(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

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,
The development history of solar water heating

The development history of solar water heating

Solar water heating is the earliest technology developed and industrialized in the field of solar thermal utilization in China. So far, it has gone through three stages of development. (1) The initial stage (from the 1950s to the early 1970s): The development and utilization of solar water heaters in China began in 1958. At that
China's building energy consumption and the development of solar building applications

China’s building energy consumption and the development of solar building applications

China’s building energy consumption development status For a long time, the world’s energy has mainly relied on fossil fuels such as oil and coal. However, fossil fuels not only have limited reserves, but also produce a large amount of CO2 when burned, causing the earth’s temperature to rise and the ecological environment to deteriorate. What

The development speed and scale of China’s construction industry

After the founding of the People’s Republic of China, the process of urbanization in China has continued to accelerate and the level of urbanization has continued to increase. The acceleration of urbanization is mainly manifested in the rapid increase in the number of cities. In 1949, there were 132 cities in China. In 1978, the

6. Technical research Some European countries are not rich in solar energy resources, but due to the lack of conventional energy and strong environmental awareness, many countries are committed to the optimization of solar water heating systems. Through software simulation and experimental measurement, analyze the operation mode and parameter setting of each part of the

With the outbreak of the first oil crisis in the 1970s, most American and European governments and organizations began to promote the application of solar energy. In the early days, the main focus was the utilization of passive solar energy and solar thermal utilization (heating and domestic hot water). At present, it has gradually developed

Advantages of solar water heating system and its development trend in China

Advantages of solar water heating system For a long time, people have been aware of the role of solar energy, and have been working hard to study and use solar energy. In recent decades, under the dual pressure of energy crisis and environmental problems, solar energy has become the focus of people’s attention due to
