Solar air conditioning is driven by solar evacuated tube collectors, which collect thermal energy from the sun. This energy is then transmitted into a solar absorption chiller by means of a heat transfer fluid (HTF). HTF is generally comprised of water and corn or propylene glycol and is designed for both efficient heat transfer as well as freeze protection in the winter. The HTF then passes into the solar absorption chiller, thus powering it and providing free, solar-powered air conditioning.
As mentioned several times above, solar conditioning is a highly-attractive climate control option because it allows property owners to cut costs by not using energy from the grid. For this reason, solar air conditioning is also quite environmentally friendly. Plus, the state-of-the-art systems offered here at Sun King work as well or better than traditional air conditioning systems in the sunny Hawaiian summer season.
