Summary

The use of secondary refrigeration can reduce cooling system impact on environment by greenhouse gas reduction, nevertheless this kind of technology reduce the system efficiency. The use of high energetic density and thermal energy storage was considered to improve system efficiency and to answer to industrial cooling process issue (air-conditioning, cooling process or temperature preservation). An experimental set-up composed by a stired tank reactor and circulation loop was used in order to evaluate the charging and discharging dynamic of a cooling district using phase change slurry. This experimental study offers the opportunity to elaborate and validate further models (stirred tank reactor, heat exchanger, flow behavior) to predict the charging and discharging behaviors for various storage materials. Then, these models were used in the case of an industrial system to observe the impact of the storage material or system sizing, energy consumption and economic sustainability. Thus, results show that the impact of the storage device on system energy efficiency and the return on investment depends on storage scenarios. Finally the impact of the chosen material on system efficiency was pointed out.
