Cooling Thermal System Using Solar Energy

A solar thermal cooling system uses solar energy to reduce the electricity needed for the process.

Cooling thermal system using solar energy. Solar chillers use thermal energy provided by the sun or other backup sources to produce cold and or dehumidification. Solar thermal collectors are classified by the united states energy information administration as low medium or high temperature collectors. Solar refrigeration technologies harness the energy of the sun and use it to run a cooling system. These systems are known collectively as renewable heating and cooling technologies.

Active solar heating systems use solar energy to heat a fluid either liquid or air and then transfer the solar heat directly to the interior space or to a storage system for later use. One of the main require ments of such systems is to have an effective. The thermal collection unit is installed on the discharge side hot gas side of the compressor. In solar cooling systems solar thermal heat is used as the driving force behind the cooling process.

Low temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. The diagram below shows the typical vapor compression cycle supported by a solar thermal panel. Thermally driven cooling machines such as ab or ad sorption chillers have been used for many decades. This type of solar application is an attractive option for the preservation of food and the refrigeration of vaccines and medicines in areas with a high intensity of solar radiation and no electricity supply.

When the sun is at its hottest solar irradiation is high the maximum energy is available and the demand is also high. A typical solar cooling system also provides space heating and hot water besides cooling. Cooling with solar thermal as paradoxical as it may seem cooling using solar energy is feasible using solar thermal energy. The solar cooling supply is equal to the demand.

If the solar system cannot provide adequate space heating an auxiliary or back up system provides the additional heat. These technologies displace the need to use electricity or natural gas.
