The use of the ice slurry is recently applied in the refrigeration and air conditioning systems. Advantages such as the possibility to store latent heat on ice and the possibility of being pumped as cold water can be considered. Ice slurries can be used both for cold storage in place of chilled water or ice and as a secondary refrigerant since, up to certain concentrations, they can be pumped directly through distribution pipeworks and heat exchangers. For ice slurries to become more widely accepted, however, more engineering information is required on fluid flow and heat transfer characteristics. An experimental device was developed to study the transport properties of the ice slurry in plate heat exchangers. Several situations were investigated for different initial fractions and flows of ice slurry. The conditions of the thermal load (pure water), had been kept constant. The temperature field, the pressure loss, the initial fraction and the flow of ice slurry are monitored in the heat exchanger, beyond the flow and the temperature field is monitored in the part of the thermal load. The overall heat transfer coefficient, increases in function of the initial ice fraction. The capacity cooling of the heat exchanger increases with the use of ice slurry when compared to pure water. Finally can be showed that the loss of pressure increases for higher initial ice fraction.
