Study on the Pressure Difference Control in Variable Flow Rate Central Heating Systems

Abstract:

Through analyzing the application of pressure difference control system in variable flow rate central heating system, the evaluation method based on maxim energy consumption calculation is presented. The constant and variable differential pressure control is separately studied, a conclusion is come to that the smaller the differential pressure controlled, the more energy saved, and the variable differential pressure control as far as possible to maintain the hydraulic resistance of system is more efficient.
