Special Issue Information

Dear Colleagues,

Absorption systems have a great deal of potential in terms of boosting residual energy and reducing the demand for non-renewable energy sources. Recent studies of single and advanced absorption cycles (closed and open systems, new configurations and heat exchangers, coupling, activation, application, etc.) have significantly reinforced this research field. This Special Issue focused on absorption heat pumps for heating and cooling seeks to publish new knowledge on modeling, simulation, design, optimization, and experiments designed to understand parts of or whole systems, with the final aim being their real-world application.

The topics of interest include, but are not limited to, the following areas:

  • Absorption heat pumps;
  • Mass and heat transfer;
  • Solar thermal systems;
  • Optimization;
  • Artificial intelligence;
  • Machine learning;
  • Passive and dynamics heat exchangers;
  • Absorption heat transformers;
  • Automatization and control;
  • Solar heat storage systems;
  • Application of absorption systems;
  • Desorption and condensation;
  • Evaporation and absorption;
  • Combined cycles;
  • Hybrid cycles.

We show the performance of solar heating by coupling a Solar Water Heating System (SWHS) with an Absorption Heat Transformer (AHT) for annual continuous water heating. Solar Fraction (SF), Solar Heat Gain (SHG), and Auxiliary Heat (Qaux) were meticulously assessed for three Mexican cities located in the most characteristic climates (Saltillo, Toluca, and Tapachula). This rigorous assessment process ensures the reliability and accuracy of our findings. The potential reduction in net solar collector area (Ac) and storage tank volume (Vt) can be seen by comparing its annual performance to that of a conventional SWHS. Both configurations were designed to deliver the same hot water amount (0.019 kg/s, 1693.4 L/day, heating from 15.8 to 94.4 °C) and simulated using TRNSYS software version 16.01 concerning combinational systems. The results showed that SWHS-AHT achieved superior performance in solar water heating, achieving a higher SF (up to 99.6%) and SHG (up to 1352 kWh/m2-year) compared to the conventional SWHS. On the other hand, the SWHS-AHT achieved similar performance to a conventional SWHS with up to 60% less Ac. For instance, in Tapachula, a SWHS-AHT with an Ac of 150 m2 and a Vt of 18 m3 matched the performance of a SWHS with an Ac of 375 m2 and a Vt of 15 m3. Notably, both systems required the same Qaux. Thus, the Qaux requirement shows that SWHS-AHT is promising for industrial applications in Mexico, offering improved performance and a reduced footprint. Full article
