Energy is one of the basic requirements for the existence and development of human life. The focus is now shifting to energy conservation due to the problems associated with conventional energy sources. This project introduces a novel water heater product that can achieve the multi-functions with improved energy performance. This paper deals with experimental investigations on the performance of a water heater, which uses waste heat from a 1.5 tonne air conditioner. Thus incorporation of a water heater in the outdoor unit of a split-type air-conditioner would result in simultaneous room space cooling and water heating. The experimental results showed that the water heater is capable of producing 88 litres of hot water in one hour of time with a temperature of 52°C. It is seen that up to 37°C of hot water temperature, COP of the waste heat recovery system is more than the COP of conventional air conditioner. But after 37°C, with the increase in hot water temperature, the COP of the waste heat recovery system decreases and becomes less than the COP of conventional air conditioner.Keywords

The big challenge of the nation is the rising demand for power. The solution is to not just increase investment and enhance power generation, which is a prime need anyways, but invest in more efficient power distribution and optimize power consumption through use of efficient technology. An important component of power consumption worldwide is lightning. India is no different. Global trends in outdoor lighting shows that 18-38% of the total energy bill goes towards outdoor lighting and therefore this is one domain that needs major attention if we look at improving efficiency of power consumption with an objective of saving energy. T5 tube lights with electronic ballast are the best available fluorescent tube light options in the market. A T8 tube light with electromagnetic ballast typically consumes 38W of electricity but a T5 with electronic ballast will consume only 28W of electricity. Thus a T5 provides about 26% electricity saving over a regular T8tubelight. The audit on (68 No’s) T8 tube lights versus T5 tube lights has been done based on the total energy consumption, replacement cost, annual cost saving and payback period.
