Eco Cute CO2 heatpump

[desA]

CO2 is just another refrigerant, and not a very good one. If it weren't for all of the environmental nonsense, nobody would be seriously considering using it.

It has a very serious problem when the Te,sat rises too high. Reason : this gets close to the critical temp for CO2. It plays havoc with line sizes & the pressure drops go through the roof - can be as high as 300%!

The bi-stability issue is a serious one & has to be carefully managed by the system controller. If not careful, the system can flip into a mode where little, if any, heat is pumped. The CO2 industry generally chooses to overlook, or to not discuss this fact.

There are 'issues' to be addressed here. CO2 is not a 'wonder technology'. I happen to like the fact that we can make hot water using CO2. But, of late, the aggressive marketing tactics displayed by the CO2 devotees have become a little unbearable. This is across the board - not only the current proponent under inquisition.

MF, thank you for your explanation and I agree your unit shown is a nice packaged unit for your intended market.. ....nice job.
desA....it is you that cannot back anything up you say...it seems you are like a little bird on a few peoples shoulders, and when they speak up, you chime in with them....never on your own with your OWN knowledge.....you state a few issues that you maybe read in one of your knowledge magazines, known about CO2 in a closed cycle that were addressed years ago in the development of this product. Bi stability and 3 point is a non issue here, and we do not overlook anything. One is not a manufacturer for over 80 years with worldwide installations, if they overlook critical or even not so critical issues. Our business is on repeat clients.
Show me your pictures, I'll show you mine...
And then there's Gary....one who claims that I relentlessy market my product here, from the same guy that has on EVERY post comment he makes a little ad for some product he is trying to sell...we don't have the choice of not seeing your ad everytime you write...seems like relentless marketing to me....upon Sherlocks further review of the product, it seems it is based on 12 to 15 year old technology...maybe you are missing the chapter on CO2 refrigeration?...time to update the material.....stop looking for the hanging "chad".....lol...The environmental issues are real, they might not be as big as some suggest...but common sense tells us we cannot pollute, use massive amounts of energy with little disregard for the earths cycle. I am not a "greenie", but these are real issues.

Coldwine, what's in fact your intention? If you come here to poke around a bit, then you better leave your sarcastic undertone in your messages.

I don't normally bother to rise to the personal attacks, but, it seems like this is now necessary. You know, here's a thought for you to think about in more detail. If a salesperson has to resort to attacking the customer, or someone who challenges their technical claims, then they are either imposters, or their claims have no substance.

Personally, I think that you are trying to use RE to stir up controversy over CO2 in an effort to pursue your own marketing agenda. Frankly, you have done nothing other than to prove yourself to be a snake-oil salesman & charlatan. If you were at all confident about 'your' product, or work, you would not attack as you do. You have, unfortunately, come across as an immature, petulant blowhard, activist, bleeding-heart type. You, in all likelihood, seem to have no product of your own. You have plagiarised the work of others, in a very amateurish manner, passing them off as your own product. This is IP theft.

For the record, my product brand name is registered under the natural initiative drive. I happen to subscribe to the idea of CO2 & alternative refrigerants, each with their own place, amongst the other refrigerants. I do not, however, subscribe to claims about CO2 that are simply marketing hype from a person who really has no idea on the subject matter at hand.

You & your tirades are in danger of bringing R744 into disrepute. You should think more deeply on this.

known about CO2 in a closed cycle that were addressed years ago in the development of this product. Bi stability and 3 point is a non issue here, and we do not overlook anything.

All well & good. Then, please explain for the RE readership what the specific remedies are/were for the bi-stability, or multi-stability phenomenon. This would be helpful.

One is not a manufacturer for over 80 years with worldwide installations, if they overlook critical or even not so critical issues. Our business is on repeat clients.

Another unsubstantiated claim. You seem to be dreaming.

Show me your pictures, I'll show you mine...

You have not yet shown a single set of calulations to back up your claims. I expect that you will continue to bluster on, but never produce anything of substance, simply because you don't have the faintest clue.
