ART. S001-S002-S003-S004 SOLAR MODULE
PRINCIPLE OF OPERATION
ICMA solar modules art. S001-S002-S003-S004, as already
written above, are employed in the primary circuits of solar
systems to manage the thermodynamic cycle of the heat-transfer
fluid between the solar panels and the hot water storage tank.
In thermal solar panels the solar radiation increases the heat-
transfer fluid temperature and therefore its thermal power.
In the storage tank, instead, the heat-transfer fluid carries through a
heat exchanger most of its heat to the water in the tank.
The hot water in the tank will be then used for space heating or
domestic use.
The solar modules manage this process and are equipped with a
circulator pump having proper performances (flow and head) as
well as several regulation and control devices that run the operation
of the circuit.
