HEAT STORING APPARATUS

摘要

The apparatus for storing heat energy in the form of chemical energy comprises a first container (550) for a liquid medium (750) containing a non-volatile solute and a second container (150) for a liquid medium (760) containing the solute in a different concentration from that of the medium (750) in the first container (550). The containers (550, 150) are communicated through a pair of liquid repellent, porous membranes (1000, 1100), so that only the vapor can enter the opposite container (150, 550), while transferring heat energy.
