Degree-day G-functions approach of inverse model for ground source heat pump
摘要
Abstract
An inverse model for ground source heat pump（GSHP）,degree-day G-functions approach was proposed.The model was based on superposition theorem of geothermal heat exchangers（GHE） and degree-day model for estimating load,while model parameters were fitting by a simplex method.A residential vertical GSHP was monitored for two years.The simulated data and the monitored data were performed to validate the results from the degree-day G-functions approach and traditional duct storage systems（DST） calibrated approaches as comparison.The standard deviation of the predicted data of the degree-day G-functions approach was higher 30% than that of the DST calibrated approaches,mainly because of the predicted error of the GHE load by the degree-day model.When an inaccurate estimation of GHE parameter was used in the DST calibrated approaches,the error of the DST calibrated approaches was higher than that of the degree-day G-functions approach.It is shown that the degree-day G-functions approach is appropriate for the quantitative inverse modeling for residential GSHP.关键词
