Latest / The Refrigeration Mentor Podcast / Episode 403. CO2 Liquid Line Piping
Transcript
- 0:00Speaker 3: My name is Trevor Matthews, founder of RefrigerationMentor.com. Over the past decade, I've trained tens of thousands of refrigeration technicians and contractors on supermarket refrigeration, and I've seen the same problem across the industry. Technicians are under pressure, second-guessing, and getting stuck on jobs too long.
- 0:03So basically, what does that mean? I have a liquid line going out, leaving my receiver or my flash tank, and that supplies both the medium and the low temp cabinet. So as it travels out, you're taking feeds off for circuit one, circuit two, circuit three, circuit four, circuit five, circuit six, but then that suction comes back and picks up circuit one, circuit two, circuit three, circuit four, circuit five, circuit six.
- 0:06And so in Fahrenheit, you're running it maybe from 28, which is on the cold end, up to 40, 42, depending on where that lands in the, the pressure range. And then now if you talk about a higher pressure system, it's 90 bar, you can run a lot warmer liquid out to those, out to those cases. Okay, so what does that really mean?
- 0:09So this is why you ask them the questions, "Why are we doing this?" And this should, the, you as a technician should talk to your foreman about it, and your foreman should talk to the project manager, and that project manager should be talking to the manufacturer about it. Okay? 'Cause they're not the only manufacturer that do it.
- 0:12I, I'm working on CO2, but I've not spent enough time being trained on it, mentored and coached on it, on these different systems," because it doesn't really matter to the systems. We're system agnostic. We just really wanna help you succeed if you're working on any rack manufacturer, any rack controller, any component.
