“…Human resources to compare this technology are required; students with thermodynamics concepts to develop the calculation for each scenario from Physic or Engineering Bachelor programs need to be involved. Object-Oriented Programming is a tool that may be useful to include other dimensionless parameters as Flow Ratio [20].…”

Climate change has a huge challenge to 2050. Some renewable energies can be installed to reduce CO2 production. Unfortunately, the photovoltaic systems, wind energy, and ocean energy devices do not have direct thermal applications. These systems are useful for people’s electricity consumption. Absorption heat pumps (AHP) are thermal devices for increasing the temperature level from an energy source at medium temperature level, such as plane solar collectors, to another energy sink. The main problem with design, power calculations and device construction is a lack of education about this technology, which is more complex than compression heat pumps but with 90 % less electric energy consumption that would be supplied by photovoltaic cells. This paper shows an approximation for future engineers designing several absorption heat pumps to avoid global warming beyond the Paris Agreement. Future engineers should be encouraged to analyze this technology with this first and basic approach.

“…Type II AHPs are called "absorption heat transformers" also, and those have been reported for water distillation evaluation [41,42]. Some configuration has success like "solar ponds" coupled to "absorption heat transformer" [43][44][45] and solar systems [46] among others renewable energies [33].…”

It is impossible to transform the whole energy into useful work. It is impossible to increase the processes of cultivation of foods without water. It is impossible to separate all ions and minerals from water. Most of the real processes are thermodynamically irreversible. Calculations may indicate the fraction of efficiency of a thermal process. All the above mentioned facts have led to some proposals of cycles that exchange energy in order to produce a useful effect for the society. The key sustainable related parts are: to obtain water free of minerals or ions by distillation process. In this chapter, thermodynamic cycles will be explained for distillation using thermodynamic cycles of thermal machines called absorption heat pumps (AHPs). Distillation process offers to the AHPs an opportunity to diminish the consumptions of fossil fuels. The AHPs are able to work with 2% of mechanical energy to carry out a sustainable distillation process. Most of the energy of an absorption heat pump operation is thermal energy. The operation of the AHPs are defined with the coefficient of performance (COP); the variations of this parameter are shown as function of the different scenarios to obtain sustainable distilled water.

“…The sensors were connected to a data logger Agilent HP34970 with a personal computer. Measures of temperature were taken with the software HP-VEE Pro with programming directed to objects (Object Oriented Design OOD) focus in energy evaluation systems (Romero et al, 2007;Silva-Sotelo et al, 2010, Romero et al, 2013. Each one of the sensors was associated to the thermal balances to determine the thermodynamic behavior of the SBFBR in the cycle's operation.…”

This paper shows the experimental energy evaluation for a Sequencing Batch Fluidized Bed Reactor (SBFBR) anaerobic/aerobic. The SBFBR was installed for the treatment of the Direct Red 23 azo dye (DR23 C. I. 29160). The evaluation of energy was made for summer and winter seasons. DR23 was selected for study because is not quickly biodegraded. DR23 is one of the most used dyes in the textile industry and it is used to dye cotton, linen and rayon fibers. DR23 is stable to light, easily absorbed in the water and its degree of fixation in the fiber goes from 70 to 95%. The SBFBR was packed with granular activated carbon (CAG) as support of the biomass and as redox mediator for acceleration reaction rate by the transport of equivalent reducers between the electrodonor and electroacceptor compounds. A mixture 50/50 of activated sludge from two treatment plants was used as inoculums. Synthetic wastewater was composed with DR23 as substrate, 25 mgL -1 ; acetic acid as co-substrate15 mgL -1 and basal medium. The strategy of fixed efficiencies was used for the acclimatization of the biomass to the DR23 and to the changes of environmental anaerobic/aerobic. The reactor was operated by 160 days (253 cycles). The acclimatization was reached in 43 days in the cycle 27. The reaction time was reduced from 72 h to 24 h. The concentrations of azo DR23 were increasing of 25 to 200 mgL -1 with global removal efficiency of 95% of DR23. The reactor SBFBR anaerobic/aerobic was evaluated for the treatment of the DR23 azo dye and their metabolites secondary's that are aromatics amines. The thermodynamic evaluation was made for 27 cycles of operation of SBFBR in each operation temporary. Finally the total energy balance of process during summer and winter was evaluated and shows a energy consumption of 20 and 26 MJ respectly added to the SBFBR.
