| Abstract: | A model of the exergetic analysis of a chill storage-based central air conditioning system is established. In order to compare the above system with a normal one, the exergetic efficiencies of both systems are calculated. The weakness of this system lies in the significant exergetic loss during the ice-melting process. We find that lowering the temperature of supply and return water during the ice-melting process and optimizing the design of heat exchanger can improve the exergetic efficiency. A central air conditioning system run by chill storage features has both economic benefit and high exergetic efficiency. |
| Keywords: | central air conditioning chill storage exergetic effciency |
