Study on the effect of enclosed balcony partition on indoor heating load in Xi'an

Abstract

In this paper, we focus on the effect of partition setting between enclosed balcony and its directly connected room. In residential buildings, the heat lose through balcony components makes disadvantage for energy saving. In order to avoid these adverse effects of enclosed balcony, Design Standard for Energy Efficiency of Residential Buildings in Severe Cold and Cold Zones rules that partition should be set between enclosed balcony and its directly connected room; if there is no partition, the heat transfer coefficients of the enclosed balcony envelope, as well as window to wall ratio, should be controlled within a reasonable range. To evaluate the effect of balcony partition, we use DeST-h software to simulate these two situation - balcony with partition and without partition. According to the simulation results, we come to such a conclusion that the heating load of the room with balcony partition is lower than that without, and the outside surface of balcony should be set with insulation. © Springer-Verlag Berlin Heidelberg 2014.
