Second Type Heat pump - Absorption Heat Transformer

AHT, Steam Generating Absorption Heat pump, also referred to as Absorption Heat Transformer or 2nd type heat pump, supplies high temperature hot water or steam as high as 100 ℃ by recovering Middle-temperature waste heat, below 90 ℃. Middle-temperature heat is supplied to the system, and a part of the supplied heat is transformed to high-temperature heat and another part of the heat is transformed to low-temperature heat and discharged to surrounding areas. In addition, the temperature of waste heat dumped at industrial sites can be raised to a usable high temperature through the second-class heat pumps, promoting energy preservation.

The second type absorption heat pumps which transform low-class heat to high-class heat and utilize it driving energy are called heat transformers. These transformers, in general, have operation cycles opposite to those of absorption chillers.

In this case, the temperature of hot water is low, because the acquired energy of hot water is larger than the energy of the drive heat sources but the temperature range of hot water is small. These heat pumps can be used for recovering the heat of waste hot water discharged during processes taking place in buildings or factories and supply the hot water where needed. These are the newest energy-saving machines which manufacture hot water or steam that is greater in temperature than 100℃ using waste steam or waste hot water as drive heat sources. People can get about 50% effective energy through adopting 100% waste energy. The coefficient of performance (COP) is generally 0.5 but people can reduce energy consumption through applying these devices in production processes because waste heat sources can be used as drive heat sources.
