Abstract Heat recovery application has been added on the centrifugal chiller which is mainly focus on cooling.
It could recover condensation heat for customer using instead of discharging into the atmosphere through cooling
tower which would caused heat pollution and energy waste. The analysis and research according to the chillers’
operation condition and its head pressure have been done in this text. The exergy analysis also has been done to
reflect integrated energy saving. All this could improve that select a reasonable heat recovery chiller should be
very important to energy saving and recycling.
