| Abstract: | This paper describes the basic requirements for flow control of the thermal performance testing system of solar collector,then gives a control measure of the small flow in a closed loop control system,solves the bubble problem when the flow medium temperature rises significantly,proposes a way to measure the flow accurately.Practice shows that this flow control system has fast response,small overshoot,and high steady-state accuracy. |
