ABSTRACT:
An improved evaporative air conditioning device which in the cooling phase subjects the air to be treated to evaporative treatment. Prior to evaporative treatment the air to be treated is enthalpically heated utilizing radiant solar energy or other artificial heating to lower the water content per unit of volume and also lower the wet bulb temperature. In the preferred embodiment, a heat absorbent material is placed adjacent the inlet ducts to the unit. In the heating phase, the device is automatically controlled to provide solar induced heating during periods when sufficient solar energy induced heat is available.
