Specific heat capacity is one of the prominent and deciding factors for selection of thermal insulation materials in thermal engineering. In recent times, there has been a great advancement in the manufacturing of a variety of advanced materials in order to meet the modern needs for thermal insulation. Unfortunately, certain drawbacks like high cost of procurement, low accuracy, and limited suitability are associated with the current device that can be used to probe the specific heat capacities of thermal insulators. Thus, there is need to devise a means of addressing the situation. A device, named SEUR’s apparatus, was designed, constructed, and used to determine specific heat capacities of some thermal insulators. Measurements were taken on 2 days, and KD2-pro meter was employed to obtain reference values. The percentage error values in the specific heat capacity of plastic (solid), asbestos, and paperboard were found to be 0.09%, 0.14%, and 0.13% for day 1 measurements and 0.08%, 0.17%, and 0.13% for day 2 measurements, respectively. Reproducibility values of 7.4%, 6.4%, and 8.2% were obtained for the plastic, asbestos and paperboard, respectively. These values fall within the range for unconditional acceptability of a test device. Results obtained with the use of the SEUR’s apparatus are reliable, valid, and of high accuracy. The apparatus is cost-effective and very suitable for use in quick determination of specific heat capacity of porous, non-porous, homogeneous, or heterogeneous thermal insulating materials.

一种测定绝热材料比热容的装置的设计与性能评价

比热容是热工工程中选择保温材料的突出和决定性因素之一。近年来，为了满足现代对隔热的需求，各种先进材料的制造取得了巨大进步。不幸的是，某些缺点，如采购成本高、精度低和适用性有限，与当前可用于探测热绝缘体比热容的设备有关。因此，需要设计一种方法来解决这种情况。一种名为 SEUR 装置的装置被设计、制造并用于确定某些绝热体的比热容。在 2 天进行测量，并使用 KD2-pro 测量仪获得参考值。发现塑料（固体）、石棉和纸板的比热容百分比误差值对于第 1 天的测量为 0.09%、0.14% 和 0.13%，对于第 2 天的测量为 0.08%、0.17% 和 0.13% ， 分别。塑料、石棉和纸板的再现性值分别为 7.4%、6.4% 和 8.2%。这些值在测试设备无条件可接受的范围内。使用 SEUR 仪器获得的结果可靠、有效且准确度高。该装置具有成本效益，非常适合用于快速测定多孔、无孔、均质或异质绝热材料的比热容。第 2 天的测量分别为 0.17% 和 0.13%。塑料、石棉和纸板的再现性值分别为 7.4%、6.4% 和 8.2%。这些值在测试设备无条件可接受的范围内。使用 SEUR 仪器获得的结果可靠、有效且准确度高。该装置具有成本效益，非常适合用于快速测定多孔、无孔、均质或异质绝热材料的比热容。第 2 天的测量分别为 0.17% 和 0.13%。塑料、石棉和纸板的再现性值分别为 7.4%、6.4% 和 8.2%。这些值在测试设备无条件可接受的范围内。使用 SEUR 仪器获得的结果可靠、有效且准确度高。该装置具有成本效益，非常适合用于快速测定多孔、无孔、均质或异质绝热材料的比热容。使用 SEUR 仪器获得的结果可靠、有效且准确度高。该装置具有成本效益，非常适合用于快速测定多孔、无孔、均质或异质绝热材料的比热容。使用 SEUR 仪器获得的结果可靠、有效且准确度高。该装置具有成本效益，非常适合用于快速测定多孔、无孔、均质或异质绝热材料的比热容。
