Energy audit in residential building – replacement of portable air conditioner by an energy efficient centralised air conditioner

ABSTRACT

This article deals with the energy audit in the residential building in OMR, Chennai (latitude and longitude are: 13.067439, 80.237617), India. The present article aims to identify the inefficient electrical utilities in operation such as washing machine, refrigerators, air conditioners and major lighting equipment; based on the collected data, the decision will be made to replace them or service them. The collected data suggest that the air-conditioner unit consumes the 24% of daily total power consumption of the residential building. It is decided to modify the existing air-conditioning arrangement by the energy-efficient system without compromising human comfort. The audit team strongly recommends replacing the individual A/C systems such as window and splitting A/C systems by the centralised air-conditioner unit.
