Yep
It's only particularly relevant to higher loads. Maybe I should be a bit more detailed about that, and why I use it, why i post it.
When loads were 200w or less, this mod was pointless. No worth the effort the the gains provided. 1 or 2 degrees at best and that's hard to test and confirm.
When loads started to reach 300 and up, I started playing with tuning methods. SLHX setups, suction volume, evap setups, etc.
Getting a system that at least got the condensor capacity for the higher load is always a requirement. But in those, if you add more gas you end up with floodback grief.
So you add more suction volume, larger accumulators, larger larger less compact and it's a pain.
So a more elegant approach became necessary (to me at least) to get past that. My intention wasn't better temps, it was dealing with load in a more compact fashion. The initial idea, you get the captube colder, the return pipe warmer. Vaporisation's better, floodback reaction reduced.
And that's a part of it, but it became a lot more when I played with it.
Subcooling the captube made it need less gas. I've kept track of the usual amounts in the different systems, and I noticed that was a trend with the mod. Same capacity, less gas to have it.
At higher load testing, high pressure was lower. So I start thinking about the why, and can only assume that it's the captube that's the key. Raise the level of subcooling, increase the liquid to gas ratio IN the captube, there's less gas in the rest of the system, pressure's lower. (it's not that simple, but along the lines of where I've gone in theory)
Lower pressure to condense means lower pressure to evaporate at that high load. Compressors operate with a high and low pressure that are connected to each other, based on the power of a the compressor.
Slightly lower power consumption, since the less work the compressor does (with lower pressure to condense) with less strain, the less power it needs to do it's work.
I came up with the setup for the ease of high load tuning. The improvements were more or less a lucky byproduct that I found and started playing with, trying to get the best location, best captube sizing to work with it, etc etc and this is as good as it is so far.
But that's about it, and I'm kinda 'done' with this mod. If you have a question you're welcome to PM me about it, but the thread's been nothing but grief since day 1, with only a couple of bright spots. I wanted to help out, not start an argument, and that's all I've much seen from it.
So if you like it, use it (or any variation you like of it) and if you think it doesn't work, don't use it.
But I can't really make myself care much about it anymore. Nothing personal, when your dog bites you every time you give him a bone, you stop giving out the bones.
It sounds like there's someone interested in doing some further research and testing on it, and if they do and post and all that, they can take over. When that happens the questions can go there instead.
