Otherwise, it is a meaningful attempt to study the improvement of supercooling and cycle stability of ternary eutectic system from the point of fluid viscosity and different nucleating agents added.
In addition to that, the evaporation temperatures in the eutectic system are so low, that even the compressors optimized for liquid injection are operating beyond the limits of the envelope.
The main role of this technique, called inoculation, is the reduction of super-cooling during solidification by an increase in the number of eutectic cells to avoid, graphite of super-cooling and carbide graphite in the metal matrix, and prevents solidification by metastable eutectic system to obtain the graphite A type.
In the case of the eutectic system, all of the components have a high thermal conductivity and so the conductivity of the baseline material is not affected.
Containers are available from 50 to 1400 litres capacity (chest and roll models), with silent refrigeration options ranging from Olivo's own manufactured Eutectic System to Cryogenics (manufactured dry ice) and, increasingly nowadays, the Siber System of injected liquid CO2 to special tanks inside the container which guarantees temperatures being held for 24 hours or longer.
Figure 2 shows the phase diagram of the Ni-C eutectic as a typical example of a metal-carbon eutectic system. The lowest temperature of the liquid phase is detected at the eutectic composition.
Manel Rodrigo, Marketing Manager, Direct Drive, comments: "The eutectic system offers an ideal, economical and environmentally friendly solution for a niche market, in particular daytime deliveries of frozen goods in urban areas.
Further the applicability of general charge reduction strategies for refrigerating plant with eutectic system is analyzed together with some aspects specific to low temperature systems.
Containers are available from 50 to 1400 litres capacity (chest and roll models) with silent refrigeration options from Olivo's own manufactured Eutectic System to Cryogenics (manufactured dry ice) and, increasingly nowadays, the Siber System of injected liquid C02 in special tanks in the top of the containers.
To achieve the right temperature configuration, a Frigoblock Eutectic system has been fitted in the rear compartment and a DL280 fan kit in the front compartment.
Such refrigerated bodies are usually built with an integrated refrigerating plant with eutectic system. The information and recommendations available from the previous studies are analyzed primarily considering their applicability in such system.
