Abstract
First trial on Geo-heat pump application for tropical land was carried out at Kamphamgpet (Central Thailand) in 2006 and moved to Bangkok in 2010. Underground temperature of Thailand is 5-10oC lower than atmospheric one. Even though, we get 20-40% energy shortage than normal electric air condition. Bangkok system is designed for space cooling by using 1m depth horizontal piping line. Our experiment is less than one year but the system is working well. The COP (coefficient of performance) is 3-4 and underground temperature is recovered quickly. Shallow horizontal system is the best for tropical countries because temperature is the lowest and construction cost is low. We continue to operate more longer term and finding best system and operation method of GHP in tropical land.
