ISAZA, CESAR A.; PILATOWSKY, ISAAC; ROMERO, ROSEMBERG J.  and  CORTES, FARID B.. THERMODYNAMIC ANALYSIS OF A SOLAR ABSORPTION REFRIGERARON SYSTEM USING MONOMETHYLAMINE - WATER SOLUTIONS FOR FOOD STORAGE. Rev.Bio.Agro [online]. 2010, vol.8, n.1, pp.18-25. ISSN 1692-3561.

This work reports the applicability of monomethylamine-water solutions in a solar absorption refrigerator for food conservation purposes in the rural regions of Colombia , where no electricity is available. A solar heating system using fíat píate solar collectors with a conventional auxiliary heating system is proposed. We have determined the COP of the solar single-stage absorption refrigerator as a function of the temperature in the different components of the cycle. The results indícate the system might be improved by better design on the solution heat exchanger, the evaporator and the rectifier. The theoretical results prove that the use of MMA-W solution can be driven bylow-grade thermal energy such as solar energy.

Keywords : Solar absorption refrigeration; monomethylamine-water; food conservation.
