چکیده:

in this study, the effects of degrees of subcooled, number of rows and number of fins per inch on the COP and overall COP of split air conditioner out door unit are investigated for a fixed condenser facing surface area. The system is utilized with the scroll compressor, modeled based on thermodynamic and heat transfer equations employing Matlab software. The working refrigerant is R134a whose thermodynamic properties are called from Engineering Equation Software. This simulation shows that split air conditioner can be designed by different configurations and COPs. The optimum values of these parameters obtained via providing practical figures
