Title:         Towards utilization of energy efficient ground source heat pump in tropical country
Authors:    Arif Widiatmojo
Abstract:   Space heating and cooling by using Ground Coupled Heat Exchanger, known as Ground Source Heat Pump (GSHP) is one of the direct utilization of Geothermal resources. It has been used in many countries, especially in four season countries to fulfil both heating and cooling demand. The GSHP system taking advantages of constant underground temperature throughout the years and could significantly reduce the electricity consumption compared to those normal Air Conditioning (Air Source Heat Pump, ASHP). Despite its potential, there are several factors that hinder the utilization of Ground Source Heat Pump in many countries, especially in tropical countries. For example, social barriers such as lack of information regarding GSHP technology. Technical barriers include lack of information, technical barrier such as high initial cost, lack of data regarding the utilization of GSHP in tropical countries, unknown technical uncertainties, etc. To provide technical information of GSHP utilization in tropical countries, various data analyses are currently being carried out considering data from installed GSHP system in Thailand and Vietnam. The analyses cover various technical factors, such as, long term performances, potential power consumption reduction, effect of local and regional groundwater system as well as optimization of horizontal and vertical heat exchanger configurations.
