In this work, a combination between latent heat storage materials (LHSm) and sensibleheat storage materials (SHSm) as new storage heat material in flat plate solar air heater wastested experimentally. PCM (paraffin wax) at a certain ratios (10%) and (20%) were used asLHSm with a pure cement (base material) as SHSm. The experimental tests was doneindoor at irradiance of (1000W/m2) with forced convection, the mass flow rate of air are(0.5kg/min) and (1.13kg/min). The results indicated that the enhancing thermo-physicalproperties of adding pure cement by a certain ratios of paraffin wax led to enhancement inthermal energy stored. The percentage increasing in storage heat duration time was (29%)for compound cement with (10%PCM), (38.4%) for compound cement with (20%PCM),compared with pure cement at (0.5kg/min) air mass flow rate. And at (1.13kg/min) air massflow rate, it was (33.3%) for compound cement with (10%PCM) and (52.6%) for compoundcement with (20%PCM) compared with pure cement.
