The panel is the energy source of the specially regulated heat pump, the energy coming from:
- Of the sun (thermal radiation)
- Thermal convection of the earth (ambient)
- Wind (heat exchange accelerator)
- Rain (heat dissipation contained in the water)
Is sucked through the heat exchanger
This is due to the temperature of the fluid (glycol) traveled in the exchanger which is permanently lower by a few degrees at room temperature.
As for the energy from the light radiation (sun), it allows to supply electricity to the compressor of the heat pump and the surplus can be self-consumed or resold.
A number of hybrid panel manufacturers (PVTs) use the photovoltaic panel and combine a heat exchanger on the back with insulation foam to prevent heat dissipation and prefer roof integration to further reduce this phenomenon. The panel on its thermal part operates in the same way as a solar thermal panel (continuous circulation of a coolant that will preheat a domestic hot water tank) This way of proceeding is in fact antinomic. Indeed, the photovoltaic panel works perfectly in bright light but on the other hand, the cells do not support heat (loss of power beyond 25 ° of surface temperature). This is why the glass is athermic treated, on the contrary, the efficiency of a thermal panel is determined by the ability to heat the integrated sensor (these panels rise to temperatures well above 100 °). The operating principle of Li-mithra hybrid panels is different. They can only be efficient if they are connected directly to a specially regulated heat pump. They are called Active and behave like "energy vacuum" and this, due to the coolant that travels through the exchanger and is colder than the ambient temperature. They work even without direct sunlight and ensure 100% of the heat needs (heating and domestic hot water) The Li-Mithra panel must be positioned over-stacked on the roof so that the heat exchanger under the panel can be swept by a blade of air and especially not be thermally insulated.
