<p>The heat emission and diffusion system uses a closed hydraulic circuit comprising an air-to-water heat exchanger, a circulating pump, a heat exchanger buried in the ground, and a third heat exchanger connected to a circuit utilising the heat or refrigerating action. The air is blown over the air-to-water heat exchanger by a fan controlled by a differential unit. The latter has a first probe to probe sensing the ambient air temp.</p> |
