What is the difference between these two renewable energy air conditioning systems?

A ground-source heat pump is not a form of geothermal energy at all.

Geothermal:

  1. energy source is underground natural nuclear reactions;
  2. source temperature is over 50°C;
  3. Energy is extracted with passive heat exchangers.

Ground-source heat pumps:

  1. energy source is solar radiation;
  2. source temperature is about the same as annual average air temperature;
  3. Energy is extracted using active technology, compressing and expanding fluids to lift the temperatures to something useful.
  • I see. Ground-source heat pump is not exactly a form of Geothermal energy – Needa Hell Nov 18 '15 at 7:50

  • So the geothermal heat pump refers to geothermal energy? – Needa Hell Nov 18 '15 at 8:05
  • Can you give a specific example of a "geothermal heat pump"? – EnergyNumbers Nov 18 '15 at 8:06
