Measuring method for on-site detection of thermal resistance of enclosing structure

The invention discloses a measuring method for on-site detection of thermal resistance of an enclosing structure. During measurement, a temperature measuring point on an inner wall surface is arranged on an adhering surface of a heat flow meter and a wall body surface, instead of a wall surface near the heat flow meter serving as the inner wall surface temperature measuring point in the prior art. Therefore, the measured heat flow corresponds to the temperature difference; and the calculation of the thermal resistance is not influenced under the condition that the tested part is in one-dimensional heat transfer. In the steady state, a calculation formula of the thermal resistance is: R=Delta T/Q, wherein Delta T refers to the difference between the temperature of the measuring point on the inner surface and the temperature of the measuring point on the outer surface, and Q refers to the heat flow of the heat flow meter reaction. Compared with the conventional measuring method, the measuring method of the invention can directly calculate the heat flow measured on site without error correction, can effectively reduce the influence of indoor environment condition and heat flow meter-added thermal resistance on the on-site measurement of the heat flow meter, provides more reasonable on-site measurement data for subsequent calculation, and reduces the error of the thermal resistance of the enclosing structure detected by the heat flow meter method.
