Study on Dynamic Thermal Performance of Hollow Block Ventilated Wall

摘要

In this paper,a heat transfer model of the hollow block ventilated wall is established using the numerical simulation method to obtain the dynamic thermal performance of this new envelope.And three different sizes of the hollow block wall under three conditions are studied.The results show that,the internal wall surface temperature of the hollow block wall is lower and the heat transfer from the outdoor to indoor is reduced significantly compared with the conventional wall.Furthermore,with the increase of the thinness of the cavity,the thermal performance of the hollow block ventilated wall becomes better.
