On an example of quartz sand – model macroporous solid by experimental way is shown, that constant inhomogeneous electrical fields essentially intensity the process of transposition of heat in a broad interval of moisturecontents, including hygroscopic and humid condition. Experimental dependence of effective thermal conductivity coefficient from moisturecontents эф(U) of sand obtained with the help of upgraded classical installation created by Babiev with average temperature on a sample 305 K is determined by a porous structure of a sample, form of connection and condition of an absorbed moisture. The different magnitudes эф for characteristic moisturecontents of sand are explained proceeding from possible mecha- nisms of movement of an absorbed moisture in conditions of a joint operation of an absorbed moisture in conditions of a joint operation of gradients moisture, temperature and electrical fields.
