THE NATURE OF THE TEMPERATURE DISTRIBUTION IN A ROOM WITH A RADIATOR HEATING SYSTEM, DEPENDING ON ITS HEIGHT AND THE CONSTRUCTION AREA

Abstract

In the cold season, maintaining the desired room temperature is often provided by instrument heating, designed to compensate for heat losses. In this case, the temperature stratification along the height of the room, created by the convective heat flow from the heater, is usually not taken into account. According to the established design practice, the choice of the heating surface is carried out according to the temperature averaged over the volume of the room. At the same time, there is a high risk of underheating of the working area, especially in the cold part of winter in areas with a low temperature of the coldest five-day period. To study this issue, calculations were performed using the Ansys Fluent software package. The simulation of the process of heat and mass transfer in the volume of the room under known boundary conditions was carried out for the formation of a "thermal cushion" and the determination of the air temperature in the working and upper zones of the room.
