Summary

The paper reports on the difference in performance between the electronic expansion valve (EEV) and the conventional thermostatic valve (TEV) when used for evaporation in a cold store. The experiment consisted of a comparison test with mechanical refrigeration using an ammonia vapour compression cycle. The result of the experiment showed that the EEV can cool down cold stores in 76% less time than the TEV. Energy consumption used to keep the refrigeration runing at -24 deg C decreased by approximately 30% when using the EEV, compared to the TEV. The authors estimate that the initial cost may be recovered in less than two years.
