#2. Heat exchanger. Version 1.

Learn from mistakes. I suggest learning from mine :) An unsuccessful version of the heat exchanger between the geo-contour and freon.

• Greetings, boys and girls
• Today we’re going to talk about the second stage
• of my heat pump project
• I’ve made this pipe
• with the copper tubes inside
• you’ll see it later
• when we’re going to be welding
• the copper tubes
• These pipes are made of
• 2.5 meter pipe pieces
• each piece is a solid pipe 2.5 meters long
• Here’s my setup
• I’m using 5 pipes
• Later you’ll see how it goes
• I am not a professional welder, so please, don’t throw tomatoes at me
• It would’ve been unreal to weld with the ordinary welding spray
• I probably should add more oxygen
• Darnit, can’t warm this sucker up
• You can pause the movie for a sec
• So, what do we have: a pipe, 45 degree angle joint
• half-inch thread
• Allright. It’s ready.
• smooth on a paper but rocky on the road
• I ran out of oxygen on the first day
• I managed to solder 3 pipes
• Refueled the oxygen
• And started to solder the 4-th pipe
• And then I realized that I can’t solder it
• So, there’s really nothing substantial to show here
• All these pipes turned into a great radiator
• And I can’t heat up the soldering place
• And it’s only 4 pipes
• What’s going to happen when there will be 12 of them?
• So, I decided to use “Plan B”
• And that’s what my next video is going to be about
• What was my initial plan?
• I was planning that this radiator
• will go into this pipe
• We’ll solder it here
• with the silver copper soldering
• something like that…
• For the freon in and out
• middle pipes will be used
• And these are going to be for the soil heat exchangers
• So, in general
• anyway
• we’ll talk about the “Plan B”
• in the next video
• See you later, fellas!
