ABSTRACT
The working principles of a window air conditioning system was described with the mode of operationg of the refrigeration cycle and its construcion. The aim of every window Air conditioning system is to achieve cooling. Change of temperature system were discussed with the methods of improving the performance of th window Air Conditioning Unit for better efficiency. This work simply explains how the performance of the window Air Conditioning system can be improved and why it is more economical to use the window air conditioning system than split Unit Air Conditioning system.
