WebFloat type expansion valves are normally used with flooded evaporators in large capacity refrigeration systems. A float type valve opens or closes depending upon the liquid level … WebJan 22, 2024 · Thus, flooded evaporators can promote oil contamination of the evaporator charge because they may only return dry refrigerant vapour back to the system. If the temperature is very low, the oil becomes a gummy mass that prevents refrigerant controls from functioning, blocks flow passages, and fouls heat transfer surfaces.
