The paper builds exergy equations of each component of the chiller, and with a practical project, the total exergy loss and efficiency in different modes are calculated based on the equations. The energy saving effect is shown in aspect of energy quality by comparing and analyzing the calculating results, which show the exergy efficiency rise to 43.5% from 38.1%. Besides, energy consumptions in different hot-water-producing methods, which include gas-fired boiler and electric boiler systems, are analyzed based on a practical project to display the energy saving benefits of recovery heat application, which gets an energy saving ratio over 90%.
