Phase change storage(PCS) system added into the cold storage can stabilize the temperature of the cold storage
extend the preservation time
and achieve a good economical efficiency combined with the peak-valley price. Storage boards were installed as a test system in an incubator
which are filled with water
and the volume ratio between the PCM and the incubator is 1:30. By analyzing the insulation effect
the temperature distribution and the temperature difference between the PCM and air
the experimental data showed that the cold storage with phase change storage system had a temperature fluctuation of 0.6℃ and the maximum temperature difference is 1.1℃
so it can satisfy food fresh-keeping demands and achieve good economical efficiency. This result is important for the phase change storage system to be used in the cold storage.
