A solar driven turbine loop for electricity production and cooling can advantageously be erected in sunny countries. Solar cells (1) with circulating water are heated up to 120~-160 ~C (2). Pumped (3) via the superheater (4) of a medium turbine loop to a medium vaporiser (19) and then in return for reheating. A second branch (27) of the hot water is led to accumulators (30- 31) for night operation. Superheated medium vapour is forced through a liquid separator (5) to the medium turbine (7) at high pressure and with high energy content. The turbine drives an electric generator (8), possibly also a heating pump compressor (10). If only the electricity generator is driven, an electrically driven heating pump is installed. The medium vapour expands to a lower pressure and th e medium energy content in the turbine and condenses in subsequent condenser (13). This with the aid of cool circulating water (38) which was cooled in an air cooled condenser (37). Condensed medium goes via a pressurising pump (16) through preheater (12) to vaporiser (19). Another branch (21) condensed medium passes an expansion valve (22) to a coolant battery (24). The medium now in vapour form (25) is sucked to the heating pump compressor (10). Forced thereafter (26) together with saturated medium vapour (20) to the superheater (4).
