    摘要: A heat storage apparatus has a tank (1) containing a heat storage medium (5) and having an upper region and a lower region holding heat storage medium at respective temperatures above and below atmospheric temperature. To reduce heat losses and increase flexibility of use, an intermediate region is maintained between the upper and lower regions at a temperature between the upper and lower temperatures. The desired temperature of the intermediate region is maintained by heating or cooling its heat storage medium, for example by use of an otherwise unused low-grade heat source.

    摘要: The invention relates to a distilling apparatus in which an evaporation section (10, 60) which heats raw water (100) and causes the generation of vapor (200) from said raw water (100), and a hydrophobic porous film (30) through which the thus generated vapor (200) is filtered are separately provided. Because vapor (200) separated from the raw water is supplied to one surface of the hydrophobic porous film, the proportion of the vapor relative to the fluid supplied to that surface of the film (30) can be increased, thereby enabling the efficient filtering of a large amount of vapor through the film (30). In addition, because the temperature of condensed water obtained by cooling the vapor (200) can be kept in the vicinity of the boiling point thereof, any gases and volatile substances contained in the raw water (100) are prevented from dissolving in the distilled water, there­by enabling the production of extremely pure distilled water.

    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: A method and system of converting low-temperature energy into high-temperature energy comprises steps of concentrating a high-boiling liquid (3) diluted with a low-boiling liquid through evaporation of the low-boiling liquid; condensing the vapor (2) of the low-boiling liquid through its absorption into an intermediate heat medium liquid (5), while cooling, evaporating the diluted intermediate heat medium (4), and absorbing the vapor (2) generated in the last step into the concentrated high-boiling liquid (1), thereby generating dilution heat and phase change heat. The intermediate heat medium (5) has the property that the difference between the saturation temperature thereof and the saturation temperature of the high-boiling liquid (1) becomes small under a low pressure and the difference between the saturation temperatures of both liquids becomes large under a high pressure.

    摘要: The present invention relates to a process for producing ultra-pure water, an apparatus for producing said ultra-pure water and a process for using the ultra-­pure water produced according to said process. More particularly, the present invention relates to a process for producing ultra-pure water which comprises boiling a raw water to vaporize off the volatile components from the raw water, subsequently generating steam from the water, contacting the steam with a hydrophobic, porous, gas-­permeable and liquid-impermeable membrane to make the steam permeate the membrane, and then condensing the steam, as well as to an apparatus for producing said ultra-pure water and a process for using said ultra-pure water.
