thanks for the explanation, The hole idea was to override the solar collector with that copper tube.
Yesterday i received my bottle of nitrogen. And today I made my first braze on two spices of pipe. My first reaction was it looks good!
I used 5% silver solder.
Bottle of nitrogen and my small solder kit
Two pipes i want to braze together.
Right after brazing.
Picture of the inside, I think it looks quite nice.
I also bend the pipes between the unit and the heatexchanger.
Is this the way it should be connected?
The outdoor unit has no electroics inside at all. The inside unit was designed to control the outside unit simply by supplying the compressor fan and valve.
On my dally bases i am an electrician, i love to build electronics and program stuff so i want to build my one controls, the same as i did with my wood stove.
What i understood that it is possible once the gas in released in the heat exhanger. That i can suck the refrigerant back in the outside unit if I want to change some thing on the heat exchanger. Eventually I want the heat exchanger inside the house and i have to remake the connections between them.
