自1973年石油危机以来,利用太阳能的技术开发,在全世界活跃起来。现在使用250℃以上的高温太阳热发电,几乎到了最后阶段。今后100℃～250℃的中、高温工业用太阳能供热装置的开发,正在成为中心课题。本文介绍日立制作所研制的工业用太阳能集热器,可提供印染业用的130℃热水。它是以真空玻璃管内置反射镜集光、用热管集热的集热器。 Since 1973, the oil crisis, the use of solar energy technology development, active in the world. Now use of high temperature solar thermal power generation above 250 ℃, almost to the final stage. In the future 100 ℃ ~ 250 ℃ in the medium and high temperature industrial solar heating device development, is becoming a central issue. This article describes the Hitachi production of industrial solar collectors, can provide printing and dyeing industry with 130 ℃ hot water. It is a vacuum glass tube built-in reflector set collector, collector with a heat pipe collector.
