Unlike traditional HVAC systems, central ducted heat pumps distribute conditioned air through a complete duct network, providing balanced airflow, stable indoor temperatures, improved humidity control, and enhanced comfort throughout the building.

The system supports integration with residential air handlers, electric heater kits, fresh air ventilation systems, smart thermostats, and zoning controls, making it an ideal solution for energy-efficient modern buildings.

YUJU EnvironTech provides OEM manufacturing, project supply, and customized HVAC solutions for global distributors, contractors, and developers.

Key Features

Next-Generation R454B Refrigerant Technology

The system utilizes low-GWP R454B refrigerant, providing a more environmentally responsible alternative to traditional R410A systems while maintaining excellent heating and cooling performance.

R454B technology supports the global HVAC refrigerant transition and helps future-proof residential and light commercial HVAC installations.

High Energy Efficiency Performance

Advanced inverter compressor technology and optimized refrigeration components deliver stable operation, lower energy consumption, and improved seasonal efficiency.

With high SEER2 performance, the system helps reduce operating costs while maintaining comfortable indoor conditions throughout the year.

Whole-Home Comfort Distribution

Through central duct distribution, conditioned air reaches every room evenly, reducing temperature differences and improving overall indoor comfort.

The system is ideal for whole-house HVAC applications requiring reliable temperature control and balanced airflow.

Quiet Operation

Low-noise inverter compressors, optimized fan motors, and advanced airflow design provide quiet operation suitable for bedrooms, living spaces, offices, and hospitality applications.

Flexible Installation Options

The indoor air handler supports multiple installation configurations including upflow, downflow, and horizontal airflow arrangements.

This flexible design allows contractors to adapt the system to different building layouts and installation requirements.

Smart Control Compatibility

Compatible with programmable thermostats, Wi-Fi smart thermostats, HVAC zoning systems, and fresh air ventilation equipment for intelligent comfort management.

Advanced Whole-House HVAC Solution

A central ducted heat pump system provides complete climate control through a centralized outdoor heat pump unit, indoor air handler, and duct distribution network.

Compared with multiple independent air conditioning units, a ducted heat pump solution delivers more balanced airflow, cleaner appearance, quieter operation, and better whole-building comfort.

The system can be integrated with:

• Residential Air Handler Units
• Smart Thermostats
• Motorized Zoning Dampers
• Fresh Air Ventilation Systems
• Humidity Control Equipment
• Indoor Air Quality Modules

System Components

Outdoor Heat Pump Unit
