AI Technical Summary

Technical Problem

The heat exchanger of the existing constant temperature environment automatic titration calorimeter uses open-loop control, which makes it difficult to control the temperature accurately, resulting in temperature overshoot or insufficient reflux. It also makes it impossible to achieve continuous measurement, and the data from each titration is saved in segments, which limits its application in thermodynamic research.

Method used

A closed-loop feedback control system is adopted, which monitors the temperature of the reaction system in real time through the temperature monitoring unit, collects the temperature baseline value, and actively performs heat exchange after the titration reaction is completed to ensure that the reaction system returns to the baseline value range. A closed-loop feedback control system consisting of a heat exchange unit, a temperature monitoring unit, and a control unit is constructed.

Benefits of technology

It enables continuous measurement during continuous titration, eliminates the problems of temperature overshoot and insufficient reflux, ensures that each titration is carried out under the same temperature conditions, improves the degree of automation and data continuity, and provides a more accurate experimental method.

Abstract

The invention discloses a heat exchange controller, system and method for dripping heat, electronic equipment and a storage medium. The heat exchange controller comprises a heat exchange unit; a temperature monitoring unit; the control unit is electrically connected with the heat exchange unit and the temperature monitoring unit, and the control unit is used for continuously monitoring the temperature of the reaction system through the temperature monitoring unit and repeatedly executing the following operation until a preset end condition is met; the temperature baseline value is the temperature value of the reaction system in a heat balance state before titration operation; after the temperature baseline value is acquired, titration operation is executed, and titration reaction is carried out; under the condition that the titration reaction is finished, starting a heat exchange unit, and carrying out heat exchange on the reaction system; and controlling the heat exchange unit to stop heat exchange under the condition that the temperature of the reaction system is recovered to be within the threshold range taking the temperature baseline value as the reference, namely the reaction system is in a quasi isothermal state.
