Thermosiphon solar system
Thermosiphon solar system Tube collectors are popular in the sense that they provide a little more efficiency during cloudy and colder days. The tubes are well insulated to retain the heat they absorb, but at the same time they are durable and long lasting. Another reason for their popularity is the indirect system in which they can function. The transfer fluid mix remains inside the collector, meaning there’s a more efficient heating process.
These systems have the least maintenance required as it uses natural hot and cold movement to circulate the water into the geyser above the collectors. Expected life span for a Thermosiphon system could be anywhere between 10 – 20 years, depending on the environmental conditions and water pressure consistencies.
Natural convection of the liquid starts when heat transfer to the liquid gives rise to a temperature difference from one side of the loop to the other. The phenomenon of thermal expansion means that a temperature difference will have a corresponding difference in density across the loop. The warmer fluid on one side of the loop is less dense and thus more buoyant than the cooler fluid on the other side. The warmer fluid will “float” above the cooler fluid, and the cooler fluid will “sink” below the warmer fluid. This phenomena of natural convection is known by the saying: “heat rises”. Convection moves the heated liquid upwards in the system as it is simultaneously replaced by cooler liquid returning by gravity
