Seeking advice on issues with the cold dryer before the nitrogen generator? ?
Thread Content
Hi Haiyou, may I ask about the issues with the pre-cooler in the nitrogen generator? 1. What does condensation pressure refer to? 2. What does evaporation pressure refer to? 3. What does low refrigerant pressure and high refrigerant pressure refer to? Is it water? What I know is that there is circulating water. I looked up some information but didn’t understand it: the evaporator is used for heat exchange. How should this be understood? What is the principle of heat exchange? In compressed air, water vapor absorbs heat and turns into liquid water, causing a temperature drop. What is the relationship between this and the evaporation pressure? Does low pressure facilitate evaporation? Curious about the structure of an evaporator?
3. What does low refrigerant pressure and high refrigerant pressure refer to? Is it water? What I know is that there is circulating water; no, it’s the Freon or something similar that’s used in the compressors of cold dryers. This cold dryer works on a principle similar to that of refrigeration and air conditioning systems.
