The Hybrid Ground Source Heat Pump (GSHP) system features the combination of ground heat exchanger (GHE) and cooling tower for rejecting the cooling load, which enables the use of the renewable resource of geothermal energy while reducing the cost of installation for applications of high cooling demand. However, model based control for efficient operation of the GSHP system can be intricate due...

In recent years, the medium-depth ground source heat pump (MD-GSHP) has become a promising and potential geothermal energy heating technology. This is due to superior characteristics of buried pipes with small diameter, high efficiency pump, insensitivity climate, other conditions. Among currently available studies, both variable operating conditions addition thermal storage devices have rarely...

This study investigates the energy and cost performance of hybrid renewable ground source heat pump (GSHP) and natural gas fueled fuel cell (FC) microgeneration systems serving multiple residential and small office buildings in Ottawa (Canada) and Incheon (South Korea). The study is performed by simulations in TRNSYS environment. The performance of the microgeneration system is compared to a GS...

Hybrid heating systems with ground source heat pumps (GSHP) and district cooling offer flexibility in operation to both building owners energy providers. The can be used make the system more economical environmentally friendly. However, due lack of suitable models that accurately predict long-term performance GSHP, there is uncertainty their concerns about stability temperature, which has limit...

This paper studies the efficiency of ground source heat pump(GSHP) used in refrigeration and heating, comparing it with air pump (ASHP) by means theoretical analysis experiment. The results were as follows, cooling GSHP summer is higher than that heating winter because transferred from high temperature to low during summer, which can be compared pipe; By calculating power consumption fan, found...

Building foundation piles can be used as heat exchangers in ground-source pump (GSHP) systems to provide highly efficient renewable heating and cooling (H&C). Unbalanced H&C loads lead build-up the ground, decreasing system's overall performance. In this study, introduction of natural ventilation (NV) has been examined decrease load imbalance cooling-dominated buildings improve system e...

Ground thermal properties, especially the conductivity, are of paramount importance for design ground source heat pump systems (GSHP), used space heating and cooling. However, very little information, if any, available from characteristics tropical unsaturated soils related to GSHP application. To evaluate behaviour a typical Brazilian soil, an extensive experimental investigation was conducted...

Ground Source Heat Pumps (GSHP) are high efficient HVAC equipment that provide heating and cooling for buildings. The high initial cost of drilling boreholes is one of the main reasons that hinder the widespread application of GSHP. It is very important to develop proper design methods to predict and evaluate the performance of the Ground Heat Exchanger (GHE) throughout its entire life span. In...

One of the most challenging issues in modern-day building energy management involves equipping the buildings with more energy efficient facilities. In this paper, a hybrid system for cooling/heating for a residential building is developed and optimized. The system consists of a ground source heat pump (GSHP) as well as an electric chiller (EC) and boiler. The model is implemented in MATLAB ...
