The engine temperature of the ammonia engine is too high – how to fix it?
Thread Content
The oil cooler of the ammonia unit in this facility uses liquid ammonia from the siphon tank for cooling. A month ago, air entered the ammonia system because the filter at the inlet of the ammonia unit needed to be cleaned. I would like to ask everyone: after the air in the ammonia system exits the evaporation condenser, does it enter the siphon tank, or does it accumulate at the top of the pipeline at the exit of the evaporation condenser? If air enters the siphon tank, will it affect the cooling efficiency of the oil cooler? Currently, none of the 3 chillers in the facility can operate at full capacity. When they were operating at full capacity before, the oil temperature during summer would never exceed 51°C! It can now only operate at 60% load!
In the cycle of condensation and evaporation, if air enters, it occupies the heat exchange space in the condenser, resulting in a decrease in the efficiency of natural cooling. It is recommended to handle it thoroughly.
Some non-condensable gas can be vented from the condenser at the upper end, or. Find a way to remove the vacuum
