Heat pump capacity effects on peak electricity consumption and total length of self- and solar-assisted shallow ground heat exchanger networks
(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 ...
Model for ground temperature estimations and its impact on horizontal ground heat exchanger design
(International Ground Source Heat Pump Association, 2017)
The ground-source heat pump systems are highly efficient and energy saving. Its main disadvantage is a significantly higher installation cost compared to conventional systems. The length of the ground heat exchanger (GHX) ...
Development of TPRT (Thermal Performance-Response Test) for borehole heat exchanger design
(International Ground Source Heat Pump Association, 2017)
To obtain the effective thermal conductivity and borehole thermal resistance required to design borehole heat exchangers (BHEs), thermal response tests (TRTs) are usually conducted. Although many advanced TRT methods have ...
Development of polyolefin compound and post-polymerization treatments for ground heat exchangers
(International Ground Source Heat Pump Association, 2017)
A ground source heat pump (GSHP) system can be used for both cooling and heating modes simultaneously for commercial, industrial and residential buildings virtually at any location with great flexibility to cover a wide ...
Second-order multipole formulas for thermal resistance of single U-tube borehole heat exchangers
(International Ground Source Heat Pump Association, 2017)
The borehole thermal resistance is both an important design parameter and a key performance characteristic of a borehole heat exchanger. Another quantity that is particularly important for deep borehole heat exchangers is ...
Modelling and experimental validation of a novel co-axial spiral borehole heat exchanger
(International Ground Source Heat Pump Association, 2017)
In order to optimize the operation of a ground source heat pump (GSHP) system, the development of dynamic models that integrate all the system components is a key factor. Particularly, the modelling of the ground source ...
