| Abstract | ||
| In this work, a combination between latent heat storage materials (LHSm) and sensible heat storage materials (SHSm) as new storage heat material in flat plate solar air heater was tested experimentally. PCM (paraffin wax) at a certain ratios (10%) and (20%) were used as LHSm with a pure cement (base material) as SHSm. The experimental tests was done indoor 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-physical properties of adding pure cement by a certain ratios of paraffin wax led to enhancement in thermal 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 mass flow rate, it was (33.3%) for compound cement with (10%PCM) and (52.6%) for compound cement with (20%PCM) compared with pure cement. | ||
