Core Refrigeration: Refrigeration Wiring

[@rahmanyalshugaa3556]

Really I will thank you again and again because I found what I'm looking for, I hope to get more information about mid -temprature and low temprature

Let me see what I can do on the refrigeration side. I am pretty busy with air conditioning right now, but I have a few things in mind on the refrigeration.

[@brianpan57]

this was amazing valuable information. especially for a starting refer tech. today i came across an old r12 cooler with a lpc used as a thermostat. and the unit was freezing all the beverages. i tapped the lpc and the unit shut off. can you show me the wiring diagram of a lpc as a tstat? there wouldn't be a llsv right? because there isnt anything that will energize the llsv

[@cmolnar65]

Correct on the no LLS. Take L1 to the pressure switch out of pressure switch to condenser (compressor/compressor fan). Make sure you put any high pressure switches in series with that. L1 gets wired directly to evap fan (do not go through pressure switch). If evap fan does not run constantly this will not work properly. If no evap fans allow a little more of a differential between cut in and cut out. Does that help?

[@brianpan57]

So what allows the psi to go up and down? With it being off?

[@brianpan57]

This unit didn’t have an evap fan. Just coil. The cut in was like 35 and differential was 15

[@cmolnar65]

@@brianpan57 when the compressor shuts off, the refrigerant pressures are determined by the temperature of the air surrounding the coil. Temp/pressure relationship. You just have to know the appropriate pressures. I will try to do a video on this Friday or Sat when I have some time.

You are so good, you should have million of viewers

[@rahmanyalshugaa3556]

Thank you so much is very helpful, and I hope to get more information about the wiring in the condeser and inside the box

[@TheJoypool]

Interested in wire type inside fridge for fan and all internal too

[@BLK-ICE]

great video very help to someone like me that is still in school

[@TheJoypool]

If I need to rewire all the internals what kind of wire or insulation and specs should I go for
