“…In this context, geothermal heat pump (GHP) system has already turned into a dominant choice for energy supply in commercial and residential buildings owing to its high Coefficient of Performance (COP) [9]. The global GHP capacity is anticipated to increase by about 150% from 2013 to 2020 [10], as shown in Fig. 1.…”

“…1. World installed and predicted capacity of GHP units from 2013 to 2020 [10] In comparison to other traditional heating and cooling units, the GHP system has a lower operating cost and less influence on the atmosphere [11,12]. Soil temperature is normally lower than the ambient air temperature in cooling season, but higher in heating season.…”

Geothermal heat pump has been widely recognized as one of the promising technologies for building applications because of its high energy efficiency and low operating expense, however the high capital investment and installation costs discourage building owners to choose such a system. The horizontal geothermal heat pump system with reduced cost is a viable option that would be utilized widely, the aim of this paper is to catalogue and critique a range of effective approaches for the horizontal geothermal heat pump systems in different regions based on techno-economic assessment data. A ground heat exchanger is a vital component of the horizontal geothermal heat pump. The state-of-the-art analytical and numerical models of the linear-loop, slinky-coil and spiral-coil ground heat exchangers are generalized, in addition to their advantages and disadvantages. A large number of economic evaluation methods for analysing the financial performance of the horizontal geothermal heat pump system are presented. At the end, the standpoints, recommendations and potential future study on the horizontal geothermal heat pump system are deliberated.

“…There exist many studies on economic analysis of hybrid GSHPs, from simple techno-economical analysis (Seo et al 2018, Yousefi et al 2018) to more complex financial optimization approaches (Retkowski et al 2014, Henault et al 2016, Ikeda et al 2017, Kayaci et al 2018, Beckers et al 2018, Aditya et al 2020. Finding the optimal design of a hybrid GSHP system that minimizes the expected long-term cost while providing significant energy savings remains a complicated and computationally tedious task.…”

Feasibility of closed loop ground source heat pump for residential heating and cooling applications in Serbia

Households sector in Serbia presents a great chance for energy savings and introduction of RES in the future. The public policies in Serbia are currently limited, but this kind of study can influence public measures that would undeniably generate long-term social and economic benefits to the country. The aim of the present work is to assess economic feasibility of closed loop heat pump systems for heating and cooling purposes in Serbia's residential sector. The heat pump system was compared to the most commonly used heating fuels in households. Results indicate that the implementation of ground closed loop heat pump systems for heating and cooling purposes in Serbia's residential sector as a substitute for electric heating is economically feasible. Inadequate prices of natural gas and electricity in public supply are the main problems associated with the project's financial benefits. The best results were obtained in the scenario with combined debt ratio (40%) and grants (~30%) for the project realization, for which equity pay-back period is approximately three years, while benefit to cost ratio is 2.52. Investigated financial metrics (equity pay-back, internal rate of return assets and net present value) indicate the same positive results considering financial viability of the project.
