It is the refrigeration system that runs on the solar energy where the power is supplied not by the electrical supply system, but from the solar panel. In this process we produce refrigeration effect with the help of energy of sun and thermal energy or photovoltaic may be included in this.
Solar absorption refrigeration systems can be integrated with existing cooling systems, such as traditional vapor-compression systems, to enhance efficiency and provide backup cooling capacity during periods of low solar irradiance or high cooling demand.
In the absorption refrigeration cycle, a solar double product system was proposed . Through the proposed system with matched system output, the energy saving achieved was 25.64%. The proposed system had an external energy efficiency of 9.83%, which was 2.97% higher than the reference systems.
Solar photovoltaic panels produce refrigeration system. The major considerations in designing PV array. 25°C (77°F). Unfortunately, PV modules will operate over a ing condition. In addition, the power produced b y a PV array is as variable as the solar resource from which it is derived. The on the solar radiation and module temperature.
Solar aided refrigeration system can represent a simple and feasible solution for improving the sustainability of refrigerated transport. The paper presents the design and the performance of an electric powered refrigeration unit integrated with photovoltaic generators installed on top of the refrigerated box of a light truck.
Refrigeration system integrated with photovoltaic generators: (a) photovoltaic panels; (b) charge regulator; (c) on–off thermostat; (d) compressor; (e) battery pack; (f) backup line connected to the vehicle alternator. The refrigeration unit compressor (d) and fans are powered by the 24 V battery pack.
