“…Experimental correlation for η I (at volumetric flow of 4 L/min) according to the ASRAHE 93-1986 (RA 91) standard is shown in Equation (1). The collector thermal performance was reported by Ibarra-Bahena et al [40]. The parabolic trough collector (PTC) is able to track the sun and concentrate the solar radiation into a focal line.…”

The present study reports the experimental results of a parabolic trough collector field and an absorption cooling system with a nominal capacity of 5 kW, which operates with the ammonia-lithium nitrate mixture. The parabolic trough collectors’ field consists of 15 collectors that are made of aluminum plate in the reflector surface and cooper in the absorber tube, with a total area of 38.4 m2. The absorption cooling system consists of 5 plate heat exchangers working as the main components. Parametric analyses were carried out to evaluate the performance of both systems under different operating conditions, in independent way. The results showed that the solar collectors’ field can provide up to 6.5 kW of useful heat to the absorption cooling system at temperatures up to 105 °C with thermal efficiencies up to 19.8% and exergy efficiencies up to 14.93, while the cooling system operated at generation temperatures from 85–95 °C and condensation temperatures between 20 and 28 °C, achieving external coefficients of performance up to 0.56, cooling temperatures as low as 6 °C, and exergy efficiencies up to 0.13. The highest value for the solar coefficient of performance reached 0.07.

“…A fraction of the solar radiation is transferred to a fluid, which flows inside the absorber pipe [15]. The PTC design was based on the works published by Jaramillo et al [39] and Ibarra-Bahena et al [40]. The material and manufacture process considered the Jaramillo's design and were installed at the CIICAp.…”

“…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.
