摘要
论述相变材料是被动式太阳房理想的贮热材料，其溶点宜选择为１２℃。通过实验，初步探明Ｎａ２ＳＯ４·１０Ｈ２Ｏ（芒硝）中加入适量的ＮＨ４Ｃｌ、ＮａＣｌ等物质可以达到要求。
This paper discusses that phase change materials are good heat store materials for the passive solar house. The melting point of the phase change materials is 12℃。 We ascertain elementaly that Na 2SO 4·10H 2O which is mixed with NH 4Cl, NaCl, etc. is suitable by experiment. It also discusses a way to make Na 2SO 4·10H 2O without freezer.
