Abstract Briefly described in evaporative cooling and mechanical plex
system based on exergy analysis. And analysis the high-temperature pound
with evaporative cooling and mechanical refrigeration through exergy. It was based on
actual test data to calculation the size of exergy about import and export of evaporative
cooling and mechanical refrigeration. Finally get the exergy -efficiency and exergy
-effective of high-temperature chillers through exergy - analysis of plex system.
From perspective of exergy -efficiency parative analysis how to affect the
performance of air source heat pump through pre-cooling condenser by using evaporative
cooling . And finally proposed energy-saving improvements.
Keywords evaporative cooling, high-temperature chillers, exergy analysis, exergy
