Outline of Final Research Achievements

Geo-heat pump system using horizontal thermal coupling and modified air conditioner are operating at Bandung Institute Technology, Indonesia. This system attains 25% shortage of electricity. Underground temperature is almost stable which grantee for long term good operation.
Facilities and technique are all prepared at Indonesia. Then the cost of system becomes less than 1/10 for conventional cost. It is very hopeful result to keep earth environment good for introduction of this system to tropical countries where power consumption for cooling is very big.
