Hallowen and I go back about 10 years ago from Team Puss forums. He asked me to do this single stage for him not because he doesn't know how, but he's just not set up to do it himself at the present time.
This will be a simple walk-through of the procedure and parts I use to build my single stages. This unit will be built to handle 300watts of heat at approximately -35C using refrigerant r507. There will be lots of pictures. I hope no one minds.
I use a 3/4 hp condenser to dissipate the heat.
Along with that I use a matching 3/4 ton Danfoss 18CC compressor.
Compressor is mounted to base and discharge and liquid lines are run first.
I like to paint all copper joints to keep them from oxidizing and for general overall looks.
While the paint is drying I work on the wiring.
Simple ON/OFF switch
Evaporator starts out smooth and clean on the inside but I like to rough it up a little to add more turbulence to refrigerant to aid in evaporating.
Evaporator is then cleaned and brazed.
Next up is assembly of line set.
Finished brazing and clean.
I like to pressure test line set to 250psi and dunk it in water to be sure I have no leaks.
Cap tube is added and line set is wrapped with water proof mastic tape to hold the cap tube tightly to the suction line.
Okay line set is all together and ready to be installed on compressor.
More pictures coming after leak testing is finished. Thanks for looking.
