Solar Still:
A solar pond is a type of solar energy system that utilizes a large, shallow body of water to capture and store solar energy. The working principle of a solar pond involves several layers and processes. Here's a general overview:
Construction: A solar pond is constructed by creating layers of water with different salinity levels. The pond is typically lined with a dark-colored material, such as black polyethylene, to absorb sunlight effectively.
Three-Zone Structure: A solar pond is divided into three distinct zones or layers:
a. Upper Convective Zone (UCZ): This is the top layer of the pond, usually a few centimeters to a meter deep. It contains low-salinity water that acts as a solar energy absorber.
b. Non-Convective Zone (NCZ): The NCZ is the middle layer of the pond, ranging from a few meters to tens of meters in depth. It contains highly concentrated saltwater, which helps trap the absorbed solar energy in the UCZ, preventing it from escaping through convection.
c. Lower Convective Zone (LCZ): The LCZ is the bottom layer of the pond, consisting of denser, higher-salinity water. It acts as an insulating layer, preventing the transfer of heat from the NCZ to the deeper layers.
Solar Energy Absorption: Sunlight penetrates the transparent cover of the pond and reaches the UCZ. The dark-colored lining absorbs the solar energy and heats up the water in the UCZ.
Thermal Storage: The heated water in the UCZ transfers its thermal energy to the NCZ through conduction. The highly concentrated saltwater in the NCZ traps the thermal energy and prevents its dissipation, effectively storing the heat energy.
Heat Extraction: Heat can be extracted from the solar pond for various purposes, such as space heating or electricity generation. Heat exchangers or heat transfer systems are used to extract the thermal energy from the NCZ. The heat can be used directly or converted into other forms of energy.
The solar pond system works by capturing and storing solar energy in the form of heat within the NCZ. The salinity gradient and insulation layers help maintain the heat storage and prevent heat loss. Solar ponds are particularly useful in applications that require continuous or long-duration heat supply, such as in industrial processes, greenhouse heating, or desalination.
It's important to note that solar pond systems require careful design and management to optimize heat absorption and storage. Factors such as pond size, salinity levels, and solar radiation must be considered to maximize energy capture and efficiency.
