Unveiling the Solar Water Heating System Technology

Solar Water Heating System

The solar radiation occurrence on the surface of the earth can be helpfully used for the advantage of human culture. One of the prevalent gadgets that outfit the solar vitality is solar hot water system (SHWS).

Sunlight based water heater comprises of a collector to collect solar energy and a protected/insulated stockpiling tank to store hot water. The solar energy occurrence on the sunrays absorber panels coated with selected coating brings the hat to the riser pipes underneath the absorber panel. The water going through the risers get heated up and supplied to the storage tank. The re-circulation of the same water through absorber panel in the collector raises the temperature to 800C(Max) in a bright sunny day.

The aggregate framework with solar collector, stockpiling tank and pipelines is called solar hot water system (SHWS).

The two classes of the solar hot water systems: Closed loop framework and open loop framework.

In the closed loop, heat exchangers are introduced to shield the system from hard water acquired from bore wells or from solidifying temperatures in the cold regions.

The other type, either thermo syphon or force circulation framework, the water in the framework is open in the climate at one point or other.

thermo syphon frameworks

The thermo syphon frameworks are simple and economical. They are suitable for domestic and small institutional frameworks, provided water is treated and consumable in quality. The forced circulation frameworks utilize electrical pumps to circulate the water through collectors and capacity tanks. The choice of framework relies on upon heat prerequisite, climate conditions, heat exchange fluid quality, space accessibility, annual solar radiation, and etc.

The SHW frameworks are economical, contamination free and simple for operation in warm nations such as our own.

The next article will describe on the different types and salient features of SHWS.
