2022 Research Conference Proceedings, International Ground Source Heat Pump Association
Spitler, Jeffrey D.; Acuna, Jose; Bernier, Michel; Cimmino, Massimo; Fang, Zhaohong; Gehlin, Signhild; Javed, Saqib; Liu, Xiaobing; Rees, Simon; Stumpf, Andrew; IGSHPA Research Track (2022) (International Ground Source Heat Pump Association, 2022) -
Development of a topology optimization method for the design of ground heat exchangers
Noel, Alexandre; Cimmino, Massimo (International Ground Source Heat Pump Association, 2022)A new method for sizing vertical ground heat exchangers is proposed using topology optimization to reduce the number of boreholes required to fulfill the cooling and heating demand. The ASHRAE sizing equation is adapted ... -
Examination of ambient temperature variations effects on predicted fluid temperatures in vertical boreholes
Cimmino, Massimo (International Ground Source Heat Pump Association, 2017)A fully-coupled model of geothermal bore fields is presented, taking into account the axial variations of borehole wall temperatures and heat extraction rates along the borehole lengths, fluid temperature variations inside ... -
Heat pump capacity effects on peak electricity consumption and total length of self- and solar-assisted shallow ground heat exchanger networks
Eslami Nejad, Parham; Cimmino, Massimo; Hosatte-Ducassy, Sophie (International Ground Source Heat Pump Association, 2017)A new "self-assisted" Ground Source Heat Pump (GSHP) system configuration is proposed to address the relatively high peak electricity demand of undersized GSHP systems equipped with auxiliary electric heater. In this ... -
pygfunction 2.2 : New features and improvements in accuracy and computational efficiency
Cimmino, Massimo; Cook, Jonathan C. (International Ground Source Heat Pump Association, 2022)Recent improvements to pygfunction, an open-source tool for the calculation of ??-functions, are presented. The latest version 2.2 enables the calculation of ??-functions for fields containing inclined boreholes. Various ... -
Transient heat transfer in ground heat exchangers under groundwater flow
Prieto, Carlos; Cimmino, Massimo (International Ground Source Heat Pump Association, 2022)An analytical solution for the transient heat transfer under groundwater flow for ground heat exchangers (GHEs) is presented. The method is an extension of the transient multipole expansion that describes the transient ...
