As the fluid has a boiling temperature of approximately -30C , the system works even when there is no sun and it even works at night, hail, rain, wind or shine , unlike the traditional solar thermal system .
The energy consumption of the system is basically the same as fridge compressor that makes the liquid circulate. there are no ventilators that help the evaporation process, of defrost cycles, which imply unnecessary energy consumption, unlike what happened with heat pump
