VRF Air Conditioning Systems
DC Inverter Multi-Zone HVAC Solutions for Commercial & Residential Buildings
Flexible zoning, centralized control and project-specific VRF solutions for hotels, offices, apartments and commercial buildings.
VRF (Variable Refrigerant Flow) is a multi-zone HVAC system designed for buildings that require independent temperature control, flexible system configuration and efficient part-load operation.
Multiple indoor units can operate from one outdoor VRF system while individual rooms or zones maintain independent temperature settings.
YUJU EnvironTech provides VRF equipment selection, system configuration, OEM coordination and project support for international distributors, contractors and engineering projects.
Modular VRF outdoor systems provide flexible capacity and multi-zone climate control for commercial and residential projects.
VRF technology continuously adjusts refrigerant flow according to the demand of connected indoor units, allowing different rooms to operate according to their individual cooling or heating requirements.
YUJU V8 Pro VRF Series
The V8 Pro series is designed for larger commercial buildings and high-end residential applications requiring modular capacity, long refrigerant piping and reliable operation across changing building loads.
The platform combines full DC inverter technology, EVI compressor technology and intelligent system control to support demanding HVAC applications.
Full DC Inverter Technology
Inverter compressors and fan motors continuously adjust system output according to actual demand, improving part-load operation and reducing unnecessary energy consumption.
EVI Compressor Technology
Enhanced Vapor Injection technology supports heating capacity and compressor operation under low outdoor temperatures, making the system suitable for projects requiring reliable winter heating.
Wide Operating Range
- Heating operation down to -30°C on applicable configurations
- Cooling operation up to 55°C ambient temperature on applicable configurations
- Long refrigerant piping capability
- Suitable for large and multi-floor buildings
- Modular outdoor-unit combinations
YUJU ZTVC VRF Series
The ZTVC series provides another flexible VRF platform for commercial buildings, residential developments and customized HVAC projects.
Its modular architecture allows the system to be configured according to project capacity, building layout and zoning requirements.
ZTVC modular VRF platform for multi-zone commercial and residential HVAC applications.
Variable-Capacity Operation
DC inverter technology allows compressor and fan output to follow actual building demand rather than relying only on fixed-capacity operation.
Flexible Modular Combination
Multiple outdoor modules can be combined for larger-capacity applications, allowing the VRF system to adapt to different project scales.
Long Piping & Installation Flexibility
Extended refrigerant piping and allowable height differences make VRF particularly useful for multi-floor buildings and projects where outdoor and indoor equipment cannot be installed close together.
Remote Monitoring & System Diagnostics
Applicable control platforms support centralized monitoring and operating diagnostics, helping facility teams manage multiple indoor zones and identify system conditions more efficiently.

Multiple Indoor Unit Options
A major advantage of VRF is the ability to connect different indoor-unit types within the same overall system, depending on room layout and architectural requirements.
- Four-way cassette units
- Compact cassette units
- Ceiling concealed ducted units
- High-static ducted units
- Wall-mounted indoor units
- Ceiling / floor units
- Fresh-air processing units where applicable
Typical VRF Applications
| Application | VRF Advantage |
| Hotels | Independent guest-room temperature control with centralized building management. |
| Office Buildings | Different office zones can operate according to occupancy and individual comfort requirements. |
| Apartments | Multiple rooms can use different indoor-unit types while sharing the same outdoor system. |
| Retail & Commercial | Flexible zoning supports areas with different occupancy schedules and internal loads. |
| Luxury Villas | Concealed indoor units, individual room control and centralized management support high-end residential design. |
VRF vs. Conventional Split Systems
| Feature | Conventional Split AC | VRF |
| System Capacity | Typically individual or smaller systems | Variable-capacity multi-zone system |
| Zone Control | Independent per split system | Multiple independently controlled indoor zones |
| Outdoor Equipment | Multiple outdoor units may be required | Multiple indoor units share a modular outdoor system |
| Central Management | Limited | Centralized control available |
| Application | Individual rooms and smaller buildings | Multi-zone residential and commercial buildings |
VRF System Design Requires More Than Equipment Selection
A successful VRF project requires the outdoor units, indoor units, refrigerant piping and controls to be selected as one coordinated system.
Important design considerations include:
- Room-by-room cooling and heating loads
- Total connected indoor-unit capacity
- Outdoor-unit combination
- Indoor-unit type and airflow
- Refrigerant piping length
- Vertical height differences
- Simultaneous operating requirements
- Fresh-air and ventilation requirements
- Electrical supply
- Control and building-management requirements
YUJU VRF Project Support
YUJU EnvironTech works with distributors, HVAC contractors and project customers to coordinate VRF systems according to actual building requirements.
Rather than simply supplying outdoor and indoor units, our project approach considers equipment selection, system combination, application conditions and installation requirements together.
- Cooling and heating load review
- Outdoor-unit capacity selection
- Indoor-unit selection
- System combination planning
- Refrigerant piping coordination
- Control-system selection
- Project equipment schedules
- Technical documentation
- OEM and private-label coordination
- Production and export coordination
OEM & Private-Label VRF Solutions
For distributors and HVAC brands, selected VRF platforms can be coordinated for OEM or private-label applications according to product configuration, project requirements and order quantity.
Customization may include branding, product labeling, packaging, controls, documentation and market-specific electrical configurations where supported by the selected platform.

Frequently Asked Questions
What is a VRF air conditioning system?
VRF stands for Variable Refrigerant Flow. It is a multi-zone HVAC system that varies refrigerant flow according to the operating demand of multiple indoor units connected to an outdoor system.
Is VRF suitable for hotels?
Yes. Hotels are a common VRF application because guest rooms require independent temperature control while building operators benefit from centralized system management.
Can different indoor-unit types be connected to one VRF system?
Yes, subject to the selected VRF platform and system design. Cassette, ducted, wall-mounted and other compatible indoor units can typically be combined within the same system.
Can VRF provide both heating and cooling?
Yes. Available system configurations depend on the selected platform. Heat pump VRF systems provide seasonal cooling or heating, while applicable heat-recovery platforms can support more advanced simultaneous zone requirements.
Does YUJU provide VRF OEM and project support?
Yes. YUJU supports project equipment selection, system coordination and OEM cooperation for distributors, contractors and international HVAC projects.
