HVACR: Water Source Walk In Refrigerator Not Cooling/High Head Pressure (Troubleshooting & Repair)

[@topher8634]

I recommend oxyacetylene for brazing on refrigeration equipment. B torch takes longer to heat and you run the risk of overheating other components. Oxyacetylene heats quickly, allowing you to flow the alloy and pull the flame off sooner.

there's a time and a place for both setups, keep both around

Also there are rules for NYC travel and what buildings allow.

[@topher8634]

You can use oxyacetylene in NYC. Hospitals won't let you bring torches in without extensive approval. B torch (straight acetylene) is great for plumbing and anything soft soldered. Didn't say ditch it, just don't recommend for silver soldering, the melting point is near that of the copper. B torch takes a while to get there and the whole time you're heating, the heat is traveling to other components that can be damaged by excessive heat (e.g. valves, sight glasses, driers) even if you've taken pains to prevent it with wet rags and heat blocking putty.

Great job as always brother. Another one in the can. As us older time video guys say

[@zekenzy6486]

1:41 Oh dear what ref engineer left that there for the next person😢

[@ChrisWright7701]

Did you replace the time clock.

Why not use adapter unions?

[@sherwinalvarez7365]

High back pressure. It may need a TXV adjustment to see if its bad.

[@peteaceves5237]

1/2 to 3/8 may not be a big gap but its best to go with what the manufacturer asks for. It would suck to install it and have it not work due to a restriction.

[@wrestlingterrier8366]

Is 1/2 to 3/8 considered a restriction?

[@peteaceves5237]

@wrestlingterrier8366 Depending on the equipment it can be.

[@wrestlingterrier8366]

@@peteaceves5237 I see. Thanks !

[@joshstevens9826]

Water valve is on the wrong side. Should be on the leaving side, not entering water

[@dylanengholm5051]

I recommend removing used filter driers with cutters instead of brazing since the heat will expand the moisture and other build up into the system quicker than you can take it off
