What does \"dual temperature\" mean in the regulations for thermal insulation projects? The symbol used is M – what does dual temperature imply, and how is it translated into English?
Insulation and heat retention are both referred to as \"thermal insulation engineering.\" The term \"two temperatures\" here may refer to these two aspects; this is just my personal opinion
Dual temperature refers to the situation where a pipeline or device is subjected to different cold and hot operating conditions; the insulation method involves both thermal insulation and heat retention
It depends on the context; one can’t take things out of context
