Absorption Heat Pump

New generation absorption heat pump

Countries around the world have abundant industrial waste heat resources, but waste heat in the low-temperature section is rarely utilized. In this case absorption heat pumps are very important.

The world's major industrial countries consume more than 10 billion tons of standard coal every year, but the overall utilization rate is less than 50%. Due to the lack of low-temperature heat recovery and utilization technology, more than half of the energy consumed is eventually discharged into nature in the form of industrial low-temperature waste heat through exhaust gas and waste water, causing serious damage to the atmospheric environment and also a huge waste of energy.

However, for low-temperature absorption heat pumps, a huge amount of industrial waste heat is exactly a huge amount of driving energy. If all are collected and utilized, it can almost solve the heating energy source for the whole society and save a large amount of primary energy consumption.

Low-temperature absorption heat pump is a new generation of absorption heat pump technology.

The first generation of absorption heat pump originated in the United States. Its working method does not consume electricity, but is driven by high-temperature heat energy. It uses lithium bromide as the absorbent and water as the refrigerant to form a working medium pair, so it is also called lithium bromide heat pump. Due to the abundant electricity in the United States at that time, this technology was not paid attention to and used. On the contrary, it is widely used in Japan, and it is precisely because of the influence of the country's energy policy that absorption technology has been fully developed.

A new generation of absorption heat pump technology has emerged: low-temperature drive technology to optimize high-temperature drive technology.

On the basis of the traditional absorption heat pump technology, it integrates the latest technologies such as the latest generation of structure, materials, and conduction for research, and strives to improve the performance of the absorption technology and reduce the temperature requirements for the driving heat source. The new technology has successfully reduced the minimum temperature requirement of the absorption technology for the driving heat source to be driven by 30oC hot water, thereby greatly improving the energy saving of the absorption technology and further broadening the application range of the absorption technology. The greatest significance of low-temperature absorption technology is to completely solve the problem of "industrial low-temperature waste heat cannot be efficiently recycled".
