Cold dryer in front of the nitrogen generator? Seeking advice
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 drop in temperature. What is the relationship between this and the evaporation pressure? Does low pressure facilitate evaporation? Curious about the structure of an evaporator?
A refrigerant is a cooling medium, such as R-22 in air conditioners
