Document Type and Number:
WIPO Patent Application WO/2018/167954
Kind Code:
A1
Abstract:
A temperature estimation device (100) calculates a first estimation temperature (41A) of a reactor (3) on the basis of a reference estimation temperature (21A) given by a first delay time (T1) and the output from a temperature change amount calculation unit (3) given by a second delay time (T2); predicts a second temperature change amount (53A) of the reactor (3) during a prescribed period of time on the basis of the first estimation temperature (41A); and predicts a second estimation temperature (61A) of the reactor (3).
