Patent ID: 8668380

Claim:
A method for operating a calorimeter comprising a reactor for receiving a reaction medium, a reactor jacket, an in-reactor heater controlled by a first controller, an outer temperature control unit in thermal contact with the reactor and controlled by a second controller, and a measurement sensor arranged in the reactor, the method comprising the steps of: setting a set-point temperature for the reactor and entering the reactor set-point temperature into the first controller; determining a reactor temperature using the measurement sensor and determining a deviation of the reactor temperature from the reactor set-point temperature as a control deviation of the first controller, the reactor temperature being controlled by the heat delivered to the reactor by at least one of the in-reactor heater and the outer temperature control unit and by the heat taken away from the reactor by the outer temperature control unit; splitting the determined control deviation into first and second parts, and dynamically adjusting the power, to compensate for the control deviation, through the substeps of: delivering the first part as heat to the reactor by the in-reactor heater, and entering the first and second parts into the second controller for controlling the outer temperature control unit, and adjusting the reactor temperature to the reactor set-point temperature as a result of the heat carried into and/or out of the reactor.
