Fresh Network has introduced solar Venetian blind air conditioner before, so it is no longer fresh. However, this Venetian blind air conditioner is different. It uses water as coolant which flows in the hose of the blind. With the evaporation of water, it absorbs the heat in the air, thus playing a cooling role naturally. However, compared with the solar Venetian blind air conditioner, it is unknown whether the cooling effect is better or not.
