It should be noted that various geothermal HVAC systems have been used in the world for more than 60 years. They work in harmony with nature, do not emit greenhouse gases, use less electricity to work, etc. And most experts predict that next year for green construction around the world will be spent 3-4 times more funds and occupy about 40% of the entire real estate market! But even though geothermal systems used in the heating, ventilation and thermal regulation industry are an integral part of such eco-friendly construction, a considerable amount of information is based on outdated data or even misconceptions.
Let’s consider some of them.
- The HVAC geothermal systems use only one unit of electricity to move (as already indicated) up to five cooling units or heating from the ground to the building.
- Photovoltaic energy and wind energy are more favorable renewable technologies in comparison with the HVAC geothermal systems.
The HVAC geothermal systems carry four times the kilowatt-hour of electricity consumption for the spent cut compared to photovoltaic or wind energy. Of course, these energies play a critical role in energy-efficient construction, but they are not uniquely the best way to reduce the impact on the environment through the conditioning of different zones. It should be remembered that water always returns after passing the heat exchanger, so it can not be said that it is being used and discharged, or there is any negative impact.
