| Abstract: | In order to deal with the shortcomings of the capacity detection device for thermal expan-sion valve, such as low automatic level and poor test accuracy, a capacity test system for thermal expan-sion valve is designed according to the test method which is provided by the national standard QC/T 663-2000. On the hardware design, the system consists of opening test device, refrigerant flow test device and control module. On the software design, this paper use Visual Basic 6. 0 developed a set of visual test software. The experimental results of capacity test showed that the system could well realize the ca-pacity test of the thermal expansion valve, and its test accuracy had reached 1. 0%. |
