Duct Type

A VRF duct-type indoor unit is a concealed HVAC unit installed in ceilings or walls that uses ductwork to distribute conditioned air, offering quiet operation, flexible zoning, and compatibility with Variable Refrigerant Flow (VRF) systems for precise, energy-efficient heating/cooling in multiple zones using a single outdoor unit, with models varying in static pressure (low, medium, high) to suit different duct lengths and air distribution needs.

Key Characteristics & Types:

1. Concealed Installation: Hidden above ceilings or in walls, only grilles/diffusers are visible.
2. Ductwork: Connects to duct networks for air distribution, ideal for large spaces or integrating with existing systems.
3. Static Pressure Options:
4. Low Static: For short duct runs, smaller spaces, quiet operation.
5. Medium Static: Balances performance and noise for general applications.
6. High Static: For long duct runs and large areas, requiring powerful airflow.
7. Zoning: Works with VRF systems to allow independent temperature control in different rooms or zones.

Benefits:

1. Aesthetics: Minimizes visible equipment, creating cleaner interior designs.
2. Energy Efficiency: VRF technology optimizes refrigerant flow, reducing energy use.
3. Flexibility: Can serve multiple rooms from one unit with zoned control.
4. Comfort: Delivers consistent, balanced airflow.

Common Applications:

1. Hotels, offices, restaurants, large apartments, and commercial buildings.
