Analysis of Energy Saving in a Clean Room Air-conditioning System
MetadataShow full item record
To address the issue of the substantial energy cost and operating cost of an all-return air system for a clean room, we changed the former system to a 2nd return air system. With the newest building energy simulation program, Energy Plus, we simulated and compared the summer energy consuming conditions of the two systems. Results prove the superiority of the 2nd return air system, and the validity of the simulation. Also, the air system energy performance in summer was illustrated with typical meteorological hour-to-hour data.
