低温系统隔热层设计的新原则

NEW DESIGN PRINCIPLE OF LOW TEMPERATURE SYSTEM INSULATION

依据热力学第二定律 ,从减少不可逆损失的角度出发 ,提出了低温系统隔热层设计的新原则 ,即单位面积熵产率限制的设计原则 ,并与传统的设计原则进行了比较。

In view of reduction of irreversibility,a new design principle of the low temperature system insulation is proposed according to the thermodynamic second law.The new principle,that is the restriction of entropy generation rate unit area,is compared with the conventional design principle.
