Abstract

Global warming has led to severe climatic changes worldwide, including rise in sea level, depletion of ozone layer and many others. As a consequence of the same, the scientific community is focusing its efforts towards harnessing renewable energy resources and development of environment friendly energy efficient systems. However, the initial cost and specific operating conditions for adapting these innovative technologies are of major concern towards their practical implementation.

Based on the climatic conditions in India, heating, ventilation and air conditioning (HVAC) is a major contributing factor in total power consumption of residential, commercial and industrial sectors. Anticipating the rise in per capita consumption in the decade to come, the conventional energy sources would not only be insufficient to make ends meet, but also affect climatic conditions. The present work describes a few innovative technologies in the HVAC industry which includes improvement in products with conventional energy sources as well as combination of traditional and renewable energy systems. The working principle, methodology of product design and return on investment (ROI) analysis are discussed. Summarizing the same, an optimum technology is recommended for specific applications under given conditions.
