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.

There are two main solar cooling processes. Cooling with solar thermal as paradoxical as it may seem cooling using solar energy is feasible using solar thermal energy. The thermal collection unit is installed on the discharge side hot gas side of the compressor. 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. Low temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. 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.

Thermally driven cooling machines such as ab or ad sorption chillers have been used for many decades. 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. When the sun is at its hottest solar irradiation is high the maximum energy is available and the demand is also high.

The diagram below shows the typical vapor compression cycle supported by a solar thermal panel. 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. A typical solar cooling system also provides space heating and hot water besides cooling. If the solar system cannot provide adequate space heating an auxiliary or back up system provides the additional heat.

Thermal energy can be generated from many renewable sources such as solar biomass and geothermal. A solar thermal cooling system uses solar energy to reduce the electricity needed for the process.
