The Effect of Spray Cooled and Air Cooled Condenser of a Window Air Conditioner on Human Thermal Comfort: Experimental Investigation

Abstract

Human comfort is always interlinked with the working environment as most of the time is spent indoors. High level of excellence in indoor environment is achieved by architects, building engineers and civic amenity managers. They provide the required human comfort, i.e. thermal, aural and visual comfort in order to increase the working efficiency of humans. As the living standards are improving day by day, the air conditioning of working space is required to be considered as top most priority. Thus, it necessitates to know by different experiments, how quick we can gain the suitable and optimum parameters in a particular working environment. This paper provides a comparative study between the air cooled condenser and spray cooled condenser of an air conditioner in order to evaluate the effectiveness of the two and the time period both the condensers take to bring the working environment to the most acceptable environment quality (the comfort zone) required for humans. In this paper, the experiment is performed for summer air conditioning where the ambient temperature varies from 31–43 °C. Experimental results show that the use of spray cooled condenser is much effective and provides the required comfort zone in lesser time as compared to air cooled condenser.
