Floridas economic growth owes a lot to air conditioning Population growth, and the economic growth that came with it would have been severely curtailed if air conditioning did not exist to provide relief from the sweltering, humid, Florida summers. How do we keep growing and be green?
How important is A/C? 25% of all electricity used in Florida is exclusively for air conditioning and hot water in our homes. The demand for commercial cooling could represent 50% of all electrical usage in FL. (Source: DOE Regional Energy Profile, U.S. HOUSEHOLD ELECTRICITY REPORT Release date: July 14, & Florida Solar Energy Centerhttp://www.eia.doe.gov/emeu/reps/enduse/er01_so-atl_figs.html European expect that Renewable Heating and Cooling Supplied by Solar Thermal and Biomass can meet 25% of their Target of 20% from Renewable by (Source: European Union Renewable Energy Council) Other European info at
Solution: Thermally Powered Air Conditioning SOURCE:
What should qualify? Thermally driven Air-Conditioning, Heating, Dehumidification and Hot Water produced by: Solar thermal Biofuels Concentrating, Combined Heat & Power Solar Collectors: Both thermal energy (heat) and electrical energy generated should qualify for incentives
Concerns? Impact? Absorption cooling is a mature, developed technology and available today. Currently in use in large buildings, college campuses and factories Changes are required in the mechanical infrastructure of homes and some building to use thermal energy produced. Solar thermal A/C works best when needed the most during peak demand times.
Impact?: Reduction of Peak Demand Peak demand needs lots of peak power plants, which are costly to operate and raise electricity prices significantly. –If you had to pay the $16,000 of electricity network infrastructure for your $2000 air conditioner, you may think again – thats the case in Australia. Solar cooling can reduce the need for these power stations. Spain has a special rebate for Solar A/C, beyond what is given for flat plate collectors – –Spain believes that you absolutely need solar thermal to achieve Greenhouse Gas reductions. But when youve gone beyond Solar Hot water, then you need to tackle solar space heating. And as soon as you do space heating, youve got too much heat capture in summer, what to do with it?... Solution: solar cooling. With % of kW rebate, or a grant program. SOURCE: Solar Air Conditioning: Opportunities and Obstacles in Australia, Sept 2006, Warwick Johnston
Corporate Office: 4015 S. Dale Mabry Hwy Tampa, FL (813) West Coast Office: 2033 Gateway Place, 6th San Jose, CA (408) Economics? Cost? of Solar A/C Solar Thermal Air-Conditioning provides three times the rate of return of solar photovoltaic. Each ton of Solar Powered Air-Conditioning built in Florida creates between $5,000 to $10,000 in new, additional construction revenues and $100 per ton per year in maintenance services fees. SOURCE: Based on actual costs/estimates of 4 solar HVAC systems: (1) Tampa, FL-30kw 5-tons, (2) Brandon, FL-145kw, 20-ton w/waste cooking oil backup, (3) Tulsa, OK-2.5MW, 500-tons & (4) Santa Clara, CA-2-tons.
