Energy Efficient Dormitory by Retrofitting the Heat Pump Water Heating System in a University Campus
With cost of energy rising,value of conservation grows.Interest in energy efficiency could be a sound investment or a necessary public policy.Heat pump systems provide economical alternatives of recovering heat from different sources for use in various applications.The objective of this study is to present the strategic approach on energy efficient analysis of the water heating system retrofitted by applying a heat pump system in the dormitory of a university.Energy savings were determined by comparing field measurements of water consumption,water temperature and power consumption of overall system before(electric resistance heating system)and after(heat pump heating system)implementation of this project.Furthermore,building energy simulation code(eQuest)has been applied to verify and predict the long term energy consumption for both of the water heating systems.The results from energy modelling revealed the good agreement for energy simulation and field measurement data and the improvement of energy efficiency and energy savings could be achieved satisfactorily by retrofitting of heat pump system.The energy conversion efficiency of hot water for energy consumption at 0.63(Mcal/Mcal)could be achieved after the application of heat pump water heating system.It also presented the annual saving about US$ 20,000(NT$ 600,000)for the dorm by using heat pump heating system under the electrical billing rate of Taiwan.
