GALLEGOS, Ricardo O; VELAZQUEZ, Nicolás L  y  LUNA, Aníbal L. Dynamic Simulation and Comparative Study of Several Systems of Evaporative Cooling for Mexicali, México. Inf. tecnol. [online]. 2010, vol.21, n.2, pp.45-58. ISSN 0718-0764.

The design and evaluation of several configurations of evaporative cooling systems for air conditioning of a dwelling for low-income sectors in Mexicali, Mexico using simulation with TRNSYS 16.A  is presented in this paper. The configurations studied include direct as well as indirect evaporative cooling with heat exchange and also systems with solid desiccant. The main rating parameters to classify the different configurations are the internal comfort conditions, the efficiency and the number of required equipments. The results show that the best configuration is one that includes a heat exchanger that pre-cools the air inlet stream with a cooling stream delivered by air coming from the dwell, but there is a small fraction of the time during the day that comfort is not met. If thermal comfort is to be met during the whole day, solid desiccant systems are the best choice.

Palabras clave : evaporative cooling; climatic data; air conditioning; solid desiccant systems; dynamic simulation.
