All DC Inverter Technology to Improve Compression Efficiency 

All DC inverter compressor and high-performance high pressure chamber are adopted to reduce loss of overheat and improve compression efficiency from direct intake. Compared with low pressure chamber, the compression efficiency is improved. High-efficient permasyn motor is adopted to provide better performance than traditional DC inverter compressor.

All DC Inverter Compressor

All DC inverter compressor is used in this system. It can directly intake gas to reduce loss of overheat and improve efficiency


High-efficient permasyn motor is adopted to provide better performance than traditional DC inverter compressor.


Technology of Maximum Torque Control with Minimum Current It  can  reduce  energy  loss  caused  by  device winding so as to realize higher efficiency.

Low-frequency Torque Control It can directly control motor torque, through which fan motor can run at a low speed. Users will feel more comfortable while requirements of the system are also met.

180° Sine Wave DC Speed Varying Technology It  can  satisfy  various  places’  demands  for different temperature and is able to save a great deal of electricity and provide users with utmost comfort at the same time.

Sensorless DC Inverter Fan Motor

Stepless speed regulation ranges from 5Hz to 65Hz.Compared with traditional inverter motors, the operation is more energy-saving.


Sensorless control technology guarantees lower noise, less vibration and steadier operation.

88HP Max Capacity-The Largest Free Combination 

Max capacity of single outdoor unit reaches 22HP and max combination capacity is even up to 88HP, in an industry leading level.

Wide Range of Operation Condition

Outdoor operation temperature range is improved to  -5℃~52℃  in  cooling  and  -20℃~24℃  in heating.

Five-way Piping Connection 

Piping and wiring are available to the front and back, left and right, and bottom.

The  five-way piping  connection  reduces installation difficulty and cost, improves the installation efficiency.

No Need Wired Controller for Debugging

When the project is not completed, debugging can be conducted for the system without wired controller to prevent damage to the wired controller during construction process. After the project is finished, install the wired controller, which can prevent unnecessary loss.

Easy Installation and Maintenance

Compact Design
With compact design, the outdoor unit can be carried to the roof of building through elevator, with no need of crane. It is easier for delivery and installation.
Easy Transportation
Optimized base frame Optimized base frame, the locating and fixing of the  outdoor  unit  during  installation  is  more convenient and reliable.

High Efficiency and More Energy Saving 

Thanks to the advanced all DC inverter technology, optimized system design and accurate intelligent control technology, Westinghouse VRF have high EER of up to 4.31 and COP of up to 4.55

New Generation of Energy-saving Operation Control Technology with Energy Saving Up to 20%

The MultiW5 system has 2 modes for energy saving, which can be chosen to meet different electricity demands. Mode 1: In  auto  energy-saving  mode,  the  system  will self-adjust parameters according to the operation status, thus to lower the cost of electricity. Up to 15% of energy can be saved. Mode 2: In compulsory energy-saving mode, the system will limit power output forcibly. Up to 20% of energy can be saved.

Intelligent Defrosting Control 

During the heating process, the frost status of the unit will be different after affecting by factors of outdoor ambient temperature, load status and operation time. Through real-time detection of operation parameters of the system, it can decide the defrosting time by intelligently estimating the thickness of frost, high pressure of system and blockage status of heat exchanger. 

Lower Power Consumption Operation Mode

As for the area with power consumption limited time period, the maximum power consumption can be set for the operation. Basing on the power consumption of unit and user’s requirement, power consumption limitation can be set according to 100%, 90% or 80% of the capacity of complete unit. In this case, user can have more selection at the power consumption limited time period


Engineering Debugging for Convenient Construction

MultiW5 CP has five auto debugging features:

Automatic allocation of IDU and ODU addresses     

Automatic detection of IDU and ODU quantity     

Automatic detection of errors     

Automatic start-up of debugging     

Real-time judgment of pipe errors


Diversified debugging methods for satisfying different requirements and improving debugging efficiency:

Button debugging of outdoor unit

Special WMV debugging system

CE41-24/F(C) debugger has functions of debugging of complete unit, independent debugging of indoor unit, malfunction display, data record and so on. It’s no need to connect special software and PC. Moreover, it can connect external USB storage data.
