<p>The invention relates to a method and a device for compression of gases, in particular of air, within a compressed air piping system. The air drawn in for the compressor is cooled below 0 DEG C. within a freeze-dehumidifer in a cooling channel. The supply of undercooled refrigerant into the freeze-dehumidifier is interrupted during the defrosting of the freeze-dehumidifier situated within the cooling channel for the air drawn in towards the compressor. The condensate appearing in the form of ice on the freeze-dehumidifer is separated thereby. The defrosting operation is terminated after a pressure of the refrigerant corresponding to a positive temperature of the freeze-dehumidifier is exceeded, or after a presettable period has elapsed. The pressure of the refrigerant is monitored in the suction pipe and if appropriate in the delivery or pressure pipe of the refrigerant compressor.</p> |
