项目摘要

This paper reports the passive solar house with airflow system in brick walls. The indoor thermal environment of the brick house was measured. Then, temperature, humidity, indoor air quality and heating and cooling load were calculated using computer simulation software.1. Construction of the test house and predictions about the indoor thermal environment(1) A passive solar house with airflow system in brick walls was constructed. This test house has a Trombe wall, a solar collector and a cool tube.(2) Temperature and relative humidity of brick walls were calculated and the characteristic of brick walls was clarified.2. Measurement on indoor thermal environment of the test house(1) Compared to the heat load of the test house without the passive system, that of the test house with the passive system was 37% lower in summer and 35% lower in winter.(2) The effects of the passive system and the characteristics of the test house were clarified. In summer, the schedule of the cool tube and the cross-ventilation were considered. In winter, the effectiveness of the heating with the airflow system was clarified.(3) A month after the completion of the test house, the formaldehyde density in the room was over the guideline level (at the room with carpet). However, half a year after the completion, the formaldehyde density in the room was below the guideline level.3. Simulation of indoor thermal environment of the test houseThe effectiveness of the passive solar house in all over the country was clarified using the computer simulation. Several passive techniques were considered to reduce the energy of the brick house.

本文介绍了一种砖墙送风被动式太阳房。对砖砌房屋的室内热环境进行了测量。然后利用计算机模拟软件计算了室内温度、湿度、室内空气质量以及热负荷和冷负荷。试验房屋的建造及室内热环境的预测(1)建造了一座砖墙送风系统的被动式太阳房。该试验房屋由特龙贝墙体、太阳能集热器和冷管组成。(2)计算了砖墙的温度和相对湿度，明确了砖墙的特性。试验房室内热环境的测量(1)与未安装被动式系统的试验房相比，试验室夏季热负荷降低37%，冬季热负荷降低35%。(2)阐明了被动式系统的影响和试验室的特点。在夏季，考虑了冷管和交叉通风的时间安排。在冬季，阐明了送风系统采暖的效果。(3)试验室建成一个月后，室内甲醛浓度超标(有地毯的房间)。但竣工半年后，室内甲醛浓度均低于指导值。实验房屋室内热环境的模拟通过计算机模拟，阐明了被动式太阳房在全国各地的应用效果。考虑了几种被动技术来降低砖房的能量。
