of domestic radiator - processing measured temperatures only when regulator valve is open and surface temperature distribution is uniform

摘要

The forward and return flow temps. and that of the room to be heated by the radiator (32) are measured by sensors (33-35) and combined with heating constants specific to the equipment properties and prescribed standards. A computer (36) generates an output signal corresp. to the quantity of heat required, for use in operation of a pref. thermoelectrically controlled valve (6) which includes an element which can be electrically heated for closing the valve. USE/ADVANTAGE - In a regulated central heating system for calculating heating costs for individual users. The heat consumption can be determined with higher precision without additional cost in equipment and computer power.
