Has anyone looked at this ?
Seems counter intuitive

Nothing new I think, there's been lots of 'solar' air conditioning pushed over the years.
Can't remember anybody on here having used it though.Brian - Newton Abbot, Devon, UK

As they have patents on the idea I don't think this is old tech.

Re: https://www.solxenergy.com
the old thread has been closed but I think it should be opened up again for discussion. It seems the case studies are proving it to work...?

I'm curious as the case studies appear quite conclusive and independent. if you have a technical argument other than just poo poo'ing it because it doesn't sound 'right' please feel free to shoot it down technically as I'm interested in it

Re: https://www.solxenergy.com
Let's have a look at their statements.
1. Compressor heats refrigerant and solar panel will assist him to do that. This is wrong. Compressor compresses refrigerant and refrigerant temperature increase is side effect. It doesn't matter how much you heat refrigerant, it will not liquefied in condenser unless it will be compressed.
2. Delta T will increase. Condenser delta T is temperature difference between condensing temperature and air temperature. 105C is not condensing temperature. This is temperature of super heated refrigerant. Like in any condenser this refrigerant will be cooled down to 50C to initiate condensation process.
How do they created all numbers to show that this approach save energy? I don't know but it can be reduction of refrigeration loads or they just install regular solar panels to produce electricity and offset energy used by refrigeration plant.

Re: https://www.solxenergy.com
If you reheat superheated gasses with an external source after leaving the evaporator, then you're moving horizontally moving to the right along the LP line of the log p/h. This super-superheated gas then enters the compressors. For me resulting in extreme discharge temperatures and lower COP because compressor needs tot pump even more expanded gas which didn't contributed to the cooling process.
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: https://www.solxenergy.com
the heating takes place in the discharge line.

Re: https://www.solxenergy.com
You can test this approach yourself. Put electrical heater in discharge line of the existing system and energy use should drop. Don't count energy used by the heater. However, I'm doubt that this will happen.
Regarding independent testers. I used to believe my eyes (knowledge and experience). If I see it is red, I believe it is red and doesn't matter how many independent tester tell that this is green. I don't see any engineering explanation of this "phenomena".

Re: https://www.solxenergy.com
No nor me but there seems to be a bank of test cases
"Richard.........Its no joke the technology reallys works and wroks great. Here is a link to the website case study files and attached are just 2 of our own case studies here in The Bahamas and hope this helps."
