This paper intends to show the development of a demonstrative and educational project of a system of air conditioning operated with solar energy, in which are used complementary energy efficient technologies that enhance its performance within the block of registration of the UPB, Research, development and investment to achieve a high penetration of efficient and clean air conditioning technologies. The development has been divided into 4 large phases, which start with the simulation of the refrigeration system, in which the software TRNSYS© has been used; Sizing and basic design of the refrigeration system; Search and selection of equipment p.e. pumps; Absorption machine, solar collectors, among others; Detail design of an air conditioning system with solar thermal energy, in which use is made of wáter cooling equipment by absorption, radiant panels and indirect evaporative cooler. Among the results obtained are the sizing and detailed design of the system and the acquisition of the absorption and evaporative cooling equipment supported in a simulated design when using the software TRNSYS© and MATLAB©. This allowed to determine the appropriate load levels for each of the equipment involved in the system, in addition to ensuring the parameters of power quality to meet the requirements of electric power and air conditioning.
