CoolPack Video Tutorial (* Collecting Ideas *)

CoolPack Video Tutorial... sound too good to be true?

Well, for some reason, this well-respected, free, refrigeration design program has no video tutorial. At least none that I have been able to locate. I did find one with no audio, I suspect that the audio would be in French (nothing against French, mind you) so not so useful to me and many of you.

So, I think that the world could become a better place if there was such a tutorial.

So, I am collecting ideas as to what should such a tutorial should contain.

In other words, what would you like to be able to use CoolPack to help you with.

I think that if we put our heads together, we could come up with something quite useful.

Best,

-AC

As a proud Dane, I must tell you that any tutorial, not in English, would probably be in Danish.

Well, proud Dane, do you know of a video tutorial in Danish that could be translated into English by some interested proud Dane, such as yourself?

Only if the tutorial was made up of food words because my memory lacks for most of the other stuff.

I'm not sure cool pack is much use without a basic understanding of the vapor compression refrigeration cycle. First stop should be refrigeration 101 over at the refrigeration-engineer forums. Once you have a grasp of the variables, cool pack is pretty easy to get your head around.

It's based on a program called "engineering equation solver" where it tries to fill in the gas y ou leave when you fill in the other parameters, so you can fill in what you know and it will try and come up with probable results for the stuff you don't.

It would seem that the biggest problem with R290 (55C) is that its condensing temp is much lower than R410A (R71C) in a DX system running with a Te of -10C. That's is not bad for space heating but doesn't leave much room for DHW. This coolpack run was without a SLHX.

With a SLHX, the condensing temp on R290 increases to 65C and for R410 it goes up to 85C but the pressure is quite high. Under the same conditions the COP of R290 seems to be a bit higher.

I'm interested.

I'm trying to collect ideas HERE for what a CoolPack video tutorial should contain.

My thoughts, now that I've played with it a couple hours:

1. How to set up your initial conditions and equipment data (from white paper values);
2. How to make the stuff from step 1 match measured actual data (what to change and what not to change);
3. How to move between all the different windows and keep the data from step 1 or 2;
4. How to save what you have done and get it back later.

The issue I see with this program is that there's so much you can do with it. As a beginner, what is useful and what is not so useful is confusing.
