Effects of different heating modes on room temperature and heat consumption of existing residential buildings in rural areas

Abstract

Affected by economic conditions, living habits and other factors, residents in rural areas have a high sense of self-regulation when heating. Rural residents often choose the corresponding heating mode according to the specific situation. This paper takes an existing building in the countryside of Zhangjiakou as the research object. The room temperature change and heat consumption under different heating modes are simulated and analyzed. The results show that the temperature of each room is higher than that of the natural room temperature under different heating modes. Even if the room is not heated during the day, the room temperature can be maintained at more than 10 °C. When the heating temperature is set to 18°C in the active state and 14°C in the sleeping state, the heat consumption can be reduced by up to 32.05% in each heating mode. The heat consumption of each mode is comparatively low, and the room temperature in each time period is similarly lower, when the heating temperature of all states is set to 14 °C.
