Validation of Veracity on Simulating the Indoor Temperature in PCM Light Weight Building by EnergyPlus

摘要

This article surveys the EnergyPlus constructions solution algorithm and heat balance method in EnergyPlus, presents the new conduction finite difference solution algorithm and enthalpy-temperature function features, describes the implementation of the module, and validates the veracity of the possible applications for the capabilities in EnergyPlus by PCM experiment dates. The most relativity difference is 12.41% and the least is 0.71% between the simulation and testing value in sequential 36h on the A envelope condition, wheras on the B envelope condition the most relativity difference is 8.33% and the least is 0.33% in sequential 72h.The results to date has shown good agreement with well established in this simulation tools and shown that the algorithm incorporated into EnergyPlus can simulate the PCM in building construction.
