Non-Condensables In Refrigeration System

  1. Feb 16, 2012 #1
    Got a debate going on with some HVAC supertechs...One contends a sufficient quantity of non-condensables in a refrigeration system (vapor compression & med/hi temp application) will circulate "around" the system. He's saying with the "sufficient quantity", the liquid seal will be lost at the condenser outlet. He's also qualified the operating conditions of the system as having high subcooling, which I'll translate as more than 10°.

    So, if you start out with a system that would normally run 10° subcooling, then add some non-condensables (sufficient or otherwise), that eventually find their way to the condenser, how can they exit the condenser or affect the "liquid seal" created by the excess refrigerant, that provides the liquid seal in the first place? And assume the refrigerant hasn't reached "critical point" which I believe is a safe assumption for a beer cooler or residential A/C. :biggrin:

    Thanks in advance for your time and thoughts. :smile:
