Application status and existing problems of solar water heating system in China

Application status and existing problems of solar water heating system in China

Application status of solar water heating system in China Through the comparison of the above contents, it can be seen that the solar water heating system technology in other countries is more mature than China in terms of products, technology, and use. While China has an absolute advantage in terms of usage, solar water heating
The development characteristics of solar photovoltaic power generation

The development characteristics of solar photovoltaic power generation

(1) China’s key technology mainly relies on foreign introduction, and its R&D and independent innovation capabilities are weak. The development of China’s photovoltaic industry basically relies on the introduction of foreign equipment and production lines, and then through digestion, absorption and re-innovation to improve localization capabilities. A number of key enterprises are paying more and
The development characteristics of solar refrigeration air conditioner

The development characteristics of solar refrigeration and air conditioning

(1) The scope and level of basic theory and experimental research are relatively wide. The remarkable feature of the development of China’s solar refrigeration and air-conditioning technology is that at the beginning of its development in the 1980s, a large number of high-level domestic research institutes and key universities participated. There are many units conducting

The development characteristics of solar heating

(1) Give priority to the development of passive solar heating technology in towns and rural areas. When China’s solar thermal utilization technology started to develop in 1980, the country’s overall economic strength and the living standards of urban and rural people were low. The country’s development policy in the field of solar heating and heating
The development characteristics of solar water heating

The development characteristics of solar water heating

(1) Based on China, integrate production, learning, and research into independent development to make breakthroughs in key technologies. A notable feature of China’s solar hot water technology is its independent intellectual property rights in key technologies. In order to improve the useful heat of solar energy of solar heat collection equipment, a vacuum solar heat
Current development analysis of solar photovoltaic power generation

Current development analysis of solar photovoltaic power generation

In the research and development of solar photovoltaic cell products, China has successively developed crystalline silicon (monocrystalline, polycrystalline) high-efficiency cells, amorphous silicon thin-film cells, cadmium telluride (CdTe), copper indium selenium (CIS), polycrystalline silicon thin-film cells, The technical level of silver paste development work for thermal batteries, etc. has been continuously improved, and individual projects (laser

Current development analysis of solar heating

(1) Passive solar heating. In the early development of China’s passive solar heating application, two major international cooperation projects played a huge role in promoting its technological progress: one was a UNDP-assisted project, and the other was a Sino-German cooperation project. In 1980, the United Nations Development Program and the National Science and Technology Commission
Current development analysis of solar hot water and solar refrigeration and air conditioning

Current development analysis of solar hot water and solar refrigeration and air conditioning

Solar water heating Solar water heating is a technology with independent intellectual property rights, the most mature technology, the fastest industrialization development in the domestic market, and the largest market potential in the field of solar thermal utilization in China. It is also China’s only self-developed technology that has reached the international leading level in
The development history of solar refrigeration and air conditioning and solar photovoltaic power generation

The development history of solar refrigeration and air conditioning and solar photovoltaic power generation

Solar refrigeration and air conditioning Because the application requirements of air conditioners and the supply of solar energy maintain a good consistency, that is, the hotter the weather, the greater the need to use air conditioners, the corresponding solar radiation is also larger. Therefore, solar refrigeration and air-conditioning is the earliest research field of solar
The development history of solar heating

The development history of solar heating

According to internationally used names, solar heating methods can be divided into two categories: active and passive. The active type is a forced circulation solar heating system composed of solar collectors, pipes, fans or pumps, terminal heat dissipation equipment and heat storage devices; the passive type uses the reasonable arrangement of the building orientation and surrounding environment,
