Abstract
The gray correlation analysis is employed to analyze the effect of the row number of thermal storage tubes, the air circulation rate and the air temperature on efficiency of wood drying in solar drying system with phase change material (PCM) thermal storage, the relative order of influencing factors on wood drying process is determined. It indicated that air temperature is the 1st key influencing factor in the solar drying system, followed by the air circulation rate, and then the row number of thermal storage tubes. This result is of practical significance for the optimization of the drying process.
Highlights
Use of solar energy for drying agricultural products is one of the important production activities, which were carried out very early in human society [1]
China has abundant solar energy resources, it has about two-thirds of land with annual irradiation time over 2200 hours [1], the annual total radiation is over 5000 MJ / m2, the total solar radiation in the country is 3340 MJ / m2 ~ 8400 MJ / m2 per year
Look at the absolute correlation matrix A, it can be found that there exists εi2>εi1>εi3, i=1,2,3; order of priority is X2, X1 and X3, which means that the impact of circulation rate of air is the main affecting factor, followed by the number of thermal storage tube rows, and the air temperature
Summary
Use of solar energy for drying agricultural products is one of the important production activities, which were carried out very early in human society [1]. The use of solar drying in wood production has been launched in many countries [2,3,4,5]. The factors that restrict the use of solar drying include mainly the low energy density of solar resource, the seasonal performance, and poor storage of energy. The order of affecting factors needs to be recognized by gray correlation analysis. Yu Jie and Zheng Maosheng: Grey Correlation Analysis of Factors Affecting Wood Drying in PCM. The gray correlation degree analysis is employed to study the influence of affecting factors on wood drying in solar drying system with phase change thermal storage conducted by [6]
