Investigating parameters affecting the indoor temperature drop after a power cut -In-situ measurements and simulations

摘要

When looking at energy supply on a larger scale than to a single building, such as to a neighbourhood or a city, the combined effects of peak power demands can be seen to cause problems on the production side. These can be both economic and environmental and lead to the emission of greenhouse gases when fossil fuels are used'to meet these peaks. Encouraging the demand side to reduce their power demands at these time could be one way of dealing with this issue. This paper investigates the temperature drops after a power cut both through measurements in the field and comparisons of these results to simulations. A single-family dwelling in use and a multi-family dwelling about to be decommissioned were studied. The comparisons showed that the rates of the temperature drops in reality were slower than in the simulation models. A parametric study of the variables affecting the temperature drops, such as furniture, showed that they might explain these differences. (C) 2017 Elsevier Ltd. All rights reserved.
