2. HOW SOLAR REFRIGERATION UNITS WORK

Solar refrigeration units typically operate through two main mechanisms: photovoltaic systems and solar thermal systems.

PHOTOVOLTAIC SYSTEMS EXPLAINED

Photovoltaic (PV) systems harness solar energy by converting sunlight directly into electricity through solar panels. These panels are installed on rooftops or other structures to capture maximum sunlight exposure. The electricity generated powers the refrigeration unit, making it possible to operate without drawing from the grid. This setup allows flexibility in installation, making it ideal for both residential and commercial applications.

In essence, when sunlight strikes the solar panels, it excites electrons within the PV cells, producing a flow of electricity. This direct current (DC) electricity is then converted to alternating current (AC) electricity with the help of an inverter, enabling the refrigeration unit to function efficiently. The ability to store energy in batteries when there is abundant sunlight further enhances the reliability of PV systems, ensuring that cooling is maintained even during cloudy days or at night.

SOLAR THERMAL SYSTEMS EXPLAINED

Solar thermal systems, on the other hand, utilize sunlight to heat a fluid that can then generate power. In this scenario, a system of mirrors or lenses concentrates sunlight onto a receiver, where the heat is absorbed by a working fluid such as water or oil. The heated fluid can either be used directly in a heat-driven refrigeration cycle or converted into mechanical energy for an electric refrigeration unit.

This approach capitalizes on the principles of thermodynamics, where heat absorption can induce cooling. Solar thermal refrigeration presents a promising alternative, particularly for large-scale applications or industrial settings. It integrates seamlessly with existing cooling infrastructures, offering a remarkable way to cut energy costs while enhancing environmental sustainability.
