Abstract: Method for cool drying gas, in particular air, whereby this gas is guided through the secondary part of a heat exchanger (2) whose primary part is the vaporizer (3) of a cooling circuit (4), which consists in measuring the ambient temperature (Tamb), as well as the lowest gas temperature (LAT) or the dew point, and to switch the cooling circuit (4) on and off on the basis of these measurements in order to always maintain the lowest gas temperature (LAT) or the dew point between a pre-determined minimum and maximum threshold value, and whereby pre-determined threshold values are calculated on the basis of an algorithm which is a function of the measured ambient temperature (Tamb).

Abstract: Device for cool drying comprising a heat exchanger (2) whose primary part is the vaporizer (3) of a cooling circuit (4) which also includes a compressor (6) driven by a motor (5), a control device (16) for this motor (5) and measuring device (17) for the lowest air temperature (LAT), measuring device (18) for the ambient temperature (Tamb) and a flow meter (19), whereby this control device (16) can be at least switched in a first user mode in which the cooling circuit (4) is only activated when the gas flow exceeds a preset value and a second user mode in which the lowest air temperature (LAT) is maintained within a certain range by controlling the cooling circuit (4).
