摘要： PURPOSE:To measure impurity content including trace amounts of soluble impurities in a pure water by so regulating that fine particles of insoluble impurities remaining after atomizing to be evaporated and vaporized become a size of a measurable limit for counting number of the particles and counting the number of the remaining particles. CONSTITUTION:A primary pure water 10 treated with a filter or reverse osmosis equipment is sent to a purifying unit 200 via a pump 100 and treated to be a purified water 15, and supplied to a use point 300. The purified water manufacturing unit 200 has an ultraviolet sterilizer 210 at a front stage and an ultrafilter 230 at the last of a polisher 220 disposed in this order. The ultrafilter 230 is used to remove insoluble fine particles. Water quality of the water 15 is measured by detecting soluble organic matter in the water by a sensor 350 installed in a tube, and measuring it by a TOC measuring unit on-line. Soluble inorganic matter in the water is also detected by a sensor installed in the tube, and a specific resistance can be measured by an electric conductivity meter on-line.

摘要： PURPOSE:To heighten the efficiency of the utilization of hot water, in the whole of the title system, by a method wherein both a measuring means whereby the amount of demand is measured and a control means whereby each of machines if controlled on the basis of the result of its measurement, are added, and thus any of an absorption refrigeration machine, a heat exchanger, a distillation apparatus and a hot water-producing means is operated. CONSTITUTION:A control part 60 controls following matters, that is to say, a temperature is detected by a temperature-detector 330 on a return pipe 33 for chilled water, and when the temperature is higher than a temperature preset, the flow of a route 21 and a route 1001 is increased by both a flow controller 1060 and flow controller 1210 on the route 21, and when the temperature is lower than that, the flow thereof is decreased. In addition, for the control of the amount of fresh water fed, the amount of the water stored in a water tank 410 is detected by a waterlevel gauge 420, and the amount of hot water fed to a distillation apparatus 40 through a route 104 by a flow controller 1040, corresponding to the amount of the water stored, is controlled. For the control of the hot water, the amount of water stored in a water tank 520 is detected by a waterlevel gauge 530, and its temperature is detected by a temperature detector 510 on a return pipe 51, and when the amount of water stored decreases or its temperature drops, the flow of a route 108 is increased by a flow controller 1080. As the result of it, the efficiency of the utilization of hot water is heightened in the whole of the title system.

摘要： PURPOSE:To flexibly cope with a variation in a load by providing a concentration difference utility heat accumulator in which high temperature refrigerant vapor of a circulation system of a compression type refrigerator is used as a heat source and low temperature refrigerant liquid of the circulation system is used as a cooling source. CONSTITUTION:In a compression type refrigerator in which refrigerant is sealed in a circulation system having a compressor 1, a condenser 2, an expansion valve 3 and an evaporator 4, a concentration difference utility heat accumulator in which high temperature refrigerant vapor of the system of the refrigerator is used as a heat source and low temperature refrigerant liquid of the system is used as a cooling source, is provided. That is, when a heat demand (heat load) is reduced, a compression refrigerating cycle concentrates the absorption liquid of the accumulator by excess hot heat and cold heat, takes the hot heat or the cold heat by using absorptivity of the absorption liquid when the heat demand is increased, and adding it to the cycle. Thus, the output of the cycle can be standardized to always continue a stable rated operation.

摘要： PURPOSE:To make high temperature heat collectable from exhaust steam by providing an absorber, which absorbs partly the waste steam of a steam turbine by an absorbent, and a flow path which allows a cooling medium to pass through successively in the order of a condenser and the absorber. CONSTITUTION:Waste steam one part 206 from a steam turbine 20 is fed to a condenser 29, cooled by hot water 209 and condensed. While the rest of waste steam 205 is fed to an absorber 28 via a valve 37 and absorbed by a rich absorbent 208 to generate heat with the hot water heated and collected as heat collecting water 210. Here a diluted absorbent 207, output from the absorber 28, is preheated in a heat exchanger 27 by an absorbent pump 30 thereafter fed to a regenerator 24 there heat-concentrated into the rich absorbent 208 which is precooled by the heat exchanger 27 thereafter returned to the absorber 28. Thus being possible to collect high temperature heat as the heat collecting water 210 from the waste steams 205, 206 from the steam turbine 20, a steam turbine system, which supplies electric power and heat by using thermal energy, can be presented.

摘要： PURPOSE:To prevent oxygen from being generated by electrolysis of water and the component parts of a methanol fuel cell from being deteriorated so as to enhance the reliability of the methanol fuel cell and make the cell life longer by causing methanol contained in an anolyte and water to electrically and chemically react with each other within a manifold in order to yield carbon dioxide gas and hydrogen gas. CONSTITUTION:When anolyte 50 is fed into a methanol fuel cell from an anolyte entrance 52 a fuel chamber 51 is filled with the anolyte 50 through the manifold 42 of a carbon separator 40 as a main pipeline and through a branching line 43, and when air 60 of an oxidizing agent is fed into an oxidizing agent chamber 61 a potential difference between the fuel electrode 20 and oxidizing agent electrode 30 of each single cell occurs so that the single cells are connected in series. Under these conditions, liquid short-circuit occurs as in the electrical equivalent circuit of a cell stack 3 so that a current is caused to flow through the anolyte 50. In this case, current flows first from an auxiliary electrode 87 having catalyst and a reaction occurs in the auxiliary electrode 87 so that carbon dioxide gas and hydrogen gas are produced. Thus generation of oxygen causing electrolyte corrosion of the carbon separator 40 is restratined and the life of a laminated cell device is extended.
