Integrated water-cooled chiller unit
Huihui integrated water-cooled chillers have been widely used in the fields of pharmaceutical, purification air conditioning, food, chemical and other process refrigeration and refrigeration air conditioning. They have a large number of successful cases and have won the favor and recommendation of customers. Huihui integrated water-cooled chillers mainly have the following characteristics.
1. Efficient integration and energy-saving of the system, outdoor rainproof design without the need for a computer room
The integrated water-cooled chiller unit, combined with optimized refrigeration system components, achieves efficient integration of unit system components, water pumps, and cooling towers, achieving maximum system integration and energy saving. It saves 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 directly placed outdoors, without the need for a dedicated computer room, saving the construction cost of the computer room;
2. Integrated implementation of modular matching units
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. Programmable PLC control, 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 automatically operates according to the refrigeration load, and each system component (host, water pump, water tower) automatically links, communicates, controls, and coordinates operation;
4. Industrial grade high-end and high standard design
Adopting high configuration and system integration to cast high-quality products, a professional team designs according to industrial standards, with low noise and minimal vibration. Designed according to industrial standards, it is suitable for 24/7 uninterrupted operation throughout the year.
6. Compact structure, stable performance and operation
Using high-quality imported twin-screw bearings, its moving parts are only 1/10 of those of a piston compressor, and its vibration is only 1/5 of that of a piston compressor. High precision German FAG and Swedish SKF bearings are used in both radial and axial directions, combined with axial thrust balance drums to effectively balance axial loads. The failure rate is only 1/10 of that of piston compressors, and the control components ensure the long-term safe and stable operation of the unit. The condenser and dry evaporator of the integrated water-cooled chiller unit both use high-efficiency heat transfer tubes, and the main engine adopts an imported high-efficiency semi closed twin-screw compressor, which has many advantages such as compact structure, small volume, light weight, and small installation position. The semi enclosed twin-screw compressor has fewer moving parts and uses a 5:6 ultra efficient screw rotor. There is no direct wear between the rotors, making it highly reliable. 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 by 20% -30% compared to reciprocating compressors, and has obtained IS09001 certification and multiple European and American countries;
7. A comprehensive energy control system
The integrated water-cooled chiller unit single compressor has a four stage and stepless capacity control system, with energy regulation of [100, 75, 50, 25 (or start, 0%]). It automatically adjusts the start and stop of the unit according to load changes, making it more energy-efficient. During operation, the computer control system will change the energy output of the unit based on changes in the client's thermal load. The microcomputer quickly determines the signal to push the slide valve to the required energy by monitoring the difference between the actual load measured and the user's setting. In multiple systems, it works in an optimized way that minimizes electrical energy consumption during cooling output. It not only exhibits excellent performance at full load, but also has high operating efficiency even at partial load
8. The refrigeration system operates independently
A large capacity integrated water-cooled chiller unit has two or more independent refrigeration circuits, so even if one circuit fails/needs maintenance, the other circuit can still operate normally. Equipped with backup function, especially suitable for industrial non-stop environments; The imported PLC human-machine interface is a LCD touch screen with graphical display, easy to operate, and available in both Chinese and English. Equipped with RS485 national standard communication interface, it can be connected to DCS system and can be connected to the entire factory automation network for remote control and monitoring. The parameters are displayed in two ways: graphics and text tables, 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.
9. Microcomputer programmable PLC controller with multiple protection functions
It has protection functions such as compressor coil temperature high protection, oil preheating timed power on/off, cold water flow switch, cold water outlet temperature low protection, Y - △ start failure protection, exhaust temperature high protection, compressor overload protection, power-off memory function, frequent start stop protection, voltage abnormality protection, low oil level protection, high and low voltage protection, etc;
10. Multiple protections, safe, reliable, and stable
Provide comprehensive protection from refrigeration system, electrical system to water system to ensure 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 to ensure the operation of the unit; In addition to the internal protection module of the compressor providing functions such as overvoltage, undervoltage, phase loss, and overload protection, the pressure control devices of the refrigeration system can enable the unit to operate;
11. Easy to install and run in a timely manner
The industrial grade dedicated testing platform ensures that all components of the integrated water-cooled chiller unit have been installed, debugged and tested under different operating conditions in the factory, ensuring that each equipment has been shipped and filled with refrigerant and refrigeration oil. Users only need to connect the water 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 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.
