Abstract:

PROBLEM TO BE SOLVED: To provide a reduction quantity calculation system, reduction quantity calculation device, thermistor calibration device and calibration method capable of improving temperature detection accuracy while restricting cost.SOLUTION: A reduction quantity calculation system 1 comprises: a reduction quantity calculation part 54g for calculating a reduction calory on the basis of electrical signals from a first thermistor 51, a second thermistor 52, and a flow rate sensor 53; a relative data memory part 54e storing relative data indicating relation between an output value and a temperature of each of the thermistors; and a calibration data memory part 54f storing a relational expression in which an output value of each of the thermistors is applied as a variable value and a difference value varies continuously. The reduction quantity calculation part 54g calculates the difference value in view of the output value indicated by the electrical signals from the first thermistor 51 and the second thermistor 52 and the relational expression stored in the calibration data memory part 54f, adds the calculated difference value to the output values indicated by the electrical signals, and attains a temperature in reference to the value obtained through addition and the relative data stored by the relative data memory part 54e.
