“…Она позволяет осуществлять визуальный анализ взаимодействия и преобразования тепловых потоков, как на границе раздела фаз, так и внутри тела. Значительная часть работ посвящена математическому моделированию процесса сушки, который осуществляется с целью кинетического расчета сушильного аппарата, поиска путем численного анализа процесса желаемого технологического и конструктивного решения [51][52][53][54]. Математические (аналитические) методы не требуют предварительного (перед расчетом) опытного исследования процесса сушки в условиях, а оперируют только теплофизическими характеристиками материала [55,56].…”

This article uses BIM technology to simulate HVAC in a commercial building. And use fractional differential equations to verify the set temperature, humidity, and other related parameters. The experiment takes an air-conditioned room model as the research object and uses the thermodynamic characteristics to establish a dynamic mathematical model of differential equations. Research shows that the multiple electric heat pump equipment aggregation groups discussed in this article are a good resource for user-side demand response. The air-side flow rate disturbance of the building HVAC has the greatest impact on the heat transfer of the surface cooler. As the air velocity increases, the rate of increase in heat exchange will decrease.

“…The dryer has several advantages addressing to fast drying rate due to good contact between gas and solid as well as mass and heat transfer, shorter drying time, small drying device with large capacity, high thermal efficiency, low cost operation, easier monitoring, and so on [12,13]. Previous study about the use of fluidized bed dryer about corn drying using a heat pump with heating air to dryer with minimum speed of fluidization is 1.54 m/s and air speed 13 m/s and temperature about 60℃ [14]. Other study about the influence of hot air on drying quality purple rice using fluidized bed drying carried out with hot air temperature 150℃ [15].…”

Rice is the main food in Indonesia. Rice drying by using the traditional method directly under the sun light can require a long time to complete. The aim of this study is to investigate the appropriate kinetics modeling of rice with applied by fluidized bed dryer. A rice bed with 2-cm thickness has been dried at various temperatures (50℃, 60℃, and 70℃) with air velocity of 10 m/s applied from hot air fluidized dryer obtained from pyrolysis process. The appropriate rice drying kinetics modeling has been selected based on the agreement between experimental results and seven drying kinetics equations available namely the drying kinetics modeling of Newton, Page, Henderson-Pabis, Logarithmic, Midilli, Two Term, and Verma. The degree of accuracy for the kinetics modeling is determined based on six statistics parameters namely the coefficient determination (R2), mean absolute deviation (MAD), mean square error (MSE), root mean square error (RMSE), Akaike information criterion (AIC), and Schwarz information criterion (SIC). The results of the study show that the Verma drying kinetics modeling is the most appropriate model for rice using fluidized bed dryer with all given temperatures (50℃, 60℃, and 70℃) with regard to six given statistics parameters (R2, MAD, MSE, RMSE, AIC, and SIC).
