1、 Structure

It usually consists of three main parts: a refrigeration and heating unit, a heat transfer medium circulation system, and an intelligent control system. The refrigeration and heating unit works in conjunction with the compressor and electric heater to achieve wide temperature range control. The high-temperature and high-pressure refrigerant discharged from the compressor is liquefied by the condenser, and after being throttled by the expansion valve, it absorbs heat in the evaporator, reducing the temperature of the heat transfer medium; Electric heaters use a pipeline heating structure to accurately raise the temperature of the conductive medium. The thermal conductive medium circulation system adopts a fully enclosed pipeline design, and the expansion container is insulated from the circulation circuit to avoid oxidation or water absorption of the medium in contact with air, ensuring long-term operational stability. The intelligent control system adopts advanced control algorithms, such as the combination of PID algorithm and fuzzy control technology, and adjusts control parameters in real time through three-point sampling of material temperature points and temperature control system inlet and outlet temperatures.

2、 Function

The core function of the TCU temperature control unit is to accurately control the temperature of the process medium through a cooling or heating cycle system. It can achieve various functions such as heating, cooling, circulation, and temperature feedback adjustment according to different process requirements. In practical applications, the working status of heating and cooling elements can be automatically adjusted based on preset temperature curves or real-time feedback temperature data, achieving precise temperature control. In addition, it also has the ability to quickly raise and lower the temperature, which can adjust the ambient temperature to the set value in a short period of time, effectively shorten the heating or cooling time, and improve production efficiency.
