Supply air conditions and Comfort in air conditioning of spaces

Abstract

Air conditioning of spaces is essentially meant to provide comfort to the occupants by controlling factors which affect the comfort. Several factors affect the comfort and efficiency in indoor environment. Temperature, velocity, humidity, Temperature of surrounding surfaces, Odour, dust and lighting are some of the major factors affecting human comfort in air conditioning. The factors of thermal interaction with the human body affect the human comfort. For the design of an air conditioning system, the air distribution is of great importance in ensuring human comfort in conditioned spaces. Air distribution is meant to supply the conditioned air with designed supply air parameters. When this air is distributed in the conditioned space, its effect on overall environment of the conditioned space is also to be known. To investigate the effect of supply air conditions of conditioned air experimental and numerical methods are being used by the researchers. The objective of this paper is to present literature on air conditioning for comfort in conditioned space and the application of Computational Fluid Dynamics (CFD) in evaluation and simulation of indoor environment.
