6 FAQs about [What is the working fluid of solar collector ]
How do solar thermal collectors work?
However, in some cases, they are mounted on the ground. Solar thermal collectors come in two types: flat plate or excavated tubes. Heat transfer fluid – This is the fluid that moves the heat from the solar collector panel to the hot water tank. It can be anti-freeze, water or a mixture of the two.
How does a solar water system work?
In most domestic systems, the sun's heat energy increases the transfer fluid's temperature in the collector tubes. This fluid usually combines glycol (antifreeze) and water to prevent the water from freezing. The heated water from the solar collectors is then pumped to a heat exchanger, which is integrated into the water tank in the building.
