Abstract

In this paper, mathematical models on the energy and exergy performance of a variable air and water volume (VAWV) ground source heat pump (GSHP) system serving an office building in Wuhan, China, were developed. The study aims at investigating the optimal combination of supply air temperature, load side and source side supply and return water temperature to maximize the energy and exergy performance of the whole system. To find the optimal control solution for the system, Latin Hypercube Sampling Method (LHSM) was used to create data sets for training the Back Propagation Neural Network (BPNN) models to predict the energy and exergy performance and couple with Genetic Algorithm (GA). It was ..
