Resumen

LUNA, Aníbal; VELAZQUEZ, Nicolás; GALLEGOS, Ricardo  y  BOJORQUEZ, Gonzalo. Solar Air Conditioning for a Housing Compound in Mexicali, Mexico. Inf. tecnol. [online]. 2008, vol.19, n.1, pp.45-56. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642008000100007.

The objective of the present work is to dimension and evaluate an absorption LiBr-H2O cooling system assisted by solar energy and natural gas for air conditioning of a group of housings in Mexicali, Baja California, Mexico. The analysis of the hourly, daily and monthly operating performance in the period with more cooling demand is carried out by mean of TRNSYS 16, and it is seeking the least collection area and the highest solar fraction; that which is translated in the minimum operation cost and initial investment. It was found that the system generates conditions of the space between comfortably warm and comfortably cold, according to ISO 7730 (2005), with 287 m2 of evacuated tubes which contribute 90% of the required energy. The system is technically feasible, since it covers the cooling demand during the summer period and it requires a similar collecting area to the available one in the housing compounds.

Palabras clave : absorption LiBr-H2O; solar fraction; thermal comfort; solar energy; air conditioning.
