An experiment instrument for the control algorithms of the electronic expansion valve（EEV） and its refrigeration system was given. The principle and the composition of experiment instrument were described. The design of hardware and software was introduced. Some usual control algorithms of EEV and its refrigeration system were experimented. The experimental results indicate that the experiment instrument can give the comparison of the EEV and its refrigeration system effectively.
