Solar Assisted A/C
Solar Assisted A/C
(OP)
Greetings,
I run the energy programs for a company and recently one company came to us trying to sell us a "solar assisted" air conditioning system. http://www.solarcool.com/Products/Commercial.aspx
I know that Lennox has solar assisted A/C units but the solar panels are used for electricity. However, these guys claim that they can get up to 32 SEER on units by using panels on the
refrigeration cycle. I am having a hard time seeing the thermodynamic logic on this. Since I don't want to appear short-sighted and brush off this technology as a scam I turn to you guys.
Have any of you seen these systems working? Do you see any logic in their claims? Any help will be greatly appreciated.
Thanks!

There is a cooling process that works with heating by adding moisture to a scavenger air stream, but those guys seem to claim to improve a refrigeration cycle (since they also sell AC equipment)

You are judged not by what you know, but by what you can do.

whoever buys that for his employer should get fired immediately for incompetence.

odelgado, most of us appear to be quite short-sighted on that, so you should not be worried.
the issue can be reduced to the common situation in hvac technology: some manufacturers claims new technology, presents his logic how efficient it is, but there is no real-world experience on it. it all leads to client preferences - i would say 9 of 10 of clients I am talking with would prefer proven technology, one of ten prefers brand new concepts and is ready to take risks.
explain that to you clients. you cannot take own responsibility for manufacturers claims without referent examples.

sub_cooling and so increase the cooling effect. i hope you to understand me as my language is Arabic. i am Egyptian

If i wanted the condenser to get warmer gas, why would I not just make it smaller?
I must warn all the inter-cooler manufacturers that they have it all wrong and they need to built inter-heaters :)
why are we still discussing this? Can someone move that to the 100-mpg carburetor forum?

All that said, this looked interesting: http://www.australiansunenergy.com.au/solar_aircon... given that at least some of it appears that the AC uses hot water (i.e. storage tank) as a dump load to cool the refrigerant, though I've not looked into it that much. Certainly appears to make more sense than the other stuff being discussed.
RE: Solar Assisted A/C
It would make infinitely more sense if the A/C were allowed to dump its heat load as a preheater to the hot water supply. Cooling something with hot water sound inane, unless one were cooling a nuclear reactor, but even then, cold water would be better.

Absorption chillers aren't efficient unless you have cheap waste heat or potentially solar.
