PROBLEM TO BE SOLVED: To provide an estimating device capable of precisely estimating temperature of an outlet gas of a water-cooling type gas cooling device which changes dynamically.SOLUTION: An estimating device calculates a current value of an inner temperature of a cooling device from each current value of an inlet gas temperature and an outlet gas temperature using a predetermined definition formula related to the inner temperature. Next, a current value of a heat radiation amount is calculated from each current value of inner temperature and coolant water temperature using a calculation formula of the heat radiation amount. Next, a next value of a ratio of an outlet pressure and the inner temperature is calculated from each current value of an inflow gas flow rate and an outflow gas flow rate using a flow rate conservation formula. A next value of the outlet pressure is calculated from each current value of the inflow gas flow rate, the outflow gas flow rate, the outlet gas temperature, the inlet gas temperature and the heat radiation amount using an energy conservation formula. Further, a next value of the outlet gas temperature is calculated from each next value of the ratio of the outlet pressure and the inner temperature, the outlet pressure and the inlet gas temperature using the definition formula. |
