Matching controlled rotary pump system hydraulic power characteristic to heating system requirements - involves selecting value corresp. to flatter pipe network system characteristic determined by comparison, with power characteristic limited depending on last stored value

摘要

The method involves determining the heating system's operating point (P1) whilst operating the pump system and storing at least one value characteristic of the pipe network properties. A second step involves determining the operating point (P1) again after a time period and comparing the associated characteristic value with the stored value. A third step involves storing the value corresp. to the flatter of the pipe network system characteristics. The second and third steps are repeated and the power characteristic is limited depending on at least the last stored value to match the pump system to the heating system.
