Abstract This manuscript has been presented to evaluate the annual performance of evacuated tube solar air collector (ETSAC) by using phase change material (PCM). The PCM (acetamide) simultaneously stores and exchange the heat to the air amid day hours. The heat stored by the PCM has been used to deliver hot air amid night hours. The performance of the system has been analyzed with a circular fin configuration along with reflectors at 0.035 kg/s air flowrate for 12 typical days. The performance of the system has been found excellent in the month of July. The maximum average temperature of PCM has been found to be as 87.8 °C and the maximum average collector efficiency as 31.4%.

In the hybrid coolingsolar systems , a solar collectoris used to convertsolar energy intoheat sourcein order to super heat therefrigerant leave thecompressor,andthisprocess helpsin the transformation ofrefrigerant state from gaseous statetothe liquid statein upper two-thirdsof thecondenserinstead of the lower two-thirdssuchas in thetraditional air-conditioning systems and this willreduce theenergyneeded torun the process ofcooling.In this research two hybrid air-conditioning system with an evacuated tube solar collector were used, therefrigerant was R22 and the capacity was 2 tons each.The tilt angle of the evacuated tube solar collector was changed and the solar collector fluid was replaced into oil instead of water.A comparison wasin the amount ofcurrentconsumptionof the two systems at the same operating conditions.The currentconsumptionof the hybrid coolingsystemwith the changed tilt angle and replaced fluid wasless thantheunchanged oneby(38% - 58%), meaning that there was a current consumption saving as a result of tubes tilt angle and solar collector fluid changing.
