Abstract: According to the news, the world is now implementing a low-carbon, energy-saving and environmentally-friendly life. Our country is also in line with the trend of development. Major cities have started the construction of low-carbon cities. One of the main reasons why global climate change threatens the survival and development of human beings is the excessive use of fossil fuels by humans. Cities are high-emission regions for carbon dioxide. Building low-carbon cities is the best model for future urban development.

More than 100 cities in China have successively proposed the development goals for the construction of low-carbon cities. The heat pump has the outstanding performance of low-carbon environmental protection and energy saving, and is now widely used in air-conditioning and industrial fields. In the aspect of energy conservation and environmental protection, it plays a major role. When using heat pumps, the discharged gases are non-toxic and harmless. Therefore, the construction of low-carbon cities is bound to accelerate the development of the heat pump industry.

According to relevant information, since the 1970s, the heat pump industry has entered a golden period. Countries around the world attach great importance to the research work of heat pumps. For example, the International Energy Agency and the European Community have formulated large-scale heat pump development plans, and new heat pump technologies have emerged. The use is also being continuously explored. It is widely used in air-conditioning and industrial fields and plays a major role in energy conservation and environmental protection. Relative to the development of the world's heat pump, the research work of China's heat pump started about 20-30 years later. After the founding of New China, with the arrival of a new upsurge in industrial construction, heat pump technology began to be introduced into China. After entering the 21st century, the rapid urbanization of China's coastal areas, the growth of GDP per capita, the 2008 Beijing Olympics, and the 2010 Shanghai World Expo have driven the development of China's air-conditioning market and promoted the increasingly widespread application of heat pumps in China. The development of heat pumps is very rapid, and the research of heat pump technology continues to innovate. The construction of low-carbon cities in various regions of the country will also promote the development of the heat pump industry in China.

It is understood that the heat pump industry started late in China, and development is also relatively slow. First, people's living standards improved and their awareness of environmental protection increased. More respected low-carbon cities to build a low-carbon life. This pursuit of a low-carbon life will accelerate the development of China's heat pump industry. The safety performance of heat pumps is also higher than that of general appliances, so people will be more pro-heat-resistant pumps.
