This article discusses the study of energy-saving technologies that have become a topical issue today. Types of solar heating collectors, the principles of operation, and their constructive structure were studied. A new technology developed based on the analyses proposed to dry the agricultural products. Also, in the current presentation, the technologies used in the context of the technologies and the reduction issues and technologies have been considered. Experimental experiments are also provided based on the proposed technology in seasonal (spring, summer, autumn, winter). In the study case, the operation principle of the operation of a flat surface air heater is studied. The article provides the basics of twice the shortening of air canals to a common full-length sunny air heater. The study learned the issues of reducing the local resistance ratio of the device concerning a common full-wide air heater. Raise the temperature of the sun's agents discussed in the article; reduction issues are analyzed.
