BVUMBE, Tatenda J y INAMBAO, Freddie L. Operational evaluation of the performance of a solar powered absorption system in Pretoria. J. energy South. Afr. [online]. 2013, vol.24, n.3, pp.26-32. ISSN 2413-3051.
A 35kW pilot solar powered absorption cooling system was designed and constructed at Moot Hospital in Pretoria to investigate the technical and economic performance of the technology. Technically, the system produced an estimated 43.938MWh of cooling energy per year and reached a maximum power of 31kW and operated with an average COP of 0.63, which compares favourably with the 0.7 given by the manufacturer. This system has since been decommissioned. Unfortunately, due to a lack of standard design and operation information, the system was overdesigned. As a result, the economic performance of this technology could not be accurately determined.
