Study on Thermal Comfort in Industrial Buildings, Heated by Radiation

Abstract

This paper is focused on a study between different heating systems commonly used in industrial installations. Industrial heating systems generally raise difficult problems in choosing the most economical system. If several solutions technically meet the requirements of the indoor climate, in terms of energy efficiency we must focus on the optimal solution. The study was conducted to choose the optimal heating solution for an industrial hall, from the point of view of evaluating the efficiency of the installation of an exhaust gas recirculation equipment. The heating of industrial premises generally raises difficult problems due to the diversity of the types of buildings encountered, the variety of activities carried out and the need to choose the most economical system, both in terms of investment and operation. The radiation heating system using natural gas offers the solution of this problem, in situations where the classic heating systems (hot air heating or static bodies) cannot ensure optimal indoor conditions (in the sense that they do not achieve a relatively uniform temperature in the heated space, cause drafts and have low yields). For spaces with a high height (over 4m) these systems can only be considered satisfactory in the case of general heating with very high energy consumption. From the study performed, but also from the specialized technical literature, it is concluded that these systems offer an energy saving, compared to the classical systems.

"The influence of the vertical temperature gradient on working conditions in industrial halls heated with radiant tubes. Case Study"

“…For industrial buildings and the heating systems that serve them, the energy efficiency of the system must be correlated both with ensuring working conditions and with ensuring inside parameters specific to technological processes [4], [5], [6], [7], [8], [9], [10], [11]. On the other hand, only the thermal justification for a heating system related to industrial buildings is not enough to decide whether an investment is economically efficient.…”

“…On the other hand, only the thermal justification for a heating system related to industrial buildings is not enough to decide whether an investment is economically efficient. Practically, from an energy point of view, the options for choosing the heating system can be compared based on the following criteria [5]:…”
