Heat exchanger. Crimping.

Read the Transcript

• Greetings, boys and girls!
• Welcome to the next series of my story.
• I’m doing crimping for my evaporator
• Here is the diluted soapy water.
• I’ve pumped up the system through this valve
• And now I’m looking for holes.
• Already found one. Fixed it too.
• This is my instrument
• I made this nozzle
• The pressure gauge
• With it, I can monitor the pressure in the system
• Then I cut in half the filling hose
• Because it’s hard to find these things for sale separately
• Of course, the ideal would be to press on this thing here and make some sort of adapter
• Which means that I’d have to buy it somewhere
• I couldn’t find it nearby
• So, here’s how the crimping process goes
• I’m not sure, should it be a separate series or be included in the next one
• We’ll see
• Ok, I’ve crimped the heat exchanger
• The evaporator in which freon will boil and transfer heat into the house
• Turns out there was only four or five holes
• With so many connections … I’m pretty surprised
• Because I don’t have a lot of experience in soldering,
• or the practice
• But I have a good instruments, I guess
• And some portion of luck
• I cleaned it up a bit
• After soldering it looks like it has fat all over it
• When I was washing it up
• all the fat washed off with the soapy water
• I washed it with a cleaner for bathtubs
• The next stage - I’m gonna have to connect a geocontour
• And then the freon
• If something goes wrong with the geocontour, to not let out the freon
• I decided to put it in a barrel for reliability
• Now, the freon contour is pumped up to 6 atm
• The compressor can’t give more
• I don’t see any bubbles so far
• Washing with the soapy water doesn’t give such a good result,
• as if you just put it
• in a barrel with water.
• In that way, we’d definitely see some bubbles
• But it seems like everything is ok!
• Alright, see you in the next series, Cheers!
