DIFFERENTIAL PRESSURE SENSING SYSTEM, PIPE UNIT, USE OF A PIPE UNIT, HEAT DISTRIBUTION SYSTEM, USE OF A HEAT DISTRIBUTION SYSTEM AND METHODS

摘要

The invention relates to a differential pressure sensing system for sensing a differential pressure in a main flow duct, more particularly a differential pressure in a pipe system of a heat distribution system for a building, the differential pressure being sensed with the aid of a temperature fluctuation at a temperature sensor, to a pipe unit for a differential pressure sensing system of this type and to the use of a pipe unit in a differential pressure sensing system of this type. The invention also relates to a heat distribution system and to diverse uses and methods for a heat distribution system. In contrast to prior art, the differential pressure is not sensed using a piezoelectric pressure sensing system, but in a space-saving manner by measuring a temperature using a cost-effective, robust temperature sensor, thus dispensing with the need for a plurality of components for a heat distribution system.
