Abstract

The invention is related to the control of temperature and relative humidity of the internal air in an equipment space (10), especially in a space for electric or telecommunications equipment. The temperature is controlled by changing the cooling power directed to the equipment space by the cooling equipment (13) included in the equipment space in such a way that the temperature of the internal air remains within the allowed temperature range defined by the requirements of the equipment located in the equipment space. The relative humidity of the internal air in the equipment space is controlled by using the same cooling equipment and by additionally keeping the temperature at such a level that the relative humidity of the internal air remains within the allowed value range defined by the humidity requirements of the equipment located in the equipment space. In order to implement the control by using as simple equipment as possible, the environmental conditions of the geographical location of the equipment space are used as a basis for selecting the value range for the absolute humidity, the value range corresponding to the said conditions, the selected value range and the humidity requirements of the equipement are used as a basis for defining the first temperature range allowed for the internal air in the equipment space, the defined first temperature range and the temperature requirements of the equipment are used as a basis for selecting the minimum and maximum temperature values allowed for the internal air in the equipment space, and both the temperature and the relative humidity are controlled solely on the basis of a control message given by a sensor measuring the temperature, by keeping the temperature between the minimum and maximum values selected.
