太阳能热水器是目前太阳能利用中最成熟,应用最广的装置。近几年来,由于国际石油价格下跌的影响,资本主义国家太阳能热水器行业很不景气。如美国从事热水器生产的企业一大半都倒闭了。不少人担心国际太阳能利用的萧条景象会影响我国,而事实上我国的太阳能热水器却一直在稳步发展。“六五”期间我国太阳能热水器推广应用量每年以14—32%的速度递增。全国从事太阳能研究的科研单位已发展到138个,生产单位108家,几乎所有的省、市、自治区都在从事太阳能利用的开发工作。可以预见,太阳能热水器作为一种商品,将会有一个很大的潜在市场。为适应这一形势发展的需要,横向联合,走行业发展的道路势在必行。利用现状1980年以前,我国太阳能热水器推广应用累计量 Solar water heater is the most mature and most widely used device in solar energy utilization. In recent years, due to the impact of the drop in international oil prices, the solar water heater industry in the capitalist countries has been sluggish. For example, most of the companies engaged in the production of water heaters in the United States have closed down. Many people are worried that the depressing outlook of international solar energy use will affect our country. In fact, China’s solar water heaters have been steadily developing. During the “6th Five-Year Plan” period, the application of solar water heaters in China is increasing at a rate of 14-32% per year. The number of research institutes engaged in solar energy research across the country has grown to 138, with 108 production units. Almost all provinces, cities and autonomous regions are engaged in the development of solar energy utilization. It can be foreseen that solar water heaters will have a large potential market as a commodity. In order to adapt to the needs of this situation, it is imperative to integrate horizontally and take the development of the industry.
