New Johnson Controls chiller solution collects 75% solar energy

April 2, 2013 - Johnson Controls claims its new chiller solution with hybrid solar thermal and photovoltaic (PV) technologies convert 75% of the sun’s rays into energy, compared to 15% efficiency in a traditional PV system. According to Johnson Controls, solar cooling offers a compelling value proposition for building owners by reducing both peak time energy costs and demand charges. The solution uses the York Absorption Chiller and features PV waste-heat recovery technology, and qualifies for utility incentives across North America, where cooling demand places a significant stress on the power grid, driving up electricity rates, it says. The solar-cooling solution integrates into a building controls system, including the Metasys building management system. It generates hot water for the absorption chiller to air condition buildings and electricity to reduce demand from the power grid.
