Green curtain system for external vertical surface of floor type construction

The invention relates to a green curtain system for an external vertical surface of a floor type construction. A frame of a uniformly planned air condensing unit is arranged on the external vertical surface of the construction; a condensate water collecting tank is fixedly arranged on the lower part of the frame; a filtering device is arranged in the condensate water collecting tank; the condensate water collecting tank is communicated with an air conditioner condensate water draining pipeline; an overflow pipe is arranged at the bottom of the condensate water collecting tank; an overflow port of the overflow pipe is connected with a rope for the cirrus growing; the bottom of the rope is connected with a planting tank on the top of the lower-layer air condensing unit; a longitudinal area between the adjacent upper and lower floors as well as the collecting tank at the upper layer and the lower layer air condensing unit is formed into a green curtain unit. The green curtain system provided by the invention is
