This research had, as its principal objective, the application of the methodology to evaluate psychometric processes through the use of theory which combines the First and Second Principles of Thermodynamics into an adapted system of generating psychometric processes. With the Psychometric Processes System Generator (SIGEP) and other appropriate equipment, where air flow and electrical power from different systems of air conditioning were the most important variables. It was feasible to obtain data of dry and wet bulb temperature, from different locations of the SIGEP's control volume. These variables, plus the local atmospheric pressure, were enough to determine the state of the air inlet and outlet, which made possible the energetic and exergetic analysis. It was possible to conclude that the methodology based on the evaluation through the First and Second Principle of Thermodynamics was technically viable on the analysis of psychrometric processes. It can be observed that energetic evaluation, in almost every process generated by the SIGEP, provided less rigorous criteria than exergetic analysis. It can be also concluded that the equipments attached to the SIGEP had a high level of irreversibility due to the fact they were designed to meet a specific psychrometric condition, regardless of the level of efficiency at that time.
