Morphing Air Conditioner into Autocascade System

[mytekcontrols]

When I said HZ box before I meant HX box (Typo) - The internal flares coming out from where the HX stack is.

Yep did that for several reasons. ease of maintenance, maintain good seal for keeping water out of insulation foam, and able to eventually create modular drop-in replacement HXC stack.

I'm slightly concerned about how the little blue condenser will hold up but I don't even know how much heat you are dumping, so besides pump-down it should be sufficient given a sufficiently small load.

What kind a fan are you using with this condenser ?

Yes my load will be small, probably 15-25 watts. So a large condenser shouldn't be necessary. Also keep in mind that because of my "Regenerative HXC" on the compressor discharge (for creating the hot gas defrost from the colder 1st phase sep gases), I have effectively extended the length of the air cooled condenser.

As for fans; I am using the stock fan that comes with the Little Blue condenser, but I also intend to supplement this with an additional 120CFM fan directly behind the compressor (will be mounted to outside of the future rear panel).

I eagerly await your analysis of the unit once it is operational, especially if you can at least share a little information on the gas blend you'll be utilizing.

Chris - I'll be using R600,R170,R14,Argon in this puppy, but unfortunately can not disclose the exact amounts of each (this unit is aimed at becoming a commercial product).
