Looking at the ON phases and focusing on steady-state
condition (approximately after 10 min), in the low-pressure zone
of the plant one can observe slight deviations for the temperatures
recorded for both refrigerants; in any case, the differences are
contained within a narrow range equal to 1.5 C. Contrary,
HFO1234yf has caused an increase in the temperature levels in the
high-pressure zone of the plant.
