Abstract：
Presents a novel type of heat pump type CCHP system using the absorption chiller as heat pump in winter, thereby energy efficiency of the system can be improved and the operation cost reduced, while the initial cost would not be increased excessively except for a condensation heat exchanger. Through theoretical and practical research concludes that this kind of system can use the high quality natural gas energy adequately and improve the system comprehensive efficiency.
