(54) Wind/heat barrier


(57) Means for keeping down the energy consumption for cooling spaces open at their sides like indoor artificial skating-rinks and outdoor artificial skating-rinks. The means is a wind/heat barrier surrounding the space or the ground, consisting of a system of tubes arranged at a distance from one another through which a refrigerant flows and which acts as a heat exchanger.
The barrier at its top preferably contains a device dispersing moist over the tube situated underneath. The tubes are preferably provided with a coating with a high emission coefficient for longwave heat radiation.
