The invention relates to a cooling and condensation device (10) of a greenhouse (1), preferably of a plastic film greenhouse, comprising at least one condenser (11) located in the greenhouse (1). The exterior (21) of the wall of said condenser is in contact with the air in the greenhouse (1) to be cooled and a cooling medium is applied to the interior (22) of the wall. According to the invention, the at least one condenser (11) is designed as a film tube that can be folded and consists, for example, of hollow articles (12), produced of a film material that can be folded, and stringed together, the tubular condenser (11) being deployable from a folded storage form to an elongated operating form.
