Investigation of White Vaseline as an alternative phase change material for thermal regulation of physiological birth rooms

This research work encompassed the results of experimentation an innovative composite (Plaster/white Vaseline) for indoor thermal regulation physiological birth rooms using Latent Heat Thermal Energy Storage (LHTES) concept. The temperatures these specific sanitary need to be continually stabilized approximately at 35 °C. Accordingly, white Vaseline (petroleum jelly) was recovered from health facilities and then tested as alternative PCM a LHTES application constant temperatures. petroleum jelly used in this is mainly composed microcrystalline wax liquid paraffin; its phase change were found respectively 36.56 °C 35.53 melting solidification cycles with enthalpy value 95.38 J/g (±1.23). In addition suitable properties, substance safe available low-cost. A mineral matrix prepared essentially plaster experimented trap into microstructure order prevent any risk leakage during process . Finally, underwent physico-chemical characterization tests that identified properties revealed potential efficiency novel material passive room's environments. • White investigated rooms. successfully trapped panel. conductivity composite-PCM enhanced by granulated graphene. could efficient temperature stabilization
