    摘要： Apparatus and method for carrying out heat transfer, and storage are provided. In a conduit system, there is a heat storage system (4,5) consisting of a mixture of a liquid first material (preferably oleophilic) and a second material (preferably non-oleophilic) not soluble in said first material and having a higher melting point than said first material. The heat storage system is capable of conversion to and fro between two states of which a first state is an emulsion in which said first material forms the continuous phase and said second material in the liquid state forms the internal phase and a second state is a slurry type state in which said second material is in the frozen state in the form of particles in said first material. A tank (1) stores the heat storage system. At a first location (2) of the conduit system, heat is removed from the heat storage system by converting it from said first state to said second state. At a second location (3) remote from said first location, heat is put into the storage system by converting it from said second state to said first state.

    摘要： The method and apparatus for concentration aqueous solution in accordance with the present invention is characterized in that a hydrophobic porous membrane (2) through which vapor (4) can permeate, but not liquid, is brought into contact with an aqueous solution containing a solute at a concentration of at least 30%, and the water contained in the aqueous solution at the interface with the membrane is evaporated and permeates through the membrane (2). A method and an apparatus of recovering temperature of an aqueous solution comprising an aqueous solution concentration step in which the aqueous solution is in contact with the membrane (2), the water being evaporated; and a dilution step in which the resultant concentrated solution (11) is diluted; wherein a temperature is obtained higher or lower than that of said aqueous solution The method and apparatus for concentrating an aqueous solution can be used as a means or apparatus for concentrating an aqueous solution in a dilution type of heat pump, and absorption type of heat pump or an absorption type of refrigerator. Aqueous solutions for high temperature outputs of dilution systems include aqueous solutions of sulfuric acid, nitric acid, etc., and for low-temperature outputs I include aqueous solutions of potassium nitrate, sodium nitrate, etc. and further for absorption systems include aqueous solutions of NaCℓ0 3 , lithium bromide, etc.
