This chapter shows a thermal load quantities based on physical values for a typical central Mexico location. The values for the home areas are common in the actual sizes for mediumprized houses for Temixco location. A conclusion for this scenario is that the medium-

There are two aqueous solutions candidates to operate solar air-conditioning for roof applications: aqueous lithium bromide and aqueous hydroxides. Based on the working pair selection, the size for the heat exchanger must be defined by following the given

The solar devices are selected as function of the temperature and final use. These temperature values are higher than 90°C. The entire system (heat exchanger and solar devices) was evaluated just in operation phase and compared with a conventional air-conditioning system for 3.52 kW. The life cycle assessment concluded that in construction phase, the solar system is
