PERFORMANCE EVALUATION METHOD OF HEAT INSULATING CONTAINER AND COOLANT, PERFORMANCE EVALUATING APPARATUS UTILIZING THE METHOD, PROGRAM FOR USE OF THE PERFORMANCE EVALUATING APPARATUS, AND RECORDING MEDIUM IN WHICH THE PROGRAM IS RECORDED
PROBLEM TO BE SOLVED: To easily evaluate cold reserving performance or the like of a heat insulating container by a method other than temperature measurement.SOLUTION: A PTC heater 20 is disposed in a sealed heat insulating container 10 put in an environmental temperature to make the same carry electricity. A calorific value of the PTC heater 20 is calculated from an electric power value when power consumption of the PTC heater 20 has a stable value. The value is regarded as a theoretical effluent calorific value from the heat insulating container 10, thereby evaluating the cold reserving performance of the heat insulating container 10.
