When calculating the heat flow in the primary and secondary system, it is important to account for the energy that is lost along the pipes from the solar collectors to the consumption points, to optimize the sizing of the collection area, which is required to also compensate for that loss of energy.
Up to the 2021.a version, users could contemplate, in a simplified way, the energy that is lost along the length of the pipes from the solar collectors to the accumulators or heat exchangers (primary circuit) and from these to the consumption points (secondary circuit), by considering a global loss coefficient of the circuit or by reducing the performance factor of the circuit.
As of the 2021.a version, "CYPEPLUMBING Solar Systems" calculates the energy loss in these circuits by analysing the path of the pipes and bearing in mind the material, thickness and insulation of these pipes, as well as factors such as temperature, and the discharge and return flow that circulates along them.
