A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...

Packed bed or rock bed is very commonly known thermal energy storage component for solar air heaters. The major concern for design of packed bed energy storage system is to maximize the heat transfer with minimum pressure drop or pumping power. Under the given operating conditions, system parameters could affect heat transfer and pressure drop in the bed considerably. An attempt has been made t...

In the present paper an attempt has been made to report simulated performance of a packed bed solar energy storage system. Performance of the system having large size storgae material elements has been evaluated as a function of system and operating parameters. In the present part of this paper, system performance w.r.t. temperature distribution in the bed, thermal energy stored and available e...

Packed bed units generally, represent the most suitable storage units for air heating solar systems. In these systems the storage unit receives the heat from the collector during the collection period and discharges the heat to the building at the retrieval process. A method for sizing of packedbed storage in an air heating system is represented. The design is based on the K-S curves, which hav...

This article presents the results of a study into a packed bed filled with ceramic bricks. The designed storage installation is supposed to become part of a heating system installed in a single-family house and eventually to be integrated with a concentrated solar collector adapted to climate conditions in Poland. The system's working medium is air. The investigated temperature ranges and air v...

Packed bed is generally recommended for attaching with solar air heater in order to store thermal energy of hot air. For designing such a system under the given system and operating parameters, it is required to predict performance of the system by using mathematical models. In the present paper an attempt has been made to discuss mathematical models reported in the literature for predicting th...
