The
function
of
the
solar
circuit
The controller constantly compares the temperatures
between the collector (T1) and the lower area of the
storage tank (T
). Once the sun heats the collector and
there is a temperature difference of 8 K between the
collector and the storage tank, the pump is switched
on.
The pump extracts the heat transfer fluid from the
lower cooler area of the storage tank and pumps it to
the collector. The heat transfer fluid in the collector is
heated by the sun and flows back to the storage tank.
The heat transfer fluid heats the domestic water via a
heat exchanger located in the storage tank.
