Integrated Water-Cooled Chiller Unit

The Huahui integrated water-cooled chiller units have been widely applied in the fields of pharmaceuticals, purification air conditioning, food, chemical industry, and process refrigeration and air conditioning. With numerous successful cases, they have gained the favor and recommendation of a large number of customers. The main features of the Huahui integrated water-cooled chiller units include:

1. System integrates efficiently for energy saving, outdoor rainproof design, no need for machine room

The integrated water-cooled chiller system, with optimized refrigeration components, achieves an efficient integration of system components, pumps, and cooling towers, maximizing perfect system integration and energy saving. It is more than 30% more energy-efficient than air-cooled units and over 20% more efficient than standard water-cooled units. The whole unit is designed for rain protection, allowing direct outdoor placement without the need for a dedicated machine room, thus saving costs associated with machine room construction.

2. Integrated for optimal unit module matching

At the core of energy-saving centralized control and system integration, through interconnected and relatively independent integration of multiple modules, it achieves centralized control for energy saving and allows each module to run automatically according to space needs. This greatly enhances the convenience of system operation, maintenance, and disassembly management.

3. Programmable PLC control with one-touch start, enabling the entire refrigeration system to operate fully automatically

The integrated water-cooled refrigeration unit allows for remote and on-site one-button start-up and shutdown, along with program operations. Once powered on, the entire refrigeration system operates automatically based on the cooling load, with all system components (main unit, pump, water tower) automatically communicating, coordinating, and running in联动.

4. Industrial-grade high configuration and high-standard design

Utilizing high configuration and optimal system integration to cast high-quality products, our professional team designs with industrial-grade standards, ensuring low noise and minimal vibration. Engineered to industrial standards, our products are suitable for continuous, 24/7 operation throughout the year.

6. Compact structure, superior performance, and stable operation

Utilizing high-quality imported twin-screw bearings, the moving parts are only 1/10 of a reciprocating compressor, and the vibration is only 1/5. Radial and axial high-precision German FAG and Swedish SKF bearing combinations are employed, along with an axial thrust balancing drum, effectively balancing the axial load, with a failure rate just 1/10 of a reciprocating compressor. Combined with world-renowned control components, the unit ensures long-term safe and stable operation. The condenser and dry evaporator of the integrated water-cooled chiller unit both use high-efficiency heat transfer tubes. The main unit is equipped with an imported high-efficiency semi-hermetic twin-screw compressor, boasting compact structure, small size, light weight, and minimal installation space. The semi-hermetic twin-screw compressor has fewer moving parts, uses a 5:6 ultra-high-efficiency screw rotor, with no direct wear between rotors, and high reliability. As the screw compressor is a continuous unit without pulsations, the integrated water-cooled chiller unit features stable performance, low noise, minimal vibration, and smooth operation. It improves efficiency by 20% to 30% compared to reciprocating compressors and has obtained ISO 9001 international quality certification and patents in multiple countries in Europe and America.

7. Comprehensive Energy Control System

Integrated water-cooled chillers with single pressure machines feature a four-stage and variable capacity control system, energy regulation: [100, 75, 50, 25 (or start, 0%)], automatically adjusting the start and stop of the unit based on load changes for greater energy efficiency. During operation, the computer control system adjusts the energy output of the unit according to changes in the client's thermal load. The microcomputer quickly determines and sends signals to drive the throttle valve to the required energy by monitoring the difference between the actual load measured and the user's setting. Moreover, in multi-unit systems, it operates optimally by consuming the least amount of electricity while delivering the maximum cooling capacity, demonstrating excellent performance not only under full load but also under partial load, ensuring high operating efficiency.

8. The refrigeration system operates independently

The high-capacity integrated water-cooled chiller features two or more independent refrigeration circuits, ensuring that if one circuit fails/maintains, the other can still operate normally. It comes with a backup function, particularly suitable for industrial environments requiring continuous operation; the imported PLC human-machine interface is a liquid crystal touch screen with graphical display, easy to operate, with options for both Chinese and English. Equipped with an RS485 national standard communication interface, it can be connected to DCS systems and integrated into the entire factory's automated network, facilitating remote control and monitoring. It displays information in both graphical and tabular text formats, making it clear at a glance; operations are selected via the screen menu, and the display buttons are directly touched with a finger.

9. Microcomputer Programmable PLC Controller with Multiple Protection Features

Over-temperature protection for compressor coil, oil pre-heating timer on/off switch, cold water flow switch, low cold water outlet temperature protection, Y-△ start failure protection, exhaust temperature over-temperature protection, compressor overload protection, power failure memory function, frequent start/stop protection, abnormal voltage protection, low oil level protection, high/low pressure protection, etc.

10. Multi-layer protection, secure, reliable, and stable

Offer comprehensive protection for refrigeration, electrical, and water systems, ensuring the safe and normal operation of integrated water-cooled chillers. Equipped with safety protections such as compressor motor overheating, overcurrent, phase sequence anomaly, high exhaust temperature, high pressure, low pressure, low pressure difference, freezing point, and open circuit, the pressure control devices of the refrigeration system guarantee the unit operates flawlessly. In addition to the compressor's internal protection module offering over/under voltage, phase loss, and overload protection, the pressure control devices of the refrigeration system further ensure the unit operates without fail.

11. Easy to install and operate promptly

Industrial-grade dedicated testing platform ensures that all components of the integrated water-cooled chiller have been fully installed, operationally adjusted, and tested at the factory. This guarantees 100% qualification for each unit before shipment, and refrigerant and lubricating oil have been added. Users only need to connect the water and electrical circuits to put the equipment into use, significantly reducing on-site installation and commissioning time.

12. Significantly reduces labor costs

Due to the integrated design of the overall refrigeration system, the entire system can be started or stopped with a single button, operates fully automatically, and is monitored by intelligent automation to oversee the system's operation. Animated displays indicate the operational status of the units, allowing for unattended management and operation. Just 1-2 people can ensure the smooth operation of multiple refrigeration systems in a factory, significantly reducing labor costs.
