Abstract
The present invention concerns a method for cool-drying gas containing water vapor, whereby this gas is guided through the secondary part of a heat exchanger (1) whose primary part is the evaporator (2) of a cooling circuit (3) which also contains a compressor (5) which is driven by an electric motor (4), a condenser (6), an expansion means (7) between the outlet of the condenser (6) and the inlet of the evaporator (2), and whereby the above-mentioned cooling circuit (3) is thus controlled as a function of the load that the cooling capacity is adjusted without any ice being formed in the evaporator (2), characterized in that the cooling circuit is controlled by adjusting the rotational speed of the motor (4).
