Experimental study of short term thermal energy storage unit based on enclosed phase change material in polyethylene film bag

Experimental analysis of heat transfer characteristics of solar energy based latent heat storage system

“…The copper, aluminium and brass encapsulating materials are used in this study and the experimentation was done by changing different encapsulating material. During off sun shine hours the PTC was bypassed from the circuit, the cooled oil enters the storage tank and gets heated up by transferring heat from the PCM, Discharging process of PCM [8,9]. The inlet and outlet temperature of HTF in the PTC was recorded in order to calculate the thermal gain of the oil through PTC.…”

Thermal Energy Storage Using Phase Change Materials

“…The use of flexible thin film packaging reduces issues with ullage space contraction as the thin film is flexible enough to accommodate the volume change For instance, polyethylene thin film packaging was used to contain paraffin for energy storage in an under-floor ventilation duct system with the intention of reducing building energy consumption [27].

Numerical investigation of free-cooling system using plate type PCM storage

“…Turnpenny et al [20] tested cylindrical geometry of heat pipes to achieve free-cooling. The results showed that with this geometry a 15°C difference of temperature between air and PCM was needed to have melting times shorter than 10 h. And with a temperature difference of 5°C, the heat transfer rate was approximately 40 W over a melt period of 19 h. Zukowski [21] tested with plastic bags containing PCM with 10°C difference to charge the system in 3 h.…”
