In the early nineteenth Century, the French scientist sadi Kano (Sadi karnot) first proposed the "Kano cycle" theory in the paper in 1824, which became the origin of heat pump technology. In 1852, British scientist Kelvin (L.Kelvin) proposed that the cryopreservation device could be used to heat the heat pump which was used for heating the reverse Kano cycle. He first proposed a formal heat pump system, which was then called "thermal multiplier". Since then, many scientists and engineers have done a lot of research on heat pumps for 80 years. In 1912, Zurich, Switzerland, successfully installed a set of heat pump equipment with water as a low source heat source for heating. This is the early water source heat pump system and the first set of heat pump systems in the world. The heat pump industry developed rapidly from 1940s to early 50s. The heat pump used by household heat pumps and industrial buildings began to enter the market, and the heat pump entered the early stage of development.

20世纪70年代以来，热泵工业进入了黄金时期，世界各国对热泵的研究工作都十分重视，诸如国际能源机构和欧洲共同体，都制定了大型热泵发展计划，热泵新技术层出不穷，热泵的用途也在不断的开拓，广泛应用于空调和工业领域，在能源的节约和环境保护方面起着重大的作用。

Since 1970s, the heat pump industry has entered the golden period. All the countries of the world have paid great attention to the research work of heat pump. Such as the International Energy Agency and the European community, the development plan of large heat pump has been formulated. The new heat pump technology is emerging in endlessly, the use of heat pump is also in the open development, widely used in air conditioning and industry. The field plays an important role in energy conservation and environmental protection.

21 世纪，随着“能源危机 ”出现，燃油价格忽升，经过改进发展成熟的热泵以其高效回收低温环境热能，节能环保的特点，重新登上历史舞台，成为当前最有价值的新能源科技。前国际热能署专门成立国际热泵中心，设立热泵推广工程（Heat Pump Programme），向世界上各国推广协调热泵技术的应用和发展。美、加、瑞典、德、日、韩等国政府均发出专门官方指引，促进热泵技术的社会应用。相对世界热泵的发展，中国热泵的研究工作起步约晚20-30年左右。新中国成立后，随着工业建设新高潮的到来，热泵技术才开始引入中国。

In twenty-first Century, with the emergence of "energy crisis", the price of fuel oil rose suddenly. After improving the mature heat pump to efficiently recycle low temperature environmental heat energy, energy saving and environmental protection, it has become the most valuable new energy technology. The former international thermal energy agency set up an international heat pump center to set up a heat pump extension project (Heat Pump Programme) to promote the application and development of heat pump technology to all countries in the world. The governments of the United States, Canada, Sweden, Germany, Japan and South Korea have issued special official guidelines to promote the social application of heat pump technology. Relative to the development of the world heat pump, the research work of heat pump in China started about 20-30 years later. After the founding of new China, with the advent of the new high tide of industrial construction, heat pump technology began to introduce into China.
