Cooling Thermal System Using Solar Energy

Solar thermal collectors are classified by the united states energy information administration as low medium or high temperature collectors.

Cooling thermal system using solar energy.

In solar cooling systems solar thermal heat is used as the driving force behind the cooling process. Thermal energy can be generated from many renewable sources such as solar biomass and geothermal. Solar heating cooling shc technologies collect the thermal energy from the sun and use this heat to provide hot water space heating cooling and pool heating for residential commercial and industrial applications. Thermally driven cooling machines such as ab or ad sorption chillers have been used for many decades.

A typical solar cooling system also provides space heating and hot water besides cooling. Low temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. If the solar system cannot provide adequate space heating an auxiliary or back up system provides the additional heat. Cooling with solar thermal as paradoxical as it may seem cooling using solar energy is feasible using solar thermal energy.

These systems are known collectively as renewable heating and cooling technologies. These technologies displace the need to use electricity or natural gas. 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. The diagram below shows the typical vapor compression cycle supported by a solar thermal panel.

When the sun is at its hottest solar irradiation is high the maximum energy is available and the demand is also high. Solar chillers use thermal energy provided by the sun or other backup sources to produce cold and or dehumidification. One of the main require ments of such systems is to have an effective. 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.

Solar refrigeration technologies harness the energy of the sun and use it to run a cooling system. The solar cooling supply is equal to the demand.
