The objective of the present paper is to investigate the condenser heat recovery in water-cooled chiller system. According to the technology characteristics of vapor compression refrigerating cycle, the viewpoint of condensing heat reclaim was proposed, and heat recovery system can be used in buildings. Air-cooled and water-cooled chillers with heat reclaim capability were discussed. Three optimized water system designs were introduced for more heat recovery or higher heating water temperature. The results show that it is very useful for designing and developing the new heat recovery unit with high efficiency, energy conservation, and environmental protection by analyzing the feature feasibility of condenser heat recovery system. The control of entering-condenser water temperature is recommended for higher chiller efficiency and operating steadily, the water system designs of preferential loading and side stream are for more heat recovery.
