Thermal energy storage (TES) systems are growing to a relevant role in solar cooling applications. Hence,
high energy density is a desirable property of the TES system. Phase change materials (PCM) helps to
increase this characteristic. A high temperature pilot plant able to test different types of TES systems and
materials was designed and built at the University of Lleida (Spain). This pilot plant is composed mainly
of three parts: heating system, cooling system, and different storage tanks. Two identical storage tanks
based on the shell-and-tubes heat exchanger, one of them including 196 squared fins in the bundle of the
tubes and the other without, were experimentally tested. Hydroquinone was selected as the storage
material, having a latent heat of 205 kJ/kg and a phase change temperature between 168 and 173 C. The
aim of this paper is to test experimentally, and compare the average effectiveness of the TES systems
analyzed using PCM for solar cooling and refrigeration applications. It was found out that for the same
tank configurations (shell-and-tubes) even changing drastically the dimensions of the tank or the
number and the diameter of the tubes, the average effectiveness curve proposed in the literature fits well
with the results showed here. |
