outdoor unit of air conditioner
outdoor unit energy saving
Energy Management System (EMS)
Floating refrigerant temperature to balance comfort and efficiency. The evaporating temperature is automatically adjusted according to both indoor and outdoor temperature to maximize the comfort and energy efficiency. Output limitation during electricity supply restrictions. With the integration of EMS, for projects with temporary electricity supply restrictions, VC Pro VRF can be set to output 40-100% capacity.
outdoor unit parts 4-side heat exchanger
G-type heat exchangers have higher energy efficiency
High efficiency refrigerant flow
The high efficiency refrigerant flow increases the proportion of liquid refrigerant in heat exchanger and improve heat exchange efficiency.
WIDE OPERATION RANGE
Wide Capacity Range
For single unit, the footprint is small and maximum capacity is up to 30HP. For combined units, maximum three 30HP units can be combined with capacity up to 90HP.
Wide Operation Range
The VC Pro VRF can operate stably in a wide ambient temperature range: from -5°C to 55°C in cooling mode.
Long Piping Capability
Total piping length: 1000m
Longest piping length-actual (equivalent): 175m(200m)
Longest piping length after first branch: 40/90*m
Level different between IDUs and ODU-ODU above (below): 90m (110m)
Level different between IDUs: 30m
*The longest length after 1st branch is 40m as standard but can be extended up to 90m under certain conditons.
outdoor unit of air conditioner high reliability
Real-time Refrigerant Amount Monitoring
The temperature and pressure of refrigerant can be real-time monitored by the outdoor unit. When the level of refrigerant is too low or too high, it can cause damage to the unit and poor performance. VC Pro outdoor unit can detect excessive or insufficient amount of refrigerant to ensure consistent performance.
Duty Cycling and outdoor unit protection
Duty cycling equalizes the running time of the outdoor units stand in multi-unit system and of the compressors in each unit, significant extending compressor lifespan.
Backup Operation
In units with two compressors, if one compressor fails, the other compressor can run on its own for up to 4 days, allowing time for maintenance or repair whilst maintaining comfort.
HIGH RELIABILITY
Refrigerant cooling PCB
The VC PRO VRF uses refrigerant cooling technology to cool the electric control box. It decreases the average temperature of electrical control components by about 8 degrees, guaranteeing the stable and safe running of the control system.
Intelligent Configurations
Intelligent configurations greatly simplify installation, commissioning and servicing.
Field local configurations achieves quick and easy on-site
settings, simplifies installation and commissioning.
System checking and settings also can be easily achieved via
wired making the configuration more flexible and convenient
A desktop or laptop PC can be used for browser-based access to achieve system configuration through IMMPRO gateway via LAN connection.
Precise Oil Control Technology
Four stages of oil control technology ensure all outdoor compressor oil is always kept at a safe level, eliminating any compressor oil shortage problems.
Compressor internal oil separation.
High-efficiency centrifugal oil separator (with separation efficiency of up to 99%) ensures that oil is separated from the discharge gas and returned to the compressors in a timely fashion.
Oil balance pipes between compressors ensure even oil distribution to keep compressors running normally.
Auto oil return program monitors the running time and system status to ensure reliable oil return.
Easy installation and outdoor unit service
Oil Balance pipe not required
With the new oil management system, there is no need of oil balance pipe.
Automatic Refrigerant Charging/Recycling Function*
Automatic refrigerant charging and recycling makes installation and service easier and more efficiency
*This function is available as a customization option.
Dust-clean function*
The innovatively designed dust-clean function enables the outdoor unit to prevent the dust by itself.
This function is available as a customization option.
outdoor unit air conditioner enhanced comfort
Optional silent modes
Several noise reducing components reduce the running noise of outdoor units.
Precise temperature control
VC Pro outdoor unit uses multiple and high precision EXVs to create comfortable indoor environment. The EXV control precision is up to 3000-stage which can precisely control refrigerant flow and guarantee stable indoor temperature. In this way, temperature setting can be adjusted in 0.5°C step, enabling precise comfort control.
