SUMMARY
Results of zonning of potential use of
ground source heat pump (GSHP) technology in the north
Vietnam
GSHP
(ground-source heat pump) heat exchangers with ground to provide durable
heating or cooling. Their technological feasibility and economic
viability depend on the nature of the ground heating and the suitability of the
area for the installation of the system. These parameters affect the geothermal
potential, which is defined as the heat energy that can be effectively
exchanged by a heat exchanger at a certain depth. We present a potential
partitioning method using ground source heat pump (GSHP) technology, which is
evaluated according to three main criteria: Criteria for cooling demand
according to regional climatic conditions; Criteria for composition
characteristics, thickness and thermal properties of soil cover; Criteria on
hydro-geological conditions.
This method
analyzes three criteria based on the ArcGIS platform to compare the maximum
aggregation of various factors related to the main criteria for shallow
geothermal assessment. give the rating. Using a hierarchical data analysis tool, suitable geographic
indicators to map the potential use of ground source heat pump technology in
the Northwest of Vietnam. As a first step, the authors divide the study
area into potentially advantageous areas, which are favorable for the use of
soil heat for air conditioning by GSHP technology.
Keywords: GSHP, potential zonning using GSHP.
