备注

陕南山地民居环境存在节能发展落后,夏季室内热环境差等问题.为了研究当地室内热环境状态,提高民居使用舒适和降低能耗,对该地区典型民居进行夏季室内外热环境测试.通过测试量化了当地民居夏季热环境状态,测试表明:太阳辐射以直射为主,室外温度昼夜温差大; 民居一层基本可以满足舒适要求,中间层大部分时间满足舒适要求,顶层偏离舒适要求.根据能耗计算结果,提出陕南民居一层和中间层可不设置空调,顶层受太阳辐射影响空调能耗较高,应设置隔热构造降低空调能耗.

The resident environment in the southern Shaanxi has the problem of energy conservation and development, and the indoor thermal environment is not comfortable in the summer. The thermal environment of local folk houses was quantified by testing both indoor thermal environment and outdoor thermal environment showing that the most part of solar radiation is from direct radiation and the outdoor temperature is shown as two extreme distribution states. The first floor of the house can meet the comfort requirements,the middle part is pleasing to live in most time of a day and top floor is away form the thermal comfort range. According to the calculation result of energy consumption, it is suggested that in the south of Shaanxi, air-conditioner is not needed to set in the first floor and middle floor. As for the top of the building, it is influenced by solar radiation and the energy consumption is high. Thus the insulation structure should be set up to reduce the energy consumption of air conditioner in the top area.
