Field tests and numerical simulation of a novel thermal response test equipment for water wells
Tanaka, Satoshi; Fujii, Hikari; Kosukegawa, Hiroyuki; Tsuya, Shunsuke (International Ground Source Heat Pump Association, 2022)The objective of this study is to develop a novel thermal response test (TRT) equipment that can be applied to existing water wells instead of borehole heat exchangers (BHEs). Accordingly, field tests were conducted using ... -
Numerical simulation of slinky-coil ground heat exchangers installed in railway tunnels
Fujii, Hikari; Taniguchi, Satoko; Ogai, Keisuke (International Ground Source Heat Pump Association, 2018)The use of horizontal ground heat exchangers (HGHEs) greatly reduces the initial cost of GSHP systems in comparison with vertical GHEs. Though the HGHEs are commonly used in North American countries, the installation number ... -
Potential mapping of ground source heat pump systems considering groundwater pumping
Fujii, Hikari; Yamashita, Kanako; Tsuya, Shunsuke; Kosukegawa, Hiroyuki (International Ground Source Heat Pump Association, 2022)The pumping of groundwater near GHEs improves the performance of GSHP systems due to the advection of the induced roundwater flow when the hydraulic conductivity of the formation is favorable. To quantify the effect, we ...
