摘要：Reducing CO2 emissions and restraining dependence on nuclear power generation are serious concerns in the prevention of global warming since the Great East Japan Earthquake. To do so, it is necessary to use and expand green energy such as solar energy and to promote energy conservation. However in high-latitude regions, it is difficult to directly and effectively use solar power due to on insufficient amount of solar radiation. If steam can be generated from warm water at less than 373 K, it is possible to obtain steam by solar water heaters from weak solar radiation, hot springs and industrial waste warm water without the consumption of any fossil fuels. In this study, the authors have been developing a system which generates steam over 423 K from warm water at less than 373 K using an adsorption heat pump with a zeolite. Therefore, improved bench-scale equipment which generates steam continuously and the experimental results are mentioned.KeywordsSteam generationheat pumpzeoliteenergy conservationhot water1 IntroductionThe Japanese government has lowered its CO2 emissions reduction target in November 2013, however the trade deficit in 2013 enlarged to 13.7 trillion yen with fossil fuel imports reaching 28.4 trillion yen and the total imports of 84.6 trillion yen. These values indicate the need as a nation to reduce energy imports not only from a CO2 emissions reduction and a restraining dependence on nuclear power generation standpoint, but also from an economic one [1].
