Summary

In comparison to standard thermostatic expansion valves, new electronic expansion valves offer much better conditions for adapting the evaporator mode to operational demands. The capability of registration and statistical evaluation of evaporation and ambient conditions by microprocessor control makes it possible to reduce refrigerant superheating and to lift the evaporation temperature. That means an improved COP and a reduction of defrosting mode. The energy behaviour of the electronic expansion valve was compared to that of the thermostatic valve through an exergy analysis.
