ECU unit

ECU unit is a modular device that achieves automatic and precise control of terminal temperature. In the pharmaceutical and chemical industry, it utilizes existing public energy sources in factories, such as electricity, steam, cooling water, chilled water, and ultra-low temperature liquids. Through intermediate conversion units (heat exchangers), energy is controlled and orderly transmitted to end users (reaction vessels, crystallization vessels, drying equipment, and other devices that require temperature control) based on the calculation of the process by the control system.

The ECU unit consists of a microcontroller (MCU), memory (ROM, RAM), input/output interface (I/O), analog-to-digital converter (A/D), and large-scale integrated circuits such as shaping and driving.

ECU generally has fault self diagnosis and protection functions. When the system malfunctions, it can automatically record fault codes in RAM and use protective measures to read alternative programs from the inherent programs to maintain engine operation. At the same time, these fault information will be displayed on the dashboard and remain on, allowing the car owner to promptly detect the problem and take the car to a repair shop.

1、 Design features of ECU unit:

1. Closed constant pressure design: A single medium is in a closed system, and the thermal expansion and contraction of the medium are automatically adjusted through an expansion tank. The secondary heat transfer medium in the closed system does not come into contact with air, which can reduce the risk of oxidation, absorption of moisture, or volatilization of the heat transfer medium.

2. Energy saving design: Based on real-time data feedback from energy consumption points, accurately calculate the energy demand, optimize the comprehensive control mode of secondary medium flow and temperature, and achieve energy conservation while ensuring the accuracy of energy consumption point control.

3. Integrated disassembly and assembly: Modular design has been carried out, with each component integrated into the module with minimal clearance while ensuring safety, and standardized interfaces reserved.

4. Control technology: Based on this system, industrial fuzzy control technology with PID temperature control algorithm with feedforward is adopted, which can improve the temperature control accuracy to within ± 1 ℃ range.

2、 Product features:

1. Controllability: Achieve the required temperature for the reaction at a controllable temperature exchange rate.

2. Accuracy: Control the reaction to be carried out with high temperature precision.

3. Safety: Ensure that the entire reaction is completed in a safe state.

4. Formulation based: Implement formulation based management and unmanned operation during the unit production process.

5. Energy control accuracy and range:

One to one mode: control response accuracy can reach ± 0.5C

For multi-mode: the control reaction accuracy can reach ± 2.0 ℃

Under normal circumstances: -25/160 ℃

Under special circumstances: -80/220 ℃

3、 ECU is suitable for public energy:

Steam, electric water, ethylene glycol aqueous solution, any other liquid.
