Dear all,
This is an old question. BUt it is puzzling me now. I want to know the position of oil draining in the flooded evaporator.
R717 with mineral oil, the oil draining port set on the bottom; R22 with mineral oil , the ports set on the upper liquid level.'Cause the mineral oil and R22/R717 is immiscible.
But to R507 with miscible oil, R23 with miscible oil, where is the position to set in the flooded evaporater?I met this matter in the R507/R23 cascade system. High temperature stage condensing temp. is 40C, evaporate temp.is -25C. Low stage running condition is -20C(condensing)/-75C (evaporating).
kindly regards,
sagittarius
