1986年秋,黑龙江省望奎县农村能源办公室,在有关单位协作下,将一座普通的平房(建筑面积为96m~2)改建成被动式太阳房,经过一冬的实际使用和测试,效果显著。望奎县地处黑龙江省的中西部,北纬47°,东经127°,属于高纬度寒冷地带。冬季采暖期长达5个半月,年最低温度在零下35℃以下,故冬季需大量采暖燃料,这对平原地区农村来说,形成了较大的生活能源的供求矛盾。另一方面,这个地区太阳
In the fall of 1986, the rural energy office of Wangkui County, Heilongjiang Province, with the cooperation of the relevant units, converted an ordinary bungalow (building area of 96m~2) into a passive solar house. After a winter of actual use and testing, the effect was remarkable. Located in the Midwest of Heilongjiang Province, Wangkui County is 47 degrees north latitude and 127 degrees east longitude and belongs to the cold latitudes of high latitudes. The heating period in winter is as long as 5 and a half months, and the minimum temperature in the year is below -35°C. Therefore, a large amount of heating fuel is needed in winter. This poses a great contradiction between the supply and demand of living energy in the rural areas of the plains. On the other hand, the sun in this area
