A device for realizing a cooling effect in a space comprises: a housing with a heat-conducting wall, which housing bounds a chamber through which air can flow; an air inlet which connects to the chamber and to said place, —an air outlet connecting to the chamber; air transport means for transporting air from the air inlet via the chamber to the air outlet; and moistening means for moistening the inner surface of the wall; this such that air supplied by the air transport means is introduced into the chamber via the air inlet, passes along the moistened inner surface of the wall in the chamber and is discharged from the chamber via the air outlet, whereby the water present on the inner surface of the heat-conducting wall evaporates and is entrained by the air flowing by, and the wall is cooled.

1. A device for realizing a cooling effect in a space, wherein the space may be an accommodation area, an office space, a living room or a cab in a means of transport, comprising: a housing with a heat-conducting wall, which housing bounds a chamber through which air can flow, wherein the heat-condu
1. A device for realizing a cooling effect in a space, wherein the space may be an accommodation area, an office space, a living room or a cab in a means of transport, comprising: a housing with a heat-conducting wall, which housing bounds a chamber through which air can flow, wherein the heat-conducting wall is facing the space such that the space is cooled by radiation absorption;an air inlet which connects the space to the chamber and through which only air from the space travels into the chamber, wherein the air entering the chamber is untreated air from the space;an air outlet connecting to the chamber through which air exits from the chamber;air transport means for transporting air from the space through the air inlet via the chamber to the air outlet; andmoistening means for moistening an inner surface of said wall with an evaporable liquid;such that all of the air from the space transported by the air transport means is introduced into the chamber via the air inlet, passes along the moistened inner surface of said wall in the chamber and is discharged from the chamber via the air outlet, whereby evaporable liquid present on the moistened inner surface evaporates and is entrained by the air flowing by, and said wall is cooled, but to a temperature never less than the dew point of the air in the space, the heat-conducting wall performing both functions of bounding the chamber and cooling the space by radiation absorption. 2. The device as claimed in claim 1, wherein the air outlet debouches outside the space for cooling. 3. The device as claimed in claim 1, wherein the wall is disposed horizontally. 4. The device as claimed in claim 1, wherein the housing is embodied as a hollow panel with a linear dimension transversely of the wall amounting to a maximum of 1/10 of a representative linear dimension. 5. The device as claimed in claim 4, wherein the linear dimension is selected from the group comprising a length and a width of said wall. 6. The device as claimed in claim 1, wherein said inner surface is embodied such that water disperses thereover without droplet formation. 7. The device as claimed in claim 6, wherein said inner surface is subjected beforehand to a corona treatment. 8. The device as claimed in claim 6, wherein said inner surface is provided with a hydrophilic cover layer. 9. The device as claimed in claim 6, wherein said inner surface is provided with a porous cover layer. 10. The device as claimed in claim 9, wherein the porous cover layer is selected from the group comprising cement and a fibrous mat. 11. The device as claimed in claim 1, wherein the moistening means comprise a number of drippers or sprayers. 12. The device as claimed in claim 1, wherein means enlarging the heat-conducting surface area are added at least to the inner side and at least to a part of the heat-conducting wall, said surface area-enlarging means being in direct thermal contact with the wall. 13. The device as claimed in claim 12, wherein means enlarging the heat conducting surface area are fins. 14. The device as claimed in claim 1, wherein the surface area-enlarging means are added to the inner surface of the wall. 15. The device as claimed in claim 1, wherein the moistening means are only active in an upstream zone of the wall such that the air cooled in this zone cools a remaining downstream zone of the wall. 16. The device as claimed in claim 1, wherein the air transport means is a fan means. 17. The device as claimed in claim 1, wherein the evaporable liquid is water. 18. The device as claimed in claim 1, wherein the means of transport is one from the group comprised of a car, a boat, and an aircraft. 19. The device as claimed in claim 1, wherein the housing is embodied as a hollow panel with a linear dimension transversely of the wall amounting to a maximum of 1/20 of a representative linear dimension. 20. The device as claimed in claim 1, wherein the housing is embodied as a hollow panel with a linear dimension transversely of the wall amounting to a maximum of between 1/30 to 1/50 of a representative linear dimension.
