Development Of Geothermal Heating And Cooling

By:


Currently, many countries in the world give considerable attention on geothermal energy for district heating or we called geothermal heating. This is because many countries in the world concerns in the use of renewable energy. This was triggered by the higher world oil prices and therefore it will contribute to economic activity. Moreover the use of renewable energy will reduce emission in environmental.

During this time many successful projects making geothermal heating district is reported. The experience of researchers and engineers still play an important role in the design and control as well as developing geothermal heating systems for district system.

Some researchers like Lund and Freeston have reviewed the application of geothermal energy for direct use. They reported that that estimating of geothermal energy use in early 2000 is 190,699 TJ/year or 2,972 GWh / yr.

Thermal energy used for several of categories as follows

42% geothermal heating for bathroom and swimming pools
23% for space heating or 42 926 TJ / year
12% for geothermal pump
9% for greenhouse heating
6% for aquaculture pond and raceway heating
5% for industrial applications
2% geothermal heating for other uses
less than 1% of each farm drying, melting snow and air conditioning.


Growth in energy use for space heating since 1995 grew by 12%, or 2.3% per year. As reported by Hepbasli and Canakcib, About 75% of the 42,926 TJ/yr utilization for space heating is estimated for district heating and the remainder for individual space heating.

Most of district heating system was in Europe where France and Iceland as a leader for this system. United States, on the other hand, dominates the heating system to individual homes like in Klamath Falls, Oregon, and Reno, Nevada. Other countries that are extensive develop district heating system are China, Japan and Turkey. Turkey has a 12:10% in the use of heat energy in the world.
