Research on water-curtain wall passive evaporative cooling technology in hot and dry zone

Indoor water vapor diffuses outdoors under the action of partial pressure difference in hot and dry zone, and there is a certain amount of natural ventilation in indoor and outdoor air, both of which will reduce the relative humidity of the rooms. The passive evaporative cooling technology suitable for hot and dry zone is proposed, the cooling effect on the indoor environment of the water-curtain wall is studied by building a test bench model and conducting tests, and the feasibility of this cooling technology is verified. The change process of indoor air under the action of water-curtain wall is analysed, and the energy efficiency is compared with that of the traditional air conditioning method, which provides a theoretical basis for the optimization design of related equipment in the future.
