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
Many problems in the use and promotion of solar water heating systems

Many problems in the use and promotion of solar water heating systems

Solar water heating system (heater) is recognized as a relatively mature energy-saving product, and residents are happy to use it. However, it is actually difficult to promote in cities. The proportion of residential solar water heaters is still very low. The main problems are as follows: 1. The vast majority of solar water heating systems
Five types of regions of China's solar energy resources

Five types of regions of China’s solar energy resources

In order to make better use of solar energy in accordance with the different conditions of each region, Chinese researchers in the 1980s divided the country into the following five types of regions according to the total amount of solar radiation received by each region. 1. First-class area The annual sunshine hours are 3200~3300h. The

China’s solar resources

The border of China starts from the south of Zengmu Ansha in the Xisha Islands near 4°N latitude to the north to the heart of Heilongjiang River north of Mohe, Heilongjiang Province at 53°31’N latitud; and starting from the Pamirs plateau near 73°40’ east longitude in the west, and reaching the confluence of the Heilongjiang
Solar energy utilization and energy crisis and environmental issues

Solar energy utilization and energy crisis and environmental issues

Basic way of using solar energy The basic ways of using solar energy can be divided into the following four categories. 1. Light and heat utilization Its basic principle is to collect solar radiant energy and convert it into heat energy through interaction with matter for use. At present, the most used solar energy collectors
