The article addresses the suggestion of using local constant power plane heat source method to inspect heat transfer coefficient of enclosure structure according to the study on current situation of heat transfer coefficient of enclosure structure .

Puts forward an on-site detection method—the local heat-source method with constant heat release rate for the heat transfer coefficient of walls.

Based on the theory of transient state measurement of the thermal conductivity,a classic thermal conductivity measuring method,named plane heat source method with constant heat rate,was studied in this paper to solve the problem of measuring the thermal conductivity of insulating materials by using normal way.
