一、前言能源是影响四个现代化速度的重要因素之一。我国能源增长幅度低于国民经济增长幅度,所以经济的增长在很大程度上取决于节能工作好坏。我国在能源方面工作方针是实行开发与节约并重,而在近期内要把节能放在优先地位,对国民经济实行以节能为中心的技术改造和结构改革。蓄热器是重要的节能设备。早在三十年代,欧美各工业先进国家就已广泛应用蓄热器。能源危机以后,节能更显得重要,蓄热器就成为集中研究课题之一。 I. Introduction Energy is one of the important factors that affect the speed of the four modernizations. China’s energy growth rate is lower than the national economic growth rate, so the economic growth depends largely on the energy-saving work is good or bad. China’s energy policy is to implement both development and conservation, and priority should be given to energy conservation in the near future, so as to implement a technological reform and a structural reform that focus on energy conservation in the national economy. Accumulators are important energy-saving devices. As early as the thirties, the advanced industrial countries in Europe and the United States have widely used heat accumulators. After the energy crisis, energy conservation is even more important, and the heat accumulator has become one of the concentrated research topics.
