摘　　要：墙体作为日光温室中保温蓄热的集合体,对温室的热环境至关重要。现通过对瓶胆式相变墙体热工参数的计算,研究了该新型墙体的保温蓄热性能,并将其与复合砖墙、土墙的热性能进行了对比。结果表明:该瓶胆式相变墙体的保温蓄热性能和技术经济水平总体上优于复合砖墙和土墙,适合在日光温室中使用。As a collection of solar greenhouse in heat preservation, wall is critical to the thermal environment of the greenhouse. Through studying the thermal parameters of the cavity wall with PCM, the performance of thermal performance of the new type wall were studied,and compared it with brick wall and cob wall. The results showed that the new type wall was superior to brick wall and cob wall with the thermal performance and the level of technical and economic. The cavity wall with PCM was suitable for solar greenhouses.
