Thermal energy storage system using phase change materials: Constant heat source
Reddy Meenakshi R., Nallusamy N., Prasad Anjaneya B., Reddy Hemachandra K.
The usage of phase change materials (PCM) to store the heat in the form of
latent heat is increased, because large quantity of thermal energy is stored
in smaller volumes. In the present experimental investigation paraffin and
stearic acid are employed as PCMs in thermal energy storage (TES) system to
store the heat as sensible and latent heat also. A constant heat source is
used to supply heat transfer fluid (HTF) at constant temperature to the TES
system. In the TES system PCMs are stored in the form of spherical capsules
of 38 mm diameter made of high density poly ethylene (HDPE). The results of
the investigation are related to the charging time and recovery of stored
energy from the TES system.
