| Abstract: | This paper introduces the development of a test bench for measuring the flow characteristics of the throttle mechanism, its test principles of refrigerant flow, and one experiment on the bench by using short-tube orifices. The experiment results show that the test bench has great advantages on wide test range, better stability and higher precision,and it can also be used to study the flow characteristics of the throttle mechanism under different refrigerant parameters. |
