| Abstract: | The mechanism of vacuum cooling was analyzed in the case of insulation.A simple mathematical model of the vacuum cooling process was developed to predict a temperature evolution and the variations of temperature during the process of vacuum cooling.Experimental system of vacuum cooling is set up to test and verify the model.The results showed the predicted temperature variations agreed with the experimental date well. |
