It is concluded that there is no advantage in decreasing the area of the condenser (except a slight PTK787 in the overall weight of the solar refrigerator); however, it is interesting to note that the reduction of area to 5 m2 still allows reasonable operation of the installation, since the COP is maintained above 0.06. This means that it is possible to build a more compact, lighter and cheaper solar refrigerator without a large decrease on performance.
