Abstract The increasing use of ground-source heat pumps (GSHPs) for heating and cooling buildings raises questions regarding the technical potential GSHPs their impact on temperature in shallow subsurface. In this paper, we develop a method using Machine Learning to estimate GSHPs, which enables such an estimation Switzerland with limited data computational resources. A training dataset is cons...

Airport is a typical integrated energy system in park with various requirements. In this paper, multi-dimensional quantitative analysis of performance indicators was conducted by using comprehensive weighting method based on the analytic hierarchy process (AHP) and anti-entropy weight method. A distributed evaluation matrix model used to evaluate compare different designs. The results showed th...

A ground source heat pump system (GSHP) with a exchanger (GHE) is renewable and green technology used for heating cooling residential commercial buildings. An innovative U-Tube pipe configuration suggested to enhance the transfer rate in vertical (VGHE). Laboratory experiments are conducted compare thermal efficiency of VGHEs two different configurations: (1) an (single outer fins) (2) single U...

Geothermal heat pumps are becoming more and more popular as the price of fossil fuels is increasing and a strong reduction of anthropogenic CO2 emissions is needed. The energy performances of these plants are closely related to the thermal and hydrogeological properties of the soil, but a proper design and installation also plays a crucial role. A set of flow and heat transport simulations has ...

The multi-species transport model MT3DMS is applied to simulate heat transport in shallow confined aquifers. This is done by taking advantage of the mathematical similarities between the description of heat and solute transport. A comprehensive analysis on the applicability of MT3DMS (version 5.2) for heat transport simulation of closed shallow geothermal systems is shown. MT3DMS simulations ar...

For ground-source heat pump (GSHP) installations, it is important to predict the thermal performance and economic feasibility prior to the introduction of the system. Numerical modelling can be used as an analytical method to accurately predict the thermal performance of such system. It is desirable that the modelling to incorporate seasonal variation during long period of operation, which woul...
