Research process of preparation of a drying agent in a solar thermal collector

Abstract

Article describes the construction of the solar collector. The article contains the results of the research of the influence of the geometric and technological parameters of the collector and the ambient temperature on the temperature of the prepared drying agent. The temperature of the prepared drying agent increases with increasing inlet air temperature and the area of the heat collector. An increase in the flow rate of the collector is accompanied by a decrease in the temperature of the drying agent. The highest temperature of the drying agent is observed at the working area of the collector 2 S=6м . Mathematical method of planning the experiment, using a symmetric non-composite plan for the implementation of the second-order Box-Bank experiment allows to study the process of heating the drying agent in the solar thermal collector. To obtain a mathematical model of the process of heating the drying agent by passing air through the solar collector, a three-factor experiment was conducted. Received a mathematical model of the heating process and conducted a three-factor experiment. Conducted the results of a three-factor experiment, according to a three-level second-order plan on a computer (using Mathcad 14), obtained a regression equation, where the function of response is the temperature of the drying agent. The obtained regression equations make it possible to construct the response surfaces and their two-dimensional sections, as well as to analyze the dynamics of change in the agent temperature at the outlet of the reservoir.
