摘　　要：火炕是北方村镇最广泛使用的采暖方式。旧式火炕存在炕面温度不均匀、室内热环境差和室内空气品质差等问题。火墙式火炕具备火炕和火墙的双重热工性能，不需要辅助设备即可满足采暖要求，是经济环保型的火炕，适应建设社会主义新农村的需要。本文以大连瓦房店一户农宅为对象，采用实地测试的方法，研究了火墙式火炕的热工性能及其作用下的室内热环境。结果表明，火炕以辐射散热为主要形式，约占总散热量的60％；火炕中增加火墙结构，可提高炕面温度的均匀性和火炕的即热性，在冬季室外温度较低的情况下，仍可使室内温度维持在15—18℃。Kang is the most popular heating equipment in north rural areas. As for the old type Kang, the temperature is unevenly distributed on the bed surface, moreover, the indoor thermal environment is weak and the indoor air quality is poor. Hot-wall type Kaug is with both the thermal performance of Kang and hot wall,so it can meet the heating need of the people living in rural areas without using auxiliary appliances. What＇s more,hot-wall type Kang is a piece of economical and environmentally friendly equipment, meeting the need of building the socialist countryside. In this paper,focusing on a rural household in Wafangdian of Dalian,the thermal performance of hot-wall type Kang and indoor thermal environment were studied by using on-the-spot test. The results indicated that the hot-wall type Kang was mainly in the form of radiation,which was about 60% of the total quantity of heat dissipation. Furthermore,by adding the hot wall structure to the Kang,the temperature was distributed more evenly on the bed surface and the Kang could be heated more quickly. In winter, the indoor temperature could be maintained at 15 - 18 ℃ with low outdoor temperature. ＂
