Refrigeración solar por adsorción con sistema de captación CPCexperimentos y modelo

Resumo

A prototype of solid sorption solar chiller using the activated carbon / methanol couple has been designed and built. Its major features are: - A novel design of compound parabolic concentrator (CPC), allowing a good compromise between daily collection of radiation and an efficient nightly cooling of the reactor. - Water-cooled shell-and-tubes condenser, the cooling water coming from a water tank annex to the unit. - A continuous experimental record of the methanol concentration in the reactor, which permits a detailed analysis of the thermal exchanges in all the parts of the unit. The prototype was experimentally tested, and the average COP was 0.09. A mathematical model to simulate the operation of the unit has been implemented. This model is helpful to forecast the unit performance under a variety of environmental conditions, and as a result of a change in design parameters
