Subcooling Effect With Non Condesable Gases

[MayankBhatia]

Hi friends

Today i Found That system Contains Some Non condesable gases.So i want to know How it make the liquid line exceesive subcooled.As Condensor fan efficiency is fixed if it can Coo down Some amount of gas them if Non cond. Gases take some place then its efficeincy should be decreased and Liquid line should be hot than cool?Anyone can explain where ia m lacking
?

with non condensables your pressure increases greatly

giving the false impression of high subcooled refrigerant

you can not correctly ascertain the refrigerants condition when non condensables are present

Generally, non condensables gases in a refrigeration system will collect in the top of the condenser, reducing the capacity of the condenser, this increases condensing temperature/pressure. Under these conditions you certainly won't find excessive sub cooling, unless you have very cold ambient temperatures

i was reading on this page http://www.achrnews.com/articles/120122-what-to-do-if-you-have-a-noncondensable-gas-in-your-condenser

they had explain some concept using Q=u*a* delta T.So anybody can have light on this in detail?
