MM,
I thought that I was loosing this very interesting issue. Regarding links of appliances, we can revisit SunDanzer. <http://www.sundanzer.com/PDF/SunDanzer_Batt_Free_Tech_Sh.pdf>http://www.sundanzer.com/PDF/SunDanzer_Batt_Free_Tech_Sh.pdf At the beginning they say "The unit operates using a variable speed compressor, peak power tracking, thick insulation, and a internal thermal storage to optimize cooling efficiency.". They are actually describing what I have been saying so many times. It works for fridges and it works for large office buildings. The large efficiency gains are not because it runs from solar panel, because if it ran from a AC driven AC to DC converter, it would still be a very efficient fridge and outperform most fridges in the market with large margin, in the very worst case using 10W more. The large gains are from variable output and control methods. Then it have added insulation and thermal storage, instead of charging batteries, also very smart and necessary for a solar only driven unit. http://www.toshiba-aircon.co.uk/products/flysheets/DIGITAL%20INVERTER%20BROCHURE.PDF http://www.aar.co.nz/brands/toshiba.html http://www.eastsiderefrigeration.co.nz/Heat_Pumps.shtml Look at Inverter Technology. http://www.fujitsugeneral.co.jp/english/new/spl/spl.html http://www.infineon.com/cmc_upload/migrated_files/document_files/Others/Airconbrochure-2.pdf http://www.bdt.co.nz/comfortmaster/apps.asp http://www.bdt.co.nz/comfortmaster/apps.asp Search for air conditioner inverter technology or variants, you get a lot of non US sites. I was surprised about that. They are using a lot of marketing BS, but it is simple - DC driven compressor - and control to utilize it. I already explained how it worked. Have been used in large computer room AC systems for years, were it important to keep both temperature and humidity within certain limits. It is so long time ago, that I encountered the technology, that I do not remember when. Only needed development of consumer products. As I said "ready for use" energy saving and maybe a "silver bullet" type of technology. Have been there and known for many years, not a new and exiting technology, only a technology that does the job.. They say that the purchase price is around 10% of the life time cost, so you can easily claim that the first you buy would be paid back by savings in 3 to 5 years. VERY GOOD INVESTMENT IN ENERGY EFFICIENCY !!!!!!!!!
