Refrigeration systems that use environment-friendly refrigerants provide a sustainability advantage when compared to other refrigerant selections.using solar as the primary energy source is attractive prospect because of its universal availability, low environmental impact, and low or no ongoing fuel cost.three approaches that use solar energy to provide
refrigeration at temperatures below 0°C (32°F) are discussed below:

Vapor Compression Refrigeration
In the vapor compression cycle, cooling is provided in the
evaporator as low temperature refrigerant entering the evaporator
as a mixture of liquid and vapor at State 4 is vaporized by
thermal input from the load. The remaining equipment in the
system reclaims the refrigerant and restores it to a condition
in which it can be used again to provide cooling. The major energy input to a vapor compression refrigeration system is the mechanical power needed to drive the compressor.Two of the solar refrigeration systems considered here rely on the vapor compression refrigeration cycle in some form. The third solar refrigeration system uses thermal energy as the
primary input to the cycle. Open cycle systems that use water
as the refrigerant, such as the solar desiccant cycle, could be
used to provide cooling at temperatures above freezing

Photovoltaic Operated Refrigeration Cycle
Photovoltaics (PV) involve the direct conversion of solar
radiation to direct current (dc) electricity using semiconducting
materials. In a simple implementation one would expext, the Solar photovoltaic panels produce dc electrical power that can be used to operate a dc motor, which is coupled to the compressor of a vapor compression. to operate at high effi ciency, it is essential that the voltage
imposed on the PV array be close to the voltage that provides
maximum power.One solution to this is a maximum
power tracker can be used which, in effect, continuously
transforms the voltage required by the load to the maximum
power voltage.

Solar Mechanical Refrigeration
It uses a conventional vapor
compression system driven by mechanical power that is produced
with a solar-driven heat power cycle.a Rankine cycle is the best suited cycle.in this a fluid is vaporized at an elevated pressure by heat exchange with a fl uid heated by solar collectors refrigeration system.
