RESEARCH TO SUBSTANTIATE THE MAIN PARAMETERS AND OPERATING MODES OF THE SOLAR DRYING MODULE AS PART OF A GREENHOUSE FACILITY

The use of solar energy and energy-saving technologies has always been relevant. However, in recent years, due to a sharp increase in energy prices (by 2–4 times) and the tightening of environmental regulations, these issues have become especially important. This article is devoted to the development of a solar drying module integrated into a greenhouse facility for horticultural production, a topic that is both timely and relevant. The study of the drying process aims to provide a scientific basis for selecting optimal methods and operating modes, as well as determining the necessary formulas and calculation expressions for designing drying units. This paper examines a solar drying module placed in the dome of a greenhouse structure. The main purpose of placing the solar drying module in the upper part of the greenhouse is to eliminate shadowing throughout daylight hours. Since the air inside the greenhouse has high humidity, the drying chamber of the helio-drying module receives air from the atmosphere in a heated form, serving as the drying agent. The proposed improvement in greenhouse design, achieved by integrating a solar drying module during the summer period-when solar activity is at its peak- offers several advantages. The southern regions of the Republic of Kazakhstan provide favorable conditions for the widespread use of solar energy in greenhouses and drying systems, as they experience high solar activity during summer, as well as spring and autumn. Theoretical and experimental research has been conducted to justify the key parameters and operating modes of the proposed helio-drying module, which is designed for drying various agricultural crops in the Southeastern regions of Kazakhstan.
