Also in case of power outages, Haier offers customized products to realize automatic restart once the power recovers to ensure quick recovery of cooling.
Professional
Haier magnetic bearing centrifugal chiller owns professional design, manufacturing, testing and after-sales service, providing the high reliability of whole process.
Design
The chiller adopts compressor, EXV, controller and other key components of famous brands. All kinds of sensors, valves, electrical parts must be carried out more than 100 tests to ensure the reliability of the use of components. Industrial-grade PLC control achieves wider working temperature range and higher protection level. Magnetic bearing centrifugal compressor eliminates the need for the gear system and oil lubrication system, which means simpler structures and lower possibility of failure. In addition, Haier unique system design and control logic brings higher efficiency and reliability for the chiller.
Manufacture
Haier smart interconnected factory provides the automatic intelligent manufacturing, which improves the production efficiency and quality reatly.
Automaticly expanding tube. ABB robot detects the position of copper tubes through visual recognition system and feeds back the parameters of expanding tube to realize expanding tube automaticly. The positioning tolerance is only ±0.25mm, ensuring no defect and no missing expanding.
Automatic cutting and welding. The robot finds the position for cutting and welding through the intelligent positioning system, which realizes full automation and greatly improves the efficiency. Cutting tolerance is less than 1mm to ensure high quality.
Automatic leak detection. ABB walking robot detects the position of copper tubes through visual recognition system, automatically finds the position and detects leakage, automatically checks system drawings, and automatically marks, so as to realize automatic leak detection.
Convenient
Testing
All models are qualified for AHRI certificate, so the products capacity and energy efficiency are guaranteed. Moreover, all the units will be tested comprehensively at factory before the unit ships to the jobsite. And an optional witness test in our testing facility can be scheduled. In addition, Haier's test facility is capable of evaluating the performance of the unit based on customer defied parameters. Haier's laboratories are certified to provide professional evaluation of your products.
Convenient
Operating
Haier magnetic bearing centrifugal chillers are used in thousands of projects, including hotels, offices, hospitals, factories, shopping mall, universities, data centers, etc. Excellent application experience helps Haier continuously improve the design and optimize the product, which brings the chiller high stability and reliability.
Cloud service
Through the built-in internet cloud service protocol module, the chiller operating data can be collected to the cloud service center via 4G and Ethernet, thereby achieving remote monitoring, fault alarm, energy consumption analysis and historical error.
In addition, all the above function can be used via the smart APP. It's more convenient.
Fault alarm
During the operation time, real-time prediction can be made according to the operation condition of the unit, and early alarm will be given for possible faults.
Energy consumption analysis
The cloud service interface displays the accumulated electric consumption, accumulated cooling capacity, average COP, etc. of the last 7 days. Users can also query the energy consumption data or graphic data trend in any period according to their needs, and download the energy consumption analysis report.
Historical error
When the unit occurs error, installers can check the error records, including the fault time and reason, and quickly give response.
Remote monitoring
Haier intelligence cloud service realizes remote monitoring of unit operation data on real time, including water temperature, instantaneous load and power input, energy efficiency and so on.
Building automation system
The Modbus and BACnet communication modules are provided for the seamless connection with building automation system.
R1234ze(E)
Environmental impact
Solstice ze has a GWP of <1, exceeding existing climate protection goals. • Helps with eco-design directives • Reduces direct CO 2 emissions by 99.6 percent • Reduces indirect CO 2 emissions due to the lower energy consumption
Safety
Solstice ze Refrigerant is significantly safer in use than alternatives such as hydrocarbons and ammonia, which are either extremely flammable or highly toxic.
Oil free system
Conventional compressors and chillers consume more energy due to the presence of lubricating oil that hinders heat transfer. Even a chiller with an oil content of 4% may lose 9% efficiency. Friction-free magnetic bearings eliminate the cost of those inefficiencies as well as the maintenance costs associated with oil service.
Energy saving
Haier w ater-cooled m agnetic bearing centrifugal chiller can achieve up to 11.5 IPLV at AHRI conditions. Comparing with conventional chiller, it can save 30%~50% o f energy to reduce the operating cost.
Smart control
Except the magnetic bearing technology, Haier patented control technology helps enhance the energy efficiency greatly. It provides the best operating solution for the chiller. When the unit has multiple compressors, the load will be distributed to each compressor reasonably to ensure the optimal operating state of the compressors.
Low sound level and vibration
Because of the completely levitated moving parts assembled by motor rotor shaft and impeller, there is no metal-to-metal contact between moving parts. Very low sound and almost vibration-free level of the chiller are achieved. Consequently, floor mounted spring isolators are not usually required. And the chiller's operation noise is as low as 75dB(A) at 1 meter, while the conventional chiller is higher than 85dB(A).
Condenser rubber ball cleaning system
Haier provides optional condenser rubber ball cleaning device for customers to solve the condenser fouling and scaling problems. The cleaning system runs fully automatically. The cleaning balls are introduced and removed from the system through the ball collector.
The frequency and times of the ball service are adjusted according to the chiller operating condition, and the ball is powered by water pressure to clean the tube.
The use of condenser rubber ball cleaning device can maintain the cleanness of the condenser tubes, optimize heat exchange efficiency and eliminate the requirement of manual cleaning in shut down times. Thus the operating and maintenance costs will be greatly reduced.
User-friendly operation
The chiller is equipped with a 10 inch high-resolution touch screen, which provides an user-friendly operator interface with key operating parameters on the screen. This controller sets three access levels of account for users, maintenance and plant operators to ensure safe using.
Alarm history records
Haier control system has fault analysis function. Users can easily access chiller alarm history via intuitive touch-screen buttons for troubleshooting. Through the alarm records maintenance personnel will find fault date, action taken and the cause of the alarm.
