The appts. incorporates a boiler (1) for evapn. of the cold medium, a condenser (2) for condensing the cold medium, a throttle device (3) for lowering the pressure in the cold medium, a cooling unit (4) for evapn. of the cold medium, an absorber (5) for absorbing cold medium coming from the boiler (1) outlet side (12), a container (6) acting as fluid lock, and a pump (7) for moving cold medium back to the boiler input side (11). - In the appts. low pressure side after the throttle (3) is cold medium and an absorbent together with an inert gas non-condensable at ruling pressure and temp. conditions, thereby counteracting cavitation in the pump (7). The boiler (1) is driven by solar heat, and a heat exchanger (80 has a first coil (81) coupled between the pump (7) output side (72) and the boiler (1) input side (11), and a second coil (82) coupled between the boiler (1) output side (12) and an input (52) on the absorber (5). |
