Exergy analysis of a heat transformer for water purification increasing heat source temperature

Recycling waste heat energy using vapour absorption heat transformers: A review

“…The SSHT's ECOP shows similar trends to the COP, increasing (initially quite rapidly [8]) with an increase in the evaporator and generator temperatures before beginning to decrease [23,24], and increasing with a decrease in condensation temperature [24]. The ECOP also decreases slightly with an increase in absorber temperature (i.e.…”

“…The ECOP also decreases slightly with an increase in absorber temperature (i.e. the GTL), before beginning to fall off rapidly once some critical absorber temperature is reached [24].…”

Optimum performance of a double absorption heat transformer

“…Eqs. (4) and (5) indicate that the value of e EC1 and e EC2 are related to the inlet solution temperature of the absorber and the absorber-evaporator, respectively, as T gen stays unchanged. Furthermore, the e EC1 and e EC2 have different influence on the OAET although they are similar in variation trends.…”

“…The large consumption of the fossil fuel is not only unsustainable but also pollutes the environment. In this respect, many countries are investing a considerable amount of money to develop equipments to use energy efficiently and to apply to renewable energy [2][3][4][5][6][7][8]. Among these devices, absorption heat transformer (AHT) is very promising since it can utilize waste heat or renewable energy, like solar energy and geothermal energy, to provide high temperature heat [9][10][11].…”

Energy and Exergy Analyses of a New Combined Cycle for Producing Electricity and Desalinated Water Using Geothermal Energy

“…The outlet temperature of the Kalina cycle from the evaporator, depending on the design and operating conditions, can vary between 75 and 80 °C. This temperature range may be suitable for a LiBr/H 2 O absorption heat transformer in seawater desalination applications [24][25][26][27][28][29] but, to the best of our knowledge, this topic has not yet been investigated by researchers.…”
