Summary: | The article presents numerical analysis of exergy for air-conditioning influenced by ambient temperature. The
model of numerical simulation uses an integrated air conditioning system exposed in varied ambient temperature to
observe change of the four main devices, the compressor, the condenser, the capillary, and the evaporator in
correspondence to ambient temperature. The analysis devices of the four devices’s exergy influenced by the varied
ambient temperature and found that the capillary has unusual increasing exergy loss vs. increasing ambient
temperature in comparison to the other devices. The result shows that reducing exergy loss of the capillary influenced
by the ambient temperature is the key for improving working efficiency of an air-conditioning system when influence
of the ambient temperature is considered. The higher ambient temperature causes the larger pressure drop of capillary
and more exergy loss. |
