| In a
solar collector exposed to the sun (a few
square meters), a black plate and metal tubes absorb solar
energy. |
|
The thermal sensor: It is the boiler of the solar
system!
If various types of solar collectors
exist, the glazed plane sensor is that used in the solar
kits.
The function of this sensor is to
convert the solar radiation into heat. |
A liquid
antifreeze circulating in the tubes is heated and
conveys the calories to the balloon of storage.
While crossing the heat exchanger,
within the balloon of storage, the liquid yields its heat to
domestic hot water. |
|
A coolant
(water glycolée in general) warms up while circulating in an
absorber placed under a glazing. In addition to its
orientation, the performance of the sensor depends on the
quality of the coating of the absorber and the glazing. It
is insulated thermically. Then, according to the desired use
(heating or hot water) and the complexity of the
installation, this fluid restores directly, or via an
exchanger, stored heat. |
