Energy-Saving Design for Pressure Difference Control in Variable Flow Air Conditioning Systems

This paper analyzes energy-saving design for pressure-difference control in a variable flow air conditioning system, including the application of a pressure-difference control valve and the installation position of a pressure-difference transducer. The conclusion is that installing a pressure-difference control valve can increase hydraulic stability, and reduce pump head and pump energy consumption. The application of terminal control has the smallest energy consumption, but flow variation scope is narrower than everything else
