Electronic Expansion Valves Electronic Expansion Valves Fitters Notes ( Part 8 )

Stephan Bachmann, Danfoss Refrigeration & Air Conditioning, Offenbach Lately we have received a lot of customer questions about using electronic expansion valves, so the eighth instalment of Fitters Notes is entirely dedicated to this topic. Optimal evaporator filling (even with large load variations), flexible MOP points, and using the highest possible evaporating temperature in order to increase energy efficiency are topics that always interest refrigeration system engineers and operators. In many cases, theses requirements cannot be fulfilled adequately with standard thermostatic expansion valves. Electronic expansion valves, by contrast, are very well suited to the task.
