Abstract

The application of electric water heater in residential and commercial buildings is quite familiar to be heard due to the increasing occupant’s demands. However, the high consumption of energy and electricity charges on generating hot water through electric water heater is continuously burdening to the most people because of the application is widely used especially by the residential and industrial. In the other hand, air conditioner is well known as provider of cool air to the targeted region but not everyone know that it simultaneously release a hot air to the atmosphere from the outdoor unit. This is basically the refrigerant cycle but not everyone knows the fact that the waste heat energy harvested from the outdoor unit can be beneficial to other applications. The fabrication and testing done on this project leads to the production of free hot water in using harvested heat energy from outdoor unit of air-conditioner. The result shows the increment of COP of modified unit and even more economical than normal unit. The conclusion is harvested waste heat from outdoor unit had proved it capabilities in generating hot water in economical ways. The utilization of waste heat could be dominant in the future where the conservation of energy been fully applied. Therefore, this project is about investigation of energy and cost effectiveness between electric water heater and energy harvested from 1.0 HP air conditioner.
