Mathematical Analysis of Energy and Exergy loss in Air Conditioning system as Affected by Ambient Temperature
Downloads
The article provides a Mathematical analysis of exergy in air-conditioning as affected by ambient temperature. The Mathematical simulation model employs an integrated air conditioning system subjected to varying ambient temperatures to monitor the changes in the four primary components: the compressor, condenser, capillary, and evaporator, in relation to ambient temperature. The examination of the exergy of the four devices revealed that the capillary exhibits an anomalous increase in exergy loss with rising ambient temperature, in contrast to the other devices. The findings indicate that minimizing exergy loss in the capillary, affected by ambient temperature, is crucial for enhancing the operational efficiency of an air-conditioning system when accounting for ambient temperature effects. The elevated ambient temperature results in a greater pressure drop in the capillary and increased exergy loss.
