Abstract (en)
Method for cooling supply air in the cooling system of a building, in which method the cooling water in the main circulation circuit (2) is cooled with a cooling compressor (1), and in which method cooling water is taken to the cooling radiator (3) from the main circulation circuit (2) for cooling the supply air, and in which method cooling water is taken to the room unit, such as to the chilled beam network (4) from the main circulation circuit (2) and mixed to the desired temperature, e.g. approx. 15 °C. The invention is implemented such that in an operating situation the cooling water of the main circulation circuit (2) is cooled to a temperature of over 7 °C, preferably to a temperature of approx. 12 °C, and such that in an exceptional situation such as when the supply air is humid, the temperature of the room unit, such as of the chilled beam network (4), is raised higher to prevent condensation and at the same time the temperature of the water of the main circulation circuit (2) is reduced lower.
