Geothermal heat pump

  1. 1. Hinako Osumi
  2. 2. Introduction Maintaining a comfortable indoor temperature can use up to half of your home’s energy. That means green technologies that can help reduce your heating and cooling bills will have some of the quicker returns on investment.
  3. 3. Explanation If you have central heating and air in your home, the way it maintains the temperature is by exchanging air inside of your house and with the air outside. In the summer, your HVAC unit pumps out hot air as it cools the air inside, and in the winter it takes heat from outside and transfers it into your home.
  4. 4. What is HVAC? Heating, Ventilation, and Air-Conditioning-three closely related fundamental functions found in homes, offices, and other building structures. Heating-significant in maintaining adequate room temp. during colder weather conditions. Ventilation-making sure that people are inhaling fresh air. AC-controls the heat as well as ventilation.
  5. 5. Geothermal Heat Pumps HVAC explained in the previous slide is not the most efficient system, since in summer the outside air is hotter than you want and in winter it’s usually much colder. A geothermal heat pump works the same way, but its heat exchange apparatus is buried underground, where temperatures are a lot more stable. Geothermal heat pumps are among the most efficient and comfortable heating and cooling technologies currently available, because they use the earth’s natural heat to provide heating, cooling, and often, water heating.
  6. 6. More Advantages Efficiency: Geothermal heat pump can might cost you more in the beginning for installation, but it can reduce your heating and cooling costs by as much as 30 to 40 percent. Speed: It works a lot quieter than a conventional HVAC system. Durability: Lasts longer than HVAC.
  7. 7. How Can It Solve Current GlobalIssues? This system does not consume tons of energies compared to ordinal HVAC units. The system lasts longer and does not expose any toxic material into the Earth’s atmosphere.
  8. 8. Comments “it definitely has potential, but the systems are still not well understood by the general public, causing a backlash when they encounter the trade-offs” “my geothermal system doesn’t save me as much money as I thought” “I’m always having trouble with it”
