CCOP-GSJ Groundwater and Ground-Source Heat Pump (GSHP) Project

JICA’s SDGs Business Model Formation Survey with the Private Sector: Energy-saving Cooling System using Groundwater Heat Source Pump
Duration: 2019 - 2022 (On-going); The previous phases of the project include: Phase I (2005 ~ 2008); Phase II (2009 ~ 2014); & Phase III (2015 ~ 2019).
Funding Source: Geological Survey of Japan (GSJ), AIST, in cooperation with JICA and Misawa Enviromental Technology Co., Ltd. (MISAWA)
Participants of CCOP-DMR-MISAWA-GSJ Workshop for Application of Groundwater Heat Source, 5 November 2019, Chiang Mai, Thailand.
Project Summary / Brief Description
GSJ has worked on this GSHP project in the region for many years. The subproject entitled “Development of Renewable Energy for Ground-Source Heat Pump (GSHP) System in the CCOP Regions” started under the CCOP Groundwater Project in April 2013. The subproject utilizes the groundwater temperature data in the CCOP Hydrogeological map. In the subproject, the first GSHP System was installed at the premise of Chulalongkorn University, Thailand under the cooperation between Chulalongkorn University, Akita University and GSJ, then at the premises of Golden Jubilee National Geological Museum, Pathum Thani and Vietnam Institute of Geoscience and Mineral Resource (VIGMR) to estimate the system performance with long term experiments.
GSHPs are recognized as environmentally friendly cooling and heating systems due to their higher energy efficiency than air source heat pumps (ASHPs). Also, the heat disposal into the ground during cooling operations can mitigate the urban heat island phenomena. Hence, the wide application of GSHPs is considered as one of the most effective measures against the global warming.
The latest development is the joint partnership with Japanese private sector among GSJ, JICA, and MISAWA company in 2019 in to conduct the feasibility survey (year 1) and the verification survey (year 2-4) to verify the usefulness of selected Japanese products and technologies through actual installation and operation of products to be handed over the counterpart organization upon completion of the survey, i.e, National Geological Museum (DMR), Thailand.
Goals/Objectives
  • To introduce energy-saving cooling system that utilizes groundwater heat source instead of traditional air conditioners using air-source heat pump in the Capital Region of Bangkok.
  • To confirm whether the system introduced can reduce electricity consumption, contribute to improve heat island phenomena, and mitigate global warming.


Scope of the Survey
  • Formulation survey of the business model is conducted with DMR and DGR.
  • Boring test and thermal response test at the National Geological Museum of DMR in Pathum Thani are carried out to understand hydrogeology and thermal property.
  • Indoor cooling condition in Bangkok is surveyed and the adaptability of the cooling system is confirmed.
  • Business development plan and promotion plan are also formulated based on the market evaluation through the survey on cooling condition of large commercial facilities and others.


Outcome
  • SDGs Business Verification Survey with the Private Sector.
