“…Studies on GCHPs applications in European [17][18][19][20][21], American [22,23] and Asian climates [24,25] have been performed, in single residential or office building cases. Analyses of economic feasibility and environmental benefits for residential buildings were carried out by Lu et al [26], Morrone et al [27], and Chang et al [28]. Ciulla et al [29] estimated the thermal energy demand for the office building typology in different European climates.…”

Ground-coupled heat pumps (GCHPs) have a great potential for reducing the cost and climate change impact of building heating, cooling, and domestic hot water (DHW). The high installation cost is a major barrier to their diffusion but, under certain conditions (climate, building use, alternative fuels, etc.), the investment can be profitable in the long term. We present a comprehensive modeling study on GCHPs, performed with the dynamic energy simulation software TRNSYS, reproducing the operating conditions of three building types (residential, office, and hotel), with two insulation levels of the building envelope (poor/good), with the climate conditions of six European cities. Simulation results highlight the driving variables for heating/cooling peak loads and yearly demand, which are the input to assess economic performance and environmental benefits of GCHPs. We found that, in Italy, GCHPs are able to reduce CO 2 emissions up to 216 g CO 2 /year per euro spent. However, payback times are still quite high, i.e., from 8 to 20 years. This performance can be improved by changing taxation on gas and electricity and using hybrid systems, adding a fossil-fuel boiler to cover peak heating loads, thus reducing the overall installation cost compared to full-load sized GCHP systems.

“…Yuan et al [7] reviewed the analytical solution, numerical solution and experimental investigation of the heat transfer of GHE, and the paper also analyzed the simulation model and long-term operation performance of the GSHP system. Other papers focus on the thermodynamic, economic and energy analysis of GSHP system [9][10][11]. For instance, Menberg et al [10] studied a detailed thermodynamic analysis of individual components of a hybrid GSHP system.…”

Experimental analysis of a continuous operating ground source heat pump system in Wuhan, China

Coefficient of performance of air conditioning system is the ratio of cooling capacity and power consumption, and also is an important parameter to characterize the performance of the system. Based on an actual ground source heat pump system in Wuhan, China, this paper calculated the coefficient of performance of the system under long-term continuous cooling operation and then evaluated the performance of the system through experiment. The continuous testing time ranged from June 1, 2017, to June 15, 2017, and the outside air temperature ranged from 21 °C to 32 °C during the testing progress. The experimental results show that the coefficient of performance of the system changes non-linearly with time, and varies greatly with the atmospheric temperature. The results also show that the coefficient of performances average value of the system is about 3.3, and the system has good performance under refrigeration conditions. This paper helps to understand the changes in the distribution characteristics of the coefficient of performance of the ground source heat pump system and promote the wide application of the ground source heat pump system.

“…These parameters are based on the work by Lu et al (2017) and are shown in Table 3. In particular, it has been assumed that the life spans of GSHP systems are 20 years.…”

“…Despite their efficiencies, property owners find it difficult to adopt GSHP systems due to their higher upfront costs and longer payback periods (Karytsas and Choropanitis, 2017;Lu et al, 2017). One strategy to reduce these costs and payback periods is to utilise hybrid ground source heat pump (HGSHP) systems, whereby GSHPs provide the baseload thermal energy to buildings with the balance provided by other, usually conventional, systems during particularly hot and cold periods of the year.…”

“…For example, GSHP systems have been reported to have a CoP between 3 to 5 (Bloom and Tinjum, 2016;Liu and Spitler, 2014;Lu et al, 2017;Michopoulos et al, 2007;Trillat-Berdal et al, 2006). Conventional heating and cooling systems, such as a reverse cycle air conditioners (RCAC, Air Source Heat Pump Systems), typically have a CoP of 2 to 4 (Huang, 2015;Liu and Spitler, 2014;Lu et al, 2017;Self et al, 2013;Wu, 2009). Other conventional systems which use electricity and gas to provide heating operate at a CoP of less than 1 and unable to provide cooling.…”
