<p>A method for measuring and adjusting the temperature of surface ice in artificial ice rinks (1), in which water is frozen to ice with the aid of refirgerating channels (2) arranged in the rink and through which refrigerant is passed by means of a refrigerating system (3) and wherein the temperature of the ice is controlled by controlling the refrigerating power of the refrigerating system. The method is mainly characterized in that the surface ice temperature is measured with the aid of at least one sensor (8), which functions to measure infrared radiation from the surface ice. The signals produced by the sensor are processed in a control unit (9) which controls the refrigerating system (3) in a manner to bring the surface ice to a predetermined temperature. The invention also relates to an arrangement for carrying out the method.</p> |
