A method for condensing a vapor, comprising: - providing the vapor having a first dew point; - providing a condenser liquid, and cooling the condenser liquid to below or near the first dew point; - bringing the vapor and the condenser liquid into contact with each other, and thereby cooling the vapor to below or near the first dew point; and - causing the condenser liquid to flow and/or fall, thus causing a parallel flow of the vapor, such that the vapor is supplied and is cooled by contact with the condenser liquid, and wherein non-condensed vapor, which has a second dew point, is subsequently discharged; - further cooling the non-condensed vapor using a Peltier element after it has been in contact with the condenser liquid to below the second dew point; - precooling the vapor by bringing the vapor into heat exchanging contact with the further cooled, non-condensed vapor which has been in contact with the condenser liquid, wherein the vapor at least partially condenses into a condensate which is taken up by the condenser liquid and a secondary condensate is extracted from the non-condensed vapor, and wherein the condenser liquid is substantially the same fluid or compound as the vapor, and wherein - the vapor and the condenser liquid are brought into contact with each other within a housing; - the vapor is supplied via a vapor supply opening in the housing; - the non-condensed vapor is discharged via a vapor discharge opening; and wherein - the condenser liquid with the condensate and secondary condensate taken up therein is collected (10,13). - providing the vapor having a first dew point; - providing a condenser liquid, and cooling the condenser liquid to below or near the first dew point; - bringing the vapor and the condenser liquid into contact with each other, and thereby cooling the vapor to below or near the first dew point; and - causing the condenser liquid to flow and/or fall, thus causing a parallel flow of the vapor, such that the vapor is supplied and is cooled by contact with the condenser liquid, and wherein non-condensed vapor, which has a second dew point, is subsequently discharged; - further cooling the non-condensed vapor using a Peltier element after it has been in contact with the condenser liquid to below the second dew point; - precooling the vapor by bringing the vapor into heat exchanging contact with the further cooled, non-condensed vapor which has been in contact with the condenser liquid, wherein the vapor at least partially condenses into a condensate which is taken up by the condenser liquid and a secondary condensate is extracted from the non-condensed vapor, and wherein the condenser liquid is substantially the same fluid or compound as the vapor, and wherein - the vapor and the condenser liquid are brought into contact with each other within a housing; - the vapor is supplied via a vapor supply opening in the housing; - the non-condensed vapor is discharged via a vapor discharge opening; and wherein - the condenser liquid with the condensate and secondary condensate taken up therein is collected (10,13). wherein the vapor at least partially condenses into a condensate which is taken up by the condenser liquid and a secondary condensate is extracted from the non-condensed vapor, and wherein the condenser liquid is substantially the same fluid or compound as the vapor, and wherein - the vapor and the condenser liquid are brought into contact with each other within a housing; - the vapor is supplied via a vapor supply opening in the housing; - the non-condensed vapor is discharged via a vapor discharge opening; and - the vapor and the condenser liquid are brought into contact with each other within a housing; - the vapor is supplied via a vapor supply opening in the housing; - the non-condensed vapor is discharged via a vapor discharge opening; and wherein - the condenser liquid with the condensate and secondary condensate taken up therein is collected (10,13). - the condenser liquid with the condensate and secondary condensate taken up therein is collected (10,13).
