High-Efficiency, Wide-Capacity VRF Systems Designed for Modern Commercial Buildings

Overview

The DC Inverter VRF System from OUTES delivers a flexible, energy-efficient and scalable climate control solution for commercial, industrial and institutional buildings.
With a capacity range covering 8–112 kW, the series supports both small-to-medium zones and large, multi-storey projects. Advanced inverter technology, long piping design, intelligent control and stable operation under extreme conditions make this system ideal for long-term, intensive operational environments.

Flexible Capacity Range for Diverse Project Requirements

The system portfolio spans:

• 8–33.5 kW: suited for small commercial spaces, retail units, office zones, and modular project deployment

• 25.5–112 kW: engineered for hotels, hospitals, business complexes, manufacturing facilities and mixed-use commercial buildings

The modular configuration allows outdoor units to be combined to achieve higher capacities, ensuring seamless integration into both new installations and retrofit projects.

High Energy Efficiency Through Full DC Inverter Technology

OUTES applies all-DC inverter control across compressors, fans and electronic expansion valves, enabling the system to regulate performance precisely in response to real-time load changes.
Benefits include:

• Reduced energy consumption during partial load operation

• Faster temperature stabilization

• Lower noise output during continuous operation

• Improved seasonal efficiency and reduced long-term operating cost

Stable Operation in Harsh Environmental Conditions

Built for demanding climates, the system maintains reliable heating and cooling performance across a wide ambient temperature range:

• Cooling: up to ~48°C

• Heating: down to ~–20°C (depending on configuration)

This ensures stable performance for year-round operation, even in extreme weather regions.

Long Piping Design for Complex Building Layouts

OUTES VRF systems support large building applications through:

• Extended total piping length

• High elevation difference between indoor and outdoor units

• Flexible connection architecture supporting multiple branches and long horizontal runs

These features are especially beneficial for hotels, offices, education facilities, factories and multi-block complexes where installation conditions vary.

Precision Refrigerant Flow Control

The system’s VRF algorithm manages refrigerant distribution according to the real-time load of each indoor unit.
The result is:

• Consistent temperature control across all rooms

• Improved comfort stability

• Reduced unnecessary energy output during light-load periods

The flexibility of connecting various indoor unit types supports diverse architectural and interior design needs.

Intelligent Control & System Integration

OUTES provides multiple control options to support different building management requirements:

• Centralized controllers for unified monitoring

• Individual wired controllers for room-level control

• Cloud and mobile app access for remote management

• BMS integration via Modbus / BACnet for advanced automation

These options enable efficient operation, energy allocation, scheduling and remote diagnostics.

Reliable Engineering & Project-Level Support

The VRF systems are engineered for:

• Long service life under heavy-duty operation

• High-performance rotary or scroll inverter compressors

• Optimized heat exchangers

• Anti-corrosion treatment for coastal or industrial environments

• Ease of maintenance and quick access design

OUTES also provides application consultation, selection support, and project-based configuration to ensure accurate matching between system capacity and building load demand.

Applications

The system is suited for a wide range of commercial and industrial scenarios:

• Hotels & resorts

• Office buildings & commercial complexes

• Manufacturing facilities

• Schools, universities and public institutions

• Healthcare and rehabilitation centers

• Restaurants, retail chains and multi-zone buildings
