RESEARCH OF STRUCTURAL AND MECHANICAL PROPERTIES OF MEAT AS AN OBJECT OF PROCESSING IN MEAT COMMINUTOR

Abstract

This work is dedicated to the study of the energy efficiency of using electric heating systems in the classrooms of Ivano-Frankivsk National Technical University of Oil and Gas (IFNTUOG), where the actual state of heating systems and their efficiency in educational building №9 were determined. An experimental study was conducted, which included determining the heating and cooling time of working surfaces and the distribution of temperatures across them in a classroom; determining the distribution of thermal energy at several levels of the room.

Experimental data were obtained to evaluate the effectiveness of different electric heating systems in classrooms in standby mode, which allowed selecting the infrared heating system based on ceiling heaters as the most optimal technical solution for providing an acceptable level of comfort and energy efficiency. The effectiveness of using air thermostats for the electric heating system based on infrared heaters, which operates in standby mode, leading to excessive electricity consumption, was also studied.

The results confirm that the heating system using infrared panels ensures even heat distribution, maintains comfortable temperature and humidity conditions, and is distinguished by high energy efficiency. In contrast, the use of electric convectors with an inefficient water heating system does not provide adequate air heating, especially in spacious and high rooms, where heat dissipates quickly due to insufficient insulation.

The data obtained during the scientific research, along with previous studies, allow for the development of an automatic intelligent heating and ventilation control system that will use the most advanced research results in the field of efficient operation of engineering systems in educational institutions.
