Determination of ground thermal properties is an important part of the design of ground-coupled heat pump system (GCHP). The number of boreholes and the depth and cost of each borehole are mainly dependent on the estimate of the ground thermal properties. This paper summarizes various determining method of ground thermal properties, the test apparatus, test procedure, theory basis and arithmetic on...
A mathematical model of the mass and heat transfer in the Standing Column Well (SCW) system is established and studied by means of a numerical solution described in this paper. Comparing the numerical solution results with test data shows that the mathematical model and numerical solution method established in this paper can reasonably describe the characters of heat and mass transfer in geothermal...
In this paper, we use the concept of neural networks to propose an intelligent tool that can we help to evaluate any aspect of earth-to-air heat exchanger. The present study focuses mostly on those aspects related to the passive heating or cooling performance of the building. Two models have been developed for this purpose, namely theoretical and intelligent. The theoretical model is developed by...
