The present work is an experimental study in to thermal performance of air conditioning system (split unit) bases on solar assisting technique. The SERPANTINE FLATE PLATE SOLAR COLLECTOR (SFPSC) is combined with a 1-ton capacity split air conditioning system, which is installed after the compressor to superheat the refrigerant that leaves the compressor. With the conventional air conditioning SYSTEM. THE RESULT SHOW That THE coefficient of performance (COP) of the solar assisted air conditioning system (SAAC), is affected by the enhancement of the solar collector, which enrolls the effect of solar collector tilt angle. The results show that the COP of SAAC is boosted by about 31.5% more than the conventional system t tilt angle 13.5o. <br /><br /><br />
