HEAT PUMP SYSTEMS
A heat pump is a highly efficient and environmentally friendly heating and cooling system that transfers heat from an external source (air, water, or ground) to the interior of buildings.
It uses electricity to circulate a refrigerant, producing up to five times more thermal energy than consumed, ideal for winter heating, summer cooling, and domestic hot water production.
Here are the key details about the heat pump:
How it works: It uses a refrigeration cycle (evaporation, compression, condensation, and expansion) similar to a refrigerator, but in reverse, extracting heat from the outside and bringing it inside.
Advantages:
Significantly reduces energy consumption and polluting emissions compared to gas boilers, especially when powered by photovoltaic systems.
Common types:
Air-to-air: Uses outside air to heat/cool indoor air (like air conditioners).
Air-to-water: Uses outside air to heat the system's water (radiators or radiant panels).
Geothermal (water/ground-to-water): Uses heat from the ground or aquifers, offering even higher efficiency.
Efficiency: Measured by the COP (Coefficient of Performance) for heating and the EER (Energy Efficiency Ratio) for cooling.
