Conclusions
From this study, the conclusions are as follows:
1. The geothermal energy potential at around 6.6 MW could be
developed in Thailand by 4 technologies which are organic rankine
cycle for generating electricity, absorption chiller for cooling
process, central drying room for heating process and drying room
integrating with vapor compression heat pump for boosting heat
process.
2. For the ORC technique, 12 high potential hot springs could be
generated electricity from the surface heat and the reservoir heat are
around 512 kWe and 3,909 kWe, respectively.
3. Absorption chiller and 8 moderate potential hot springs could be
produced the total cooling capacity around 304 kW and the payback
period of absorption chiller is 22 months.
4. Central drying room and 8 moderate potential hot springs could be
used in the heating process at the total capacity around 406 kW and
the payback period of the central drying room is 15 months.
5. For the boosting technique, 26 hot springs could be upgrading
heat around 2,002 kW by using the drying room integrating with
the vapor compression heat pump and the payback period of this
method around 29 months.
