You are invited to join the San Diego Renewable Energy Society (SDRES) on Wednesday, April 14, 2010 at 7pm for a presentation by Dan Hendrickson, President of Libre Energy. This presentation will discuss the operation of Coolerado Indirect-Evaporative air Conditioning that due to its low energy requirement (~120 watts/ton) is easily powered with Solar PV panels.

The presentation will also discuss use of evacuated tube solar water heating for Domestic Hot Water, space heating and cooling. Space cooling is accomplished using a solar water heating system "waste heat" to power an ADsorption Chiller.

Employment of Solar PV, SWH, Coolerado and ADsorption Chiller subsystems in a zero energy HVAC system capable of operating in moderately humid climates will also be discussed.

Use of a dehumidifier system in conjunction with a Coolerado air conditioner and regeneration of dehumidifier desiccant with SWH system "waste heat" will also be discussed.
