- 20. Ambient T Defrost T Compressor duty cycle on time with TEV Compressor duty cycle on time with EEV LOWER!! Thanks to ExV, compressor duty cycle “on” time is lower this means an effective energy saving for the system Compressor duty cycle with TEV Compressor duty cycle with EEV Performance EEV vs TEV
- 21. STEPPER valves continuously and instantly modulate refrigerant flow at all times (as simple as that). PWM valves obtain a variation of refrigerant flow as an “average” over a consistent time window. When measuring instant refrigerant flow, it is either 100% or 0%. Stepper & PWM: refrigerant flow Description and principles What about EEV vs PWM performance?
