The present invention refers to a device for cooling down and warming up fluid. For each of cooling down and warming up, the device provides of at least one opening (1; 2) for emitting fluid (3), wherein the at least one opening corresponding to cooling down is such that emitted fluid falls or is splashed or sprayed through air. Moreover, the invention refers to a method of changing a temperature of fluid. According to this method, a device for cooling down and warming up fluid (3) is used, wherein fluid is emitted by one or more opening/s (2) corresponding to warming up, such that the emitted fluid is exposed to solar radiation; or fluid is emitted by one or more opening/s (1) corresponding to cooling down, such that the fluid falls or is splashed or sprayed through air. Thereby, an evaporation of the emitted fluid is intensified, due to which heat is extracted from the fluid which is, thereby, cooled down.
