Simplified tools and design guidelines for solar cooling systems are still missing. Within ZEOSOL, components for a solar cooling system were experimentally characterized. Experimental activity was focused on the proper integration and control strategy. A seasonal EER higher than 15 and a Thermal COP of 0.55 are expected.
4.1. Generalities Usually, the sizing of a solar cooling system is accomplished using dynamic modelling tools, able to follow the variation of the sun and therefore of the solar yield. A typical example, as already reported in the literature analysis, is the use of TRNSYS.
As with solar heating, the techniques for solar cooling consist of passive systems and active systems. The passive systems are not part of this course. For active solar cooling systems the three most promising approaches are the heat actuated absorption machines, the Rankine cycle heat engine, and the desiccant dehumidification systems.
For active solar cooling systems the three most promising approaches are the heat actuated absorption machines, the Rankine cycle heat engine, and the desiccant dehumidification systems. A brief summary of these systems is given here and a more detailed explanation can be found in other sources in the literature. 2. ABSORPTION COOLING.
The tracking system helps to increase the current generation by continuously tracking the sun angle and voltage can be increased by controlling the temperature with the aid of a cooling system. Thus, the power generated by solar PV system and the overall efficiency are improved by mechanical tracing and cooling of solar panel.
