    摘要: 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.

    摘要: The invention relates to a portable, solar-thermal device for the treatment of drinking water from waste water, comprising an evaporation container that accommodates the waste water, a condensation apparatus having a flow connection to the evaporation container, and a separator arranged between the evaporation container and the condensation apparatus for separating and leading away the condensate obtained in the condensation apparatus. According to the invention, the separator has passage openings for the transfer of water vapor into the condensation apparatus, which is arranged on the top side of the device in the operating position of the device, and a drain opening for the condensate arising in the condensation apparatus, which drain opening can be connected to a collecting container, wherein the evaporation container, which is arranged on the bottom side of the separator, is designed as a flexible film bag.
