## 1 Introduction
The system was operated at generation temperatures from 75 \({}^{\circ}\)C to 110 \({}^{\circ}\)C obtaining evaporation temperatures as low as \(-\)11 \({}^{\circ}\)C. The reported system is able to produce up to 8 kg of ice per day. [PERSON] et al. [32] reported the operation of the same system presented by [PERSON] et al. [31] but utilizing the ternary mixture NH\({}_{3}\)-LiNO\({}_{3}\)-H\({}_{2}\)O. The results showed the system was able to obtain values for the solar coefficient of performance by 24% higher than the achieved when the system was operated with the NH\({}_{3}\)-LiNO\({}_{3}\) mixture. Moreover, with the NH\({}_{3}\)-LiNO\({}_{3}\)-H\({}_{2}\)O mixture, the lowest generation temperature required for operating the system was up to 5.5 \({}^{\circ}\)C less than those required with the binary mixture. [PERSON] et al. [33; 34] reported the results of a 10 kW solar absorption system for air-conditioning applications. This unit was able to deliver chilled water at temperatures near to 0 \({}^{\circ}\)C with thermal COP's approximated to 0.5. On the other hand, [PERSON] et al. [35] reported the development of two absorption cooling prototypes. One of them used a mass flow rate of water in order to remove the condensation and absorption heat; in the second prototype, the absorber was cooled by water while the condenser was cooled by a mass flow rate of air. The authors reported the thermal coefficient of performance resulted affected by the variations in the conditions of the water flowing through the condenser, the evaporator, and the generator. Both systems were able to produce chilled water at temperatures near to 15 \({}^{\circ}\)C when a mass flow rate of water was supplied to the generator at temperatures of 90 \({}^{\circ}\)C. The cooling capacity achieved was 12 kW. [PERSON] et al. [36] presented some part-load curves for the thermal and electrical coefficients of performance reported by [PERSON] et al. [35]. [PERSON] et al. [37] described the evaluation of an experimental ACS. In this system, the generator and the absorber were shell and tube heat exchangers with tubes with a helical coil configuration, the rest of the components were stainless-steel plate heat exchangers. The thermal coefficients of performance varied from 0.45 to 0.7 for a cooling capacity in the range from 0.52 to 2.52 kW. [PERSON] et al. [38] presented the experimental assessment for a water-cooled ACS were the generator and absorber also were falling film shell and tube heat exchangers, while the condenser, evaporator and solution heat exchanger were plate heat exchangers. The operating generator temperatures were varied from 80 \({}^{\circ}\)C to 100 \({}^{\circ}\)C, in the condenser the range for the temperatures variation was from 20 \({}^{\circ}\)C to 34 \({}^{\circ}\)C. The reported cooling capacities reached up to 4.5 kW for evaporation temperatures as low as 4 \({}^{\circ}\)C. The internal COP varied from 0.3 to 0.62. From the literature review presented, it can be seen that there are not solar systems for air-conditioning applications operating with mixtures different from the widely used NH\({}_{3}\)-H\({}_{2}\)O and H\({}_{2}\)O-LiBr. As it was stated before, the conventional mixtures have some well-known disadvantages, therefore a project titled \"CEMIE-Sol\" was conceived in Mexico in order to develop a solar absorption cooling system operating with the alternative working mixture ammonia/lithium nitrate, which can be used not only for air conditioning but also for refrigeration applications.
