The development history of air source hot water heat pumps
A heat pump is a device that converts low-grade heat sources in air, water or soil into high-grade heat sources through power transmission. According to the different sources of heat ingestion, they are generally divided into air source heat pumps, water source heat pumps and ground source heat pumps.The name of the heat pump vividly metaphors its principle, that is, it is a kind of "pump", and what it carries is not water, steam, or oil but heat. It is not a heat conversion device but a heat transfer device. Therefore, its efficiency is not restricted by the heat conversion efficiency.
The theory of heat pump comes from the early Carnot cycle papers in the nineteenth century. In 1852, William Thomson put forward the idea of heat pump. In 1912, Zurich, Switzerland, successfully installed a set of heat pump equipment using river water as low-level energy for heating. This was the world's first water source heat pump system. The following decades were the early stage of heat pump research and development, but it caused high equipment costs. , Low reliability and widespread use of electricity, in the 1960s
The heat pump industry entered a stage of stagnation until the energy crisis broke out in the 1970s. People re-recognized the characteristics of heat pumps to save energy and recover low-temperature waste heat, and they paid more attention to the research work of heat pumps. The 1990s was a mature development period for heat pumps. Countries such as Japan, the United States, the United Kingdom, Singapore and other countries have widely used heat pump systems. Heat pump technology has been widely used in the industrial field, in terms of energy conservation and environmental protection.
Plays a major role. By the beginning of the 21st century, the air source hot water heat pumps market has been very prosperous, and the use of air source heat pump technology to produce domestic hot water has been widely used in southern China.
With the mature development of air source heat pump technology and huge market demand, it is entirely possible that it will become the mainstream of the water heater market in the near future. Air source hot water heat pumps are spreading rapidly with the momentum of vigorous development.
