Method for determining the equivalent thermal conductivity of wall materials1 ScopeThis 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 definitionsThe 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 principleThis 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 device4.1 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. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32981-2016_English be delivered?Answer: Upon your order, we will start to translate GB/T 32981-2016_English as soon as possible, and keep you informed of the progress.
