Trying to understand how AC freezer works...?

Question

I have a good understanding for how A/C systems work, but I have a typical (7 cu) small freezer that I am repairing a leak on, that I do not appear to understand how it works. I am an amatuer and not a professional, but I am an electrical engineer so I guess you could say I am not a complete idiot.... :)

On the high (condensor) side, one end goes out of the compressor to the condensor coil located on the back of the freezer. The the other side of the condensor coil, however, goes back to what I think is the dryer, but the other side of the dryer is pinched off and dead ends. Meaning, it does not appear that the loop of the condensor coil goes back to the compressor... It appears rather odd...

On the low (evaporator) side, I can see where it comes out of the compressor, but it does not appear to come back.... Meaning, it leaves, and does not appear to link to any expansion valve / Dryer I am aware of...

Am I missing something, or is this A/C freezer seem to work

Answer 1

The pinched pipes are the fill points. It's got to have an exit and return. Just don't forget thaqt it might be possible to telescope the plumbing if they can save money that way.

This website describes basic operation and plumbing schematic...

Answer 2

when the compressor is pumping, its pumping a liquid, when it goes into the evaperator coil, it turns to a gas, when it asorbs heat, and is forced back to the compressor thru the condensor coil, as more liquid is pumped to the cooling coil, the vapor as it loses its heat [condensor coil] it turns back to a liquid,
mine works like that, its a one line from the compressor to the coil,
