PartagerSolar cooling for large buildings in South Africa
A solar cooling solution to reduce energy costs for large buildings by combining high-efficiency chillers with hybrid solar thermal and photovoltaic (PV) technologies has been introduced in South Africa.
A solar cooling solution to reduce energy costs for large buildings by combining high-efficiency chillers with hybrid solar thermal and photovoltaic (PV) technologies has been introduced in South Africa.
The Johnson Controls system is said to be financially optimal for warm climates, given that it captures energy from the sun and uses a highly efficient absorption chiller.
The solution uses the York absorption chiller and features PV waste-heat recovery technology, converting 75% of the sun’s rays into energy, compared with about 15% efficiency in a traditional PV system.
The solar-cooling solution integrates into any 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.
Johnson Controls Systems & Service Africa highlights the fact that cooling demand in South Africa places a significant stress on the power grid and results in high utilities bills, especially for businesses. This chiller that incorporates PV technology is therefore considered optimal for South Africa, which has abundant sunshine and very high temperatures in summer.
Solar cooling enables building owners to reduce both peak time energy costs and demand charges.
