The History of Heat Pump Development

In 1824 French scientist Sadi Karnot firstly proposed the Carnot Cycle Principle, marking the origin of heat pump technology. In 1852 British scientist L. Kelvin raised the idea that the chilling device could be used for heating. He firstly employed Inversed Carnot Cycle to heating. Afterwards, numbers of scientists and engineers studied heat pump, which last as long as 80 years.

In 1912 a set of heat pump using river water as heat source was installed in Swiss as an air heater. From 1940s to 1950s heat pumps had a rapid development. Household heat pumps and commercial heat pumps broke into the market. In 1970s heat pumps faced their golden time. The study of heat pump was taken seriously by the countries. Heat pumps were widely used in the air conditioning field and industrial field. They played an important role in saving energy and protecting the environment.

In the 21 Century, “Energy Crisis” boosted the fuel price. Heat pumps helped relieve the tough situation. It became the most valuable new energy technology.
