The Nuobing integrated water-cooled chiller has been widely used in the fields of pharmaceutical, purification air conditioning, food, chemical and other process freezing and refrigeration air conditioning. It has a large number of successful cases and has won the favor and recommendation of customerschangewater-coolingtypeThe chiller unit mainly has the following characteristics.

1 Efficient integration and energy-saving of the system, outdoor rainproof design without the need for a computer room

wholeIntegrated water-cooled chiller unitBy optimizing the refrigeration system components, efficient integration of unit system components, water pumps, and cooling towers can be achieved, maximizing perfect system integration and energy saving. It can save more than 30% energy compared to air-cooled units and more than 20% energy compared to ordinary water-cooled units. The whole machine is designed to be rainproof and can be directly placed outdoors without the need for a dedicated computer room, saving the construction cost of the computer room;

2 Integrated implementation of optimal matching unit modularization

With energy-saving centralized control and system integration as the core, through the interconnection and relatively independent integration of multiple modules, centralized control and energy-saving are achieved, and each module realizes its own automatic operation and space requirements, greatly realizing the convenience of overall integrated system operation, maintenance, disassembly and other management and use.

3 ProgrammablePLCControl, just one click start, the entire refrigeration system achieves fully automated operation

The integrated water-cooled chiller unit enables remote and on-site one click shutdown, start-up, and related program operation. After start-up, the entire refrigeration system is fully automated according to the refrigeration load, and each system component (host, water pump, water tower) is automatically linked, communicated, controlled, and coordinated for operation;

4 Industrial grade high-end and high standard design

Adopting high configuration and optimal system integration to cast high-quality products, our professional team designs according to industrial standards, with low noise and minimal vibration. Designed according to industrial standards, we are suitable for uninterrupted operation 24/7 throughout the year24Running for hours.

6Compact structure, superior performance, stable operation

Using high-quality imported twin-screw bearings, whose moving parts are only for piston compressors1/10Vibration is only present in piston compressors1/5Both radial and axial use high-precision GermanFAGAnd SwedenSKFBearing combination, combined with axial thrust balance drum, effectively balances axial load, with a failure rate only comparable to that of piston compressors1/10Combined with world-renowned control components, it ensures the long-term safe and stable operation of the unit.Integrated water-cooled chiller unitThe condenser and dry evaporator both use high-efficiency heat transfer tubes, and the main engine adopts imported high-efficiency semi enclosed twin-screw compressors, which have many advantages such as compact structure, small volume, light weight, and small installation position. The semi closed twin-screw compressor has fewer moving parts, and the compressor adopts5：6Ultra efficient screw rotor, with no direct wear between rotors and high reliability. Due to the fact that screw machines are continuous compressors without pulsation, integrated water-cooled chillers have the characteristics of stable performance, low noise, small vibration, and smooth operation. Improved efficiency compared to reciprocating compressors20%—30%, has been obtainedIS09001International quality certification and patents from multiple European and American countries;

7A comprehensive energy control system

The integrated water-cooled chiller unit single compressor has a four stage and stepless capacity control system, energy regulation:[100、75、50、25(or activated,0Automatically adjust the start and stop of the unit according to load changes, which is more energy-efficient. During operation, the computer control system will adjust the energy output of the unit based on changes in the client's thermal load. The microcomputer quickly determines and sends a signal to push the slide valve to the required energy by monitoring the difference between the actual load measured and the user's setting. And in multiple systems, working in an optimized way that minimizes energy consumption with the best cooling output not only demonstrates excellent performance at full load, but also has high operating efficiency even at partial load;

8The refrigeration system operates independently

Large capacity integrated water-cooled chillers have two or more independent refrigeration circuits, even if one circuit fails/Maintenance, the other circuit can also operate normally. Equipped with backup function, especially suitable for industrial non-stop environments; ImportPLCThe human-machine interface is a LCD touch screen with graphical display, easy to operate, and available in both Chinese and English. ProvidedRS485National standard communication interface, compatible withDCSThe system is connected and can be connected to the entire factory automation network for remote control and monitoring. It is displayed in two ways: graphical and textual table parameters, which are clear at a glance;, Select the operation according to the menu on the screen, and simply touch the display button on the screen with your finger.

9Programmable microcomputerPLCMultiple protection functions of the controller

Equipped with protection against high compressor coil temperature, timed oil preheating and power on/off, cold water flow switch, and protection against low cold water outlet temperatureY- △ Start failure protection and troubleshooting Protection functions such as high gas temperature protection, compressor overload protection, power-off memory function, frequent start stop protection, abnormal voltage protection, low oil level protection, high and low voltage protection, etc;

10Multiple protections, safe, reliable, and stable

Provide comprehensive protection from refrigeration system, electrical system to water system, fully ensuring the safe and normal operation of integrated water-cooled chillers. Equipped with safety protections such as compressor motor overheating, overcurrent, abnormal phase sequence, high exhaust temperature, high pressure, low pressure, low pressure difference, freezing point, and interruption, as well as pressure control devices for the refrigeration system, the unit can operate without fail; In addition to the internal protection module of the compressor providing functions such as overvoltage, undervoltage, phase loss, and overload protection, the pressure control device of the refrigeration system can ensure that the unit works perfectly;

11Easy to install and run in a timely manner

Industrial grade specialized testing platform guaranteeproveIntegrated water-cooled chiller unitAll component installations, debugging and testing under different operating conditions have been completed in the factory to ensure that each device100%Qualified factory,And refrigerant and refrigeration oil have been added, users only need to connect the waterway and circuit to put it into use, greatly reducing on-site installation and debugging time;

12. Greatly save labor costs

Due to the integrated design of the overall refrigeration system, the entire refrigeration system only requires one click shutdown and start-up operation, fully automated operation, intelligent automation monitoring of the overall system operation, animated display of the monitoring unit operation status, and fully unmanned management operation. Only 1-2 people are needed to achieve the normal operation of multiple refrigeration systems in the factory, greatly saving labor costs.
