Flooded evaporators
Hi all
Im new to this forum, ya just have to thank Mr Gates for starting all this. Its awsome.
I have an R-22 system with flooded evaps running 45 degress. Would like to know if any what are my options for automatic oil return. Currently have a drain off the bottom that drains back to a low side oil resovoir with a hand valve and solinoid valve. The valve just closes for pump down. Also read with R-22 the best place is not the bottom of the evap but off the top. Also thinking of changing the system to 134 with POE oil. Holds about 600 lbs. Thanks
