Abstract

Methods and apparatii are provided for utilizing radiation as a resource. The apparatii are based on an adsorber containing adsorbing material capable of utilizing the infrared radiation for desorption of liquid from the adsorbing material and evaporator that contains mixture of liquids covers by thin layer of oil capable of operating under negative pressure or vacuum. A condenser is fluidically connecting the adsorber and the evaporator while pressure and steam gradient is kept within the apparatus. When liquid evaporates from the evaporator, the temperature of the liquid left in the evaporator is reduced and can exchange heat and cool ambient air. The apparatii can be used for many applications, some of them are disclosed.
