The Rinnai DINLR14Z72 / DONSR14Z72 is a high-capacity reverse cycle ducted air conditioning system designed for larger homes, open-plan living areas, and multi-room properties that require strong whole-home heating and cooling. With its powerful inverter technology, flexible zoning compatibility, and single-phase power supply, it is ideal for larger residential applications where year-round comfort is essential. With 14.0kW cooling and approximately 15.5kW heating capacity, this model is suited to larger homes, open-plan areas, and spaces around 65–100m² depending on insulation, ceiling height, and layout. Its inverter compressor automatically adjusts output to maintain more stable indoor temperatures while reducing running costs compared to fixed-speed systems.

Key Features & Benefits

Powerful Whole-Home Performance

The system is designed to provide strong and even airflow across multiple rooms and larger open-plan spaces. Its high-capacity output makes it suitable for homes with several bedrooms, larger living areas, and more demanding ducted layouts.

Single-Phase Power Supply

This model operates on standard 220–240V single-phase power, making it suitable for most residential properties without requiring a 3-phase electrical upgrade. This can simplify installation and reduce electrical upgrade costs.

Energy Efficient Inverter Technology

The inverter compressor adjusts its speed to match room conditions, helping deliver more consistent temperatures and improved energy efficiency. This reduces power consumption and helps lower ongoing running costs compared to older fixed-speed systems.

Flexible Zoning Compatibility

The system can be integrated with optional zone control systems, allowing users to independently manage airflow to different areas of the home. This helps improve comfort while reducing unnecessary energy use in unused rooms.

Strong Airflow Performance

The high static pressure design allows the system to maintain strong airflow through longer duct runs and multiple outlets. This helps provide more even temperature distribution across larger homes.

Quiet Operation

Despite its large capacity, the indoor unit is designed for quieter operation, helping reduce noise in bedrooms, living areas, and other occupied spaces.

Compact Indoor Unit Design

The indoor unit is designed to fit within most residential roof cavities while still delivering strong airflow performance. Its compact footprint can help simplify installation in larger homes with limited ceiling space.

Wi-Fi Compatible

Optional Wi-Fi control is available, allowing users to remotely control temperature, timers, and operating modes from a compatible smartphone app.

R32 Refrigerant

The system uses modern R32 refrigerant, which offers improved efficiency and lower environmental impact compared to older refrigerants such as R410A.

Wide Operating Range

The system is designed to perform in a wide range of outdoor temperatures, making it suitable for Australian climate conditions year-round.

Ideal Applications

• Large homes
• Open-plan living areas
• Multi-room homes
• Offices
• Homes with long duct runs
• Zoned ducted systems
