摘要：The work has been undertaken to experimentally study performance of heat pipe in latent heat thermalenergy storage (LHTES), with different working fluid fill ratio of heat pipe. Fill ratio is defined as the mass of workingfluid required to charge heat pipe for maximizing the rate of heat transfer. Heat pipe was designed for its application inLHTES and the performance of heat pipe was tested by varying heat pipe charging mass of working fluid against itsdesigned value. Designed value of heat pipe working fluid fill ratio depends on number of parameters, a numericalmodel designed to find fluid fill ratio. Experiment with flow rate of 10 lit./min. was conducted for different fill ratio of80%, 90%, 100%, 110% & 120% and charging discharging of LHTES was tested. With increasing mass of chargingfluid filled in heat pipe the rate of heat transfer increases but the evaporator temperature decreases. Significant effect ofdecreasing fill ratio is seen in charging and discharging process of heat pipe embedded LHTES. Drastic change indischarging time due to change in fill ratio and discharging time reduces by 40%. Heat transfer between heattransferring fluid (HTF) and phase change material (PCM) increases with decreasing fill ratio below design value butadverse effect of more charging is not much significant.
