Numerical investigation of the effect of radiator placement on temperature distribution in a room

Abstract

This study analyses the impact of radiator placement on temperature distribution in a room using CFD analysis. Radiators are typically placed under windows or on outer walls. However, in the area under study, where there are large windows extending to the floor on the outer walls, the radiator was positioned on the empty inner wall. Two variations of the analysis were conducted using the ANSYS Fluent program. One variation involved a vertical installation of an aluminium panel radiator of the same length as the existing radiator on the outer wall next to one of the two windows. The other variation involved the installation of two radiators of the same length as the existing radiator next to the windows. The results showed that the room heated up faster when two radiators were used compared to other alternatives. Heating a room with two radiators of equal length and surface temperature results in a faster temperature increase. When a radiator is positioned vertically, the average temperature remains the same as the current situation. Using multiple smaller radiators instead of a single large one that provides the same amount of heat allowed the environment to warm up more quickly.
