Fitters Notes Series: Electronic Expansion Valves
28 August 2008
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.
Useful practical tips for the everyday work of fitters is provided in the “Fitters Notes” series. The “Fitters Notes” series is based on the handbook of the same name produced by Danfoss, which discusses the basic principles of commercial refrigeration systems and the associated basic components.
