Air Distribution in Air Conditioned Spaces to Simulate Indoor Thermal Environment for Variable Supply Air Conditions

Human comfort is the need of modern society. Air conditioning is now becoming necessity for the man and machine both. Not only human but machine performance is also affected by the thermal conditions around them. With the changing time and the raising importance of comfort, engineers and researchers are continuously working to provide means of comfort conditions. Air conditioning has been widely used in residential, industrial and commercial applications where the occupants are provided comfort environment by supplying conditioned air with suitable temperature and velocity. The temperature and velocity are the two most important factors which need to be given due consideration in assuring comfort in air conditioned spaces. The comfort condition is achieved is by distribution of conditioned air in the spaces. If the air is not distributed effectively it will cause poor indoor thermal environment and also non-economic air conditioning. This research is focused on establishing numerical methodology using CFD and presentation of temperature and velocity variation when the conditioned air is supplied in a space for various supply air temperature and velocity is kept constant. The results show that uniform thermal environment is produced when the supply air temperature has 297K value.
