A chiller for cooling a chilling fluid that feeds an air-conditioning system of a building, the chiller comprising firstly a boiler-separator (100) for separating the two components of a refrigerant, one of which components is volatile, by heating and evaporation, and secondly a mixer (132) for reforming the refrigerant by evaporation and absorption. The boiler-separator comprises a combustion chamber (102) and a plurality of desorption-absorption enclosures (104, 106, 108, 110) extending concentrically around the combustion chamber, the outlet duct (110b, 108b, 106b) from the desorption portion or desorber of any one enclosure being connected to the inlet duct (108a, 106a, 104a) of the desorber of the immediately preceding enclosure via a first heat exchanger (118, 120, 122), the outlet duct (104b) of the desorber of the first enclosure and the inlet duct (110a) of the desorber of the last enclosure being connected to the mixer (132), and the outlet duct (104c, 106c, 108c) of the absorption portion of absorber of any one enclosure likewise being connected to the inlet duct (106d, 108d, 110d) of the absorber of the immediately following enclosure via a second heat exchanger (124, 126, 128), the inlet duct (104d) of the absorber of the first enclosure and the outlet duct (110c) of the absorber of the last enclosure being connected to the mixer (132).
