Abstract:
This study presents an evaluation of the performance of an electric vapor compression solar refrigeration system coupled with solar energies for the different climatic zones in Madagascar. For the 5 selected cities, a building of the same constructive design was used. Hourly building heat loads were estimated from the heat balance method using meteorological data from selected cities such as hourly average solar radiation and atmospheric temperatures. Then, the hourly evaluation of various parameters such as the coefficient of performance, the capacity of the condenser, the electrical consumption of the compressor and the power of the photovoltaic generators as well as its surface for different evaporation temperatures were determined. It was determined that the SE-VCR system could be used successfully for the province of Mahajanga, Antsiranana, Toliara and Tamatave while for the city of Antananarivo was not very interesting.For these 4 cities, the coefficient of performance varies from around 3.3 to 4.43 for an evaporation temperature Te = 0 ° C. And the power of the compressor varies from 5.66 to 7.5 kW with a peak power of the solar panels varying from 21.16 to 25.23 kWp with a respective surface of 104.93 to 125.12 m². The overall efficiency of the installation varies from 0.483 to 0.521.
