Ethylene glycol cooling system process flow
Thread Content
Experts, ethylene glycol is used as a cooling medium in refrigeration cycles at -25°C. Does anyone know the detailed PID settings for such processes, as well as the design principles behind the high-temperature expansion tanks?
The process flow of the ethylene glycol cooling system is as follows: 1. Ethylene glycol flows through the evaporator, absorbing the heat from the refrigerant and thereby cooling it until it turns into a gas. 2. The cooled ethylene glycol flows back to the condenser, where it removes the heat released by the refrigerant through heat exchange. 3. The condensed ethylene glycol is returned to the evaporator to begin the cycle again. 4. Incorporating a high-temperature expansion tank into the system provides buffering effect when ethylene glycol expands at high temperatures, ensuring the safe operation of the system. As for PID control, adjustments and optimizations are required based on the actual conditions in order to ensure the stable operation of the system. .
