This is what i want to do.

Well i have recieved a fridge on R134a ,Fan forced evap
induced fan condenser. It is a commercial shop fridge.

It is a project at home, i want to fit schraders and service valves to the system to read pressures at different points at different loads.(yes i am in the trade)

Any thoughts where you would put them ?

I'm thinking on the same lines as you have 4 or 5
different systems in the 1 !

Tx, cap tube, float type controls.
the later being hard as it has no bore but maybe, used in conjunction with a reciever it might work.

A control to isolate different parts of the system (eg)(compressor,fans,flow controls,lights,relays)

Also maybe a series of sight glasses in the evap and condenser to show the flashing off of the refrigerant.


ANY IDEAS ?
