Type-ll absorption heat pump unit

The second-type absorption heat pump, also known as a temperature-boosting heat pump, utilizes a large amount of medium-temperature heat source to generate a small amount of high-temperature useful heat energy. It operates by using medium- and low-temperature heat as the driving energy, exploiting the thermal potential difference between medium- and low-temperature sources. The output heat quantity is lower than the input but at a higher temperature than the medium-temperature source, effectively upgrading part of the thermal energy to a higher temperature level, thereby improving the utility of the heat source. The Coefficient of Performance (COP) of second-type absorption heat pumps is always less than 1, typically ranging from 0.4 to 0.5. It does not require high-temperature driving heat sources but does require relatively low-temperature cooling water.
