This study presents an entropy analysis of the losses in different sections of a central air conditioner. The methodology for determining the losses using entropy analysis is presented in this work. The temperature and humidity of the outside and recirculating air were measured, and losses due to mixing of air flows, cooling in the evaporator section, and heating in the condenser section were calculated. A comparative analysis of the results was performed, and the distribution diagrams of the component losses were presented. Conclusions regarding a loss-reduction method were proposed.
