Hello everyone.
A open-type screw ethylene glycol unit.10℃ inlet 0℃ outlet.refrigerating capacity is 4300kW.I want to use flooded evaporator.but I am afraid the oil can't return.The compressor is open-type compressor.and the oil sparator is big enough.
which is better, flooded evaporator or thermosyphon evaporator.How to resolve the oil return? use auto-oil receiver or injector?
