Temperature Feedback Control System

Contact us today for the perfect temperature control solution

 

The temperature feedback control system is dedicated to constant temperature control of external loads. It adopts a sealed design. At high temperatures, oil mist and pungent odors will not be evaporated into the environment. At low temperatures, impurities and moisture in the ambient air will not be absorbed. Only the heat-conducting medium participates in circulation and expansion. The temperature of the tank is always kept at a low temperature, which avoids many problems such as deterioration of the circulating medium and unfriendly environment caused by air entering the circulation system.

Design analysis of temperature feedback control system:

1. Temperature demand analysis: First, it is necessary to clarify the temperature range and accuracy required to be controlled to determine the design goals of the entire system. Different application scenarios may have different temperature requirements, such as laboratories, industrial production lines, or residences.

2. Select appropriate refrigeration and heating equipment: Select appropriate refrigeration and heating equipment according to temperature requirements. Refrigeration equipment usually includes components such as compressors, evaporators, condensers, and expansion valves, while heating equipment may use electric heaters, electromagnetic heaters, or gas heaters.

3. System layout design: Design the layout of refrigeration and heating equipment according to actual needs. Reasonable layout can optimize the performance of the system and improve the stability of temperature control. Considering the heat dissipation problem, refrigeration equipment is usually placed in a well-ventilated area.

4. Control system design: Design the control system to achieve accurate temperature control and stability. Common control strategies include proportional-integral-derivative (PID) control, fuzzy logic control or model predictive control. The temperature is monitored in real time through sensors, and the working status of the refrigeration and heating equipment is adjusted based on the feedback signal to keep the temperature within the target range.

5. Safety protection measures: In order to prevent malfunctions or abnormal conditions such as overtemperature and overpressure during system operation, corresponding safety protection measures are designed. For example, install pressure switches, temperature switches and alarm systems, and set up emergency stop buttons, etc.

6. Energy consumption analysis and optimization: Evaluate and optimize energy consumption. Reasonable selection of refrigerants and heating methods, optimization of equipment operating parameters, and adoption of energy-saving measures, such as waste heat recovery, can reduce energy consumption and improve system efficiency.

7. Maintenance plan and operation management: Establish a systematic maintenance plan, including regular cleaning, equipment maintenance and replacement of key components. At the same time, establish system operation and management specifications to ensure that equipment operators have relevant skills and safety awareness.

The design analysis of the temperature feedback control system involves temperature demand analysis, selection of appropriate equipment, system layout design, control system design, safety protection measures, energy consumption analysis and optimization, as well as maintenance planning and operation management.
