This webinar, presented by Danfoss Application Engineer Jeff Staub, will help field service technicians gain a better comprehension of the function and operation of, as well as key troubleshooting strategies for, stepper motor and pulse-width-modulating electronic expansion valves. Participants will learn how adaptive control achieves optimal minimal superheat and what the difference is between a mechanical and electronic expansion valve in superheat control and capacity selection.
After viewing this webinar, you will be able to:
-
Define how expansion valves function in a refrigeration cycle, including how mechanical expansion valves differ from electronic expansion valves.
-
Determine methods for correcting superheat to achieve optimum evaporator efficiency.
-
Select the proper expansion valve based on the application and system conditions.
-
Differentiate various superheat controllers, and be able to define an appropriate system configuration based on application parameters and required control modes.
