Method for determining the equivalent thermal conductivity of wall materials
1 Scope
This standard specifies the terms and definitions, principles, measuring devices and test methods for determining the equivalent thermal conductivity of wall materials.
This standard applies to the construction of wall heterogeneous materials.
2 terms and definitions
The following terms and definitions apply to this document.
2.1
Equivalent thermal conductivity
λe
In the stable heat transfer state, the characterization of 1m thick heterogeneous material, the surface temperature difference of 1K, the unit time through 1m2 area transfer
Of the heat, with the symbol λe said, the unit is W/(m · K).
2.2
Heterogeneous materials
Any of the various components of the physical and chemical properties of different materials.
3 principle
This method is based on the principle of stable heat transfer. The filler (known material thermal conductivity), the specimen (placed in the filler) installed in the cold box and
Between the box, control the temperature of the cold box and the metering tank to maintain the thermal conduction balance, in the same conditions, respectively, through the filler and the specimen test the heat
Flow, according to the temperature and power changes calculated the equivalent of the specimen thermal conductivity λe.
4 measuring device
4.1 device structure
The measuring device (see Fig. 1) consists of five parts. cold box, protective box, metering box, test box, control and data acquisition and processing system. Specimen
Installed between the metering tank and the cold box, the test box is connected with the metering box. Install the heating unit and the refrigeration unit in the cold box to simulate the constant cold chamber
Experimental conditions. In the outside of the measuring box placed protective heat box, in order to reduce the tank temperature loss (general protection box temperature set value and metering tank temperature
Set the same value). The temperature sensor monitoring and determination process is arranged in the box.
