I am trying to operate the compressor of a refrigerator using my hand. I have opened the case of the refrigerator compressor and removed the part responsible for the compression. I have made a gearbox and connected it to the rotor of the compressor as shown in the figure below.
I have connected the condenser, dryer, capillary tube and evaporator using copper tubes in the mentioned order.
I am able to see two tubes(marked by green and orange circle) coming out of the compressor as shown in the figure but not able to understand on which tube of the compressor I should connect the high-pressure vapour part and which tube to the low-pressure vapour part.
I also want to know how to fill the tube with the refrigerant so that upon rotating the crankshaft I could obtain the refrigeration cycle.
Please help me with my project and correct me if I am doing something wrong.
