Abstract: Air conditioners are used for maintaining a good Thermal Comfort (TC) and Indoor Air Quality (IAQ) inside the air conditioned room. Performance of air conditioner generally reflects the TC, IAQ inside the room and the power consumption by the air conditioner. In this study a Split Air Conditioner (SAC) of 1.5 ton (TR) is considered for experimentation. This study investigates how the power consumptions vary with the variation of thermostat temperature and ambient temperature. It is found that in the environment of Guwahati it is not necessary to keep the thermostat temperature always below 200C to maintain the thermal comfort. This investigation shows that a good amount of power and money can be shaved by controlling the Thermostat Temperature (TT) with respect to Ambient Temperature (AT). The finding indicates that at a constant ambient temperature of 320 C when the thermostat temperature set at 180 C, 220 C and 240 C, 21% and 35% of power can be shaved in case of 220 C and 240 C in comparison to 180 C. This paper further indicates that at constant thermostat temperature of 19 0 C when the ambient temperature varies like 210 C, 240 C and 280 C, 15% and 41% power reduction occurs in case of 240 C and 210 C in comparison to 280C.
