Air-cooled constant temperature & constant pressure chiller control system
Developed independently by NUOLAN, this system is specifically designed for the semiconductor chip manufacturing industry, primarily for cooling and supplying water to chip production equipment. The constant pressure water supply unit automatically maintains a constant pressure 24 hours a day. It adjusts the water pressure continuously and steplessly based on pressure signals, ensuring both constant supply pressure and constant supply temperature. The pressure regulation is smooth, reducing impact on the motor and pump, thereby extending their service life and avoiding the water hammer effect commonly seen in traditional water supply systems.
The variable frequency constant pressure system features comprehensive protection functions and reliable operation, including under-voltage, over-voltage, over-current, and over-temperature protection. The system configuration supports fully automatic timed water supply, enabling unattended operation. The PLC programming and color touchscreen control panel provide fault alarm and display functions, and allow manual/automatic frequency conversion switching for emergency water supply. The system adjusts pump speed according to real-time water demand, keeping the pump operating within its high-efficiency zone. When the system reaches zero flow, the unit enters standby mode, and the pump stops; it resumes operation only when flow increases. This results in significant energy savings, reducing power consumption by 23%–55% compared to constant-speed pumps. The variable frequency constant pressure water supply unit eliminates the need for rooftop water tanks, reducing building construction costs while preventing secondary water contamination. The entire unit is integrated into a compact cabinet, offering a sleek appearance, easy installation, and minimal footprint. With fully automatic control, operators simply start or stop the unit to achieve the desired operating conditions. The system is extremely user-friendly.
