“…For avoid the redundant data in the model was defined the representative data using the expected improvement optimization (Gibelhaus, Tangkrachang, Bau, Seiler, & Bardow, 2019) Integrated optimization of design and control with the total cost or electrical efficiency like objective function in the sorption chillers was developed.…”

Throughout our lives we take different decisions, about our culture, our food, our likes, our future, and in some moments we decide to make some voyages of learning. On this road we learn a lot, even more than hoped for, in my case, as I received so many unexpected and valuable lessons that it now only remains for me to express my thanks. This master's degree is more than a new professional qualification for my curriculum vitae, it has been a life experience, since it taught me how to get lost and how to go back, to find myself. It taught me to let myself be guided and accompanied, reiterating that in this life all that we learn is useful, that all people who arrive in our lives have a lot to bring to us, and something too that one can contribute. And it was in this during this journey that I found so many beautiful and nice people that I haven't mentioned in these paragraphs. To them I express my deepest esteem and my sincere acknowledgment. Thanks to my quartet of classmates Cesar Garcia, Diana Grajales, Isis Hernández, and VictorLópez, because with them the postgraduate studies were amazing, filled with learning and laughter. I thank them for their support and friendship, the best possible example of the way such relationships can be built between professionals. A special acknowledgment to Diana Grajales because only somebody so in love with studying and chemical engineering can understand me and help me to rediscover my inspiration, thanks so much. To the teacher Adriana Villegas, thank you for giving me cardiopulmonary resuscitation in a time of agony, because when my PC was broken, she helped me with all her tools and time to allow me to continue.To my advisor Dr. Silvia Ochoa, the most intelligent person, the best teacher and person that I know, thanks for your lessons, advice, and mainly your patience and good talks about the academy and life, maybe I need another thesis to express to her all my gratitude. When I met my advisor, I said that I loved the modeling and simulation of processes and saw that with her I could learn a lot about the programing applied to chemical engineering. I wasn't wrong in my thinking, by contrast, I underestimated this, because not only had I met a great teacher with wide knowledge in mathematics, thermodynamics, control, simulation, amongst other areas of science, and other great quantity of mental capacities, but also I found an excellent person who shares her expertise, and shows more than just interest in her students but interest in the people who are her students, and she helps you to grow as such. Thank you for making sure my postgraduate studies were not just another technical stage, thank you for making me a better person and better professional, and mainly thank you for allowing me to get to know you, and for believing in me, because although I had bad days she always was my cornerstone, motivating and improving my skills and working on my weaknesses, and never allowing me to decline, reminding me of the reasons why I chose to research in modeling and simulation of p...

“…The final choice also needs to consider a full AdHT system with all auxiliary components, as shown for adsorption chillers. [52] However, an economic or environmental evaluation of a full AdHT system is beyond the scope of the current work, which focuses on the general potential for adsorption heat transformation around 100 C. In this spirit, we do not want to prefer one specific objective, but we choose a very flexible design regarding both COP exergetic and SHP. For the automatic selection of such a flexible design, Hollermann et al proposed the flex-hand approach applied in this work.…”

Globally, heat demand accounts for 71% of industrial energy consumption. [1] For example, the industry in the US requires 3416 PJ heat between 40 and 260 C, with 1755 PJ already in the temperature range between 120 and 160 C, and the industry in the European Union requires 626 PJ heat for temperatures below 150 C, with 116 PJ in the temperature range between 100 and 150 C. [2] Examples of such industrial processes and their process temperatures were summarized by Arpagaus et al. or Brückner et al. (Table 1). [2,3] Simultaneously, the global industry releases 31902 PJ of waste heat, with 42% occurring below 100 C as low-grade heat. [4] Transforming this low-grade waste heat from temperatures below to above 100 C could enhance industrial energy efficiency. Thereby, heat transformation has the potential to reduce both primary energy consumption and greenhouse gas emissions. [5] The low-grade waste heat can be transformed into useful heat with higher temperatures by mechanically driven vapor compression heat pumps or thermally driven heat transformers. However, classical heat pumps currently available are restricted to a maximum gross temperature lift of 50 K and a maximum condensing temperature of 130 C. [2,6] Vapor compression heat pumps for higher temperatures suffer from the lack of suitable working fluids. [2,6] Designs are often challenging for both the cycles (e.g., multi-stage cycles) and components (e.g., multi-stage compressors) due to high discharge pressures and temperatures. [2,6-8] To overcome these limitations, many researchers screen working fluids or improve the thermodynamic cycle design. For example, Mikielewicz and Wajs screened working fluids with low global warming potential for upgrading heat from 50 to 130 C. [6] Ethanol was identified as a promising working fluid in a singlestage cycle design, whereas multi-stage cycles generally seemed
