Morphing Air Conditioner into Autocascade System

i think i'm a bit tired so here i go mumbling: what is: '' sub = 30" x .026 '' ?

It is used in conjunction with what Cryo-Tek and myself call the "sub-cooler", or perhaps better described as: the "R14 sub-cooler" which is its real purpose. This has been discussed many times before, but for a quick re-cap on the theory: The sub-cooler is intended to sub-cool the R14 liquid which passes through it, down to a temperature that some of the Argon gas is able to go into solution with the R14, thereby creating a lower boiling point condensate for later evaporation. Being isolated from the evaporator return flow, allows it to run at lower temperature then Cascade #3 that proceeds it.

edit: The sub-cooler isn't absolutely necessary for making an R-14/Argon blend work. If the load is kept relatively light, Argon can still be used. However under higher loads, the sub-cooler becomes much more important when Argon is to be used as part of the charge.

I have created a diagram which outlines the 1HP system Cryo-Tek was talking about. I have also taken the liberty of adding in the Hot-Gas defrost circuit that he briefly talked about in one of his later posts.
