Numerical Evaluation of Moisture Effects on the Underground Thermal Storage System
摘要
The RESHeat (Renewable Energy System for Residential Building Heating and Electricity Production) system is a typical application of the utilisation of sun-tracked Photovoltaic Thermal (PVT) panels and underground heat storage units. This work introduces a MATLAB simulation model coupled with moisture and heat transfer processes. Validation of the proposed model from experimental measurements was conducted. The simulations were performed for a single year of RESHeat system operation for demo sites located in Cracow City. Results showed relative error between calculation and measurement varies from 0.258% to 5.829%, along with the same temperature trend. A Finite Volume Method is used to simulate coupled heat transfer in the ground.
