Abstract:Owing to the cold and windy weather in southern Liaoning province in winter, the heat loss through doors and windows accounts for 20 to 30 percentage of the whole heat loss of house. To decline the heat loss through doors and windows, focusing on the typical rural house, an energy consumption system is built. On the basis of it, a study about the influence on the indoor temperature of windows' heat transfer coefficient, airtightness, size and the outside door is made. The results show that on the condition of the same heat supply, the temperature of the room, which installs single frame double glass windows, is 2 centigrade higher than which installs single frame single glass windows, and is 0.4 centigrade higher than which installs double frames single glass windows. The indoor temperature of room installing casement windows is 0.5 centigrade higher than the room installing sash windows. For the southern window, the heat flowing into the house is more than the heat losing through window, and the bigger the window, the higher the indoor temperature. However, regarding there is no direct solar radiation in the north, for the size of northern window, the little, the better. In rural house, the foyer can prevent cold air from flowing into the rooms directly. In other words, there is a temperature buffer around rooms. The simulation results show that the existence of foyer can raise the temperature of kitchen 1.1 centigrade. The study of this paper will offer theoretical basis to the new countryside construction.
