The present invention relates to a method for chilling a building comprising the steps of: Heating a working solution contained in a solar panel using solar radiation, Separating the heated working solution in vapor 10 and a concentrated working solution, Condensing the vapor to liquid refrigerant, Evaporating the liquid refrigerant, (i) in a building to be chilled or (ii) outside a building to be chilled, wherein the cooling obtained by evaporation is transferred to a cooling liquid outside the building and transported to the building to be chilled for delivery of the cooling, Ab-15 sorbing in an absorber the vapor in the concentrated working solution, and Returning the working solution to the first step.
