The ground-source heat pump is a system which takes the shallow surface soil energy as the source of heating and cooling. The temperature of ground source is relatively stable throughout the year, which makes the ground-source heat pump have the higher operation efficiency compared with the traditional air-conditioning system.Study on the ground-source heat pump with properties of thermal dynamics used in heating and air comditioning by ecomomic analysis is still an important issue. In this paper, the ground-source heat pump and the traditional heating and air-conditioning system have been compared in terms of their economic competitiveness. Firstly, it is required to compare the ground-source heat pump with the traditional heating method in terms of the heating economy. Afterwards, it is necessary to compare the ground-source heat pump with the conventional electric refrigeration in terms of the air-conditioning economy. Finally, it is needed to conduct the comprehensive and economic analysis for the ground-source heat pump and the boilers and air conditioning, which includes four programs.

The design of ground source heat pumps is a fundamental step to ensure the high energy efficiency of heat pump systems throughout their operating years. To enhance the diffusion of ground source heat pump systems, two different tools are developed in the H2020 research project named, “Cheap GSHPs”: A design tool and a decision support system. In both cases, the energy demand of the buildings may not be calculated by the user. The main input data, to evaluate the size of the borehole heat exchangers, is the building energy demand. This paper presents a methodology to correlate energy demand, building typologies, and climatic conditions for different types of residential buildings. Rather than envelope properties, three insulation levels have been considered in different climatic conditions to set up a database of energy profiles. Analyzing European climatic test reference years, 23 locations have been considered. For each location, the overall energy and the mean hourly monthly energy profiles for heating and cooling have been calculated. Pre-calculated profiles are needed to size generation systems and, in particular, ground source heat pumps. For this reason, correlations based on the degree days for heating and cooling demand have been found in order to generalize the results for different buildings. These correlations depend on the Köppen–Geiger climate scale.

In order to contribute to widespread use of RES in Turkey, a solar-assisted ground source heat pump system was modeled using TRNSYS software and simulated for heating and supplying daily hot water to meet the needs of a restaurant in five sample provinces having different climatic conditions. During the simulation, the dining room temperature of the restaurant was kept constant at 22?C during the winter season and a total of 300 Lph of water (55?C) was used for 15 minutes four times a day. According to the simulation results, power consumption rates in the solar-assisted ground source heat pump system were determined as about 60% for the heat pump, 16% for heaters, 14% for the ground pump and 8% for fans and other pumps. The highest power consumption, as expected, was obtained for Hakkari Province (6723 kW) in the Eastern Anatolia region, which has a cold climate, while the lowest power consumption was obtained for Izmir Province (2822 kW) in the Aegean region, which has mild climatic conditions. The lowest seasonal performance factor and solar factor values were calculated as 2.27 and 32% for Hakkari and the highest as 2.71 and 56% for Izmir, respectively.

Future Work

This paper discusses the research and the state-of-art practices on ground source heat pump systems (GSHP) in China. It introduces the Chinese patents on GSHP. The GSHP development policies of China, including incentive mechanism, relevant codes and regulations, are also introduced. In addition, this paper discusses and summarizes the shortages and imperfects of the current research of the GSHP system and gives some recommendations for future work. At last, the authors give some advice for the development of ground source heat pump. For more reliable statistics on geothermal energy use, the obligation to supply an installation report to the relevant authority should also be imposed on the rural buildings besides urban buildings. GSHP systems are suitable for heating and cooling of buildings and so could play a significant role in reducing CO2 emissions.
