“…For instance, in [126], the HFM method was employed for two seasons (summer and winter) on different sides (north and south walls) of a recently built building, to assess the importance of the external environmental conditions and of the data refinement. In terms of calibration, some works are still ongoing [127][128][129].…”

“…Now, the flowmeter's accuracy will change with different pipe diameters, liquids, or pipe filling degrees. It is necessary to design the structural parameters previously and simulate a test for the flowmeter [13][14][15][16][17][18].…”

In complex industrial processes, it is necessary to perform modeling analysis on some industrial systems and find and optimize the factors that have the greatest impact on the results, in order to achieve the optimization of the industrial systems. However, due to the high-level nature or complex working mechanism of complex industrial systems, traditional principal component analysis methods are difficult to apply. Therefore, this paper proposes a characteristic model-based principal component analysis (CMPCA) to perform principal component analysis on complex industrial systems. The differential pressure flowmeter is taken as an example to verify the effectiveness of the method. Flowmeter is an indispensable instrument in measurement, and its accuracy depends on its own structural parameters. However, the measurement accuracy of some flow meters is not high, and the measurement error is large, which affects the normal industrial production process. This method is used to analyze the influence of the structural parameters of the flowmeter on its measurement accuracy, and the four most important structural parameters are found and optimized. The measurement error of the Bitoba flowmeter is reduced from 1% to 0.2%, and the measurement repeatability is reduced from 0.3 to 0.06, which proves the effectiveness of the method.

“…The main drawbacks are, firstly, that the data obtained must meet the criteria of standards, then measurement duration can be very long due to low-temperature differences between both wall sides [ 13 , 38 ], and secondly, reported data must be corrected with information about heat storage and measuring conditions to improve the estimation accuracy [ 38 , 39 ]. Although the in-situ-based measurements are easy to obtain especially if a heat flux meter is used [ 40 ], the measurements should be analyzed by a person with experience in order to obtain reliable results [ 39 ], especially when the measurement is performed in a low heat-flux regime [ 40 ].…”

In assessing the energy performance of buildings, the thermal performance of the structural components and building materials is crucial. Although reference catalogs are used to determine the thermal properties of construction materials, the use of novel materials or non-homogeneous mixtures, particularly with biomaterials, demands the development of new instruments that are capable of performing rapid, accurate and cost-effective thermal characterization. This study introduces the ambient hot-box, a new tool for measuring the thermal properties of construction components and heterogeneous materials. The paper provides a methodology for measuring a sample’s benchmark and fresh materials using a streamlined hot-box-based instrument. Utilizing samples as a benchmark material, the new instrument is assessed, yielding transmittance values with errors below 4%. The electronic circuits, measurements techniques and instrument implementation are all described.
