The invention relates to a natural ventilating method with air conditioning function, which uses natural wind to drive the outdoor air via the air processing to be fed into building to realize the ventilation. When the natural wind force is not enough, it can use mechanical ventilating device. Said air processing process can be selected from refrigeration, heating, dehumidifying, humidifying, filtration, purifying, indirect vaporizing cooling, direct vaporizing cooling and heat recycle, etc. The regeneration of solution used in liquid dehumidifying can uses solar energy. The invention can fully uses regenerative energy as wind energy and solar energy to realize ventilation and air conditioning, to supply the energy saving and environment protection of building with wider application prospect. |
