In order to increase the diagnostic accuracy of ground-source heat pump (GSHP) system, especially for multiple-simultaneous faults, the paper proposes a multi-source information fusion based fault diagnosis methodology by using Bayesian network, due to the fact that it is considered to be one of the most useful models in the filed of probabilistic knowledge representation and reasoning, and can...

In the current context of huge global energy consumption and harsh climatic conditions, efficiency sustainability buildings have received much attention. The nearly zero-energy building (nZEB) is a feasible solution for solving crisis in sector recent years, it important to study adaptability its technology system. However, existing studies not addressed well issue impact complex diverse climat...

The optimization design of a ground source heat pump (GSHP) system can be crucial in improving its performance and economic competitiveness. effect probabilistic uncertainties variables GSHP was analyzed using reliability-based (RBDO) method. An analytical borehole transfer model selected as the frame energy simulation this work. With goal to minimize cumulative costs over 20-year lifespan syst...

In response to the call for global carbon peaking and neutrality, this study mainly focuses on comparison of energy-related emissions performance two promising heating, ventilation, air-conditioning technologies (a ground source heat pump (GSHP) cogeneration systems) over both short (2021–2030) long (2031–2050) periods, considering UK decarbonization plans. The simulation model building with GS...

Ground Heat Exchangers (GHEs), buried in the ground either horizontally or vertically (in a borehole), are coupled with heat pump to form Source Pump (GSHP) system, which is type of Renewable Energy System that exploits geothermal energy for space heating and cooling. GSHP systems proposed as an alternative conventional Air Pumps (ASHPs) they exhibit higher efficiency. In this study, difference...

Geothermal energy exhibits considerable development potential in space heating. Shallow geothermal stored the soil form of low-grade is mainly extracted via ground source heat pump (GSHP) system. GSHP systems use subsoil as a source, typically involving vertical borehole exchanger (BHE) to extract from formation. Accurate measurement thermal properties formation very important for design BHEs. ...

Abstract Ground source heat pumps (GSHPs) are one of the renewable energy technologies with features high efficiency, saving, economic feasibility and environmental protection. In China, GSHPs have been widely used for building heating cooling in recent years, shown great potential future development. This paper summarizes classification, development history, use status shallow GSHPs. Several t...

Geothermal heat is an increasingly adopted source for satisfying all thermal purposes in buildings by reversible pumps (HP). However, residential located moderate climates, geocooling, that implies the use of geothermal cooling without operation HP, efficient alternative space not yet explored enough. Geocooling allows two main benefits: to cool high energy efficiencies improving summer comfort...
