Air Conditioning Systems from a 2nd Law Perspective

Air Conditioning Systems from a 2nd Law Perspective

In this paper exergy analysis is used to assess the performance of the three most common air conditioning plant schemes: all-air, dual-duct and fan-coil systems. The results are presented in terms of flow diagrams to provide a clear picture of the exergy flow across the systems. The most relevant ou...
