Ducted split systems are a popular choice for commercial and residential climate control, combining the efficiency of split-system technology with the flexibility of ducted air distribution. These systems are ideal for delivering conditioned air discreetly through ductwork to multiple rooms or zones.
This article explores the components, types, advantages, and applications of ducted split systems, with an emphasis on how Clivet incorporates this technology into its HVAC product line.
What is a Ducted Split System?
A ducted split system consists of two main parts:
-
Outdoor unit: Houses the compressor, condenser, and expansion valve.
-
Indoor unit: Contains the evaporator coil and blower fan, connected to ductwork for air distribution.
The outdoor and indoor units are connected via refrigerant piping and electrical wiring, while conditioned air is circulated through ducts installed inside walls, ceilings, or floors.
Key Components
-
Compressor (in outdoor unit): Compresses refrigerant, enabling heat exchange.
-
Evaporator coil (in indoor unit): Absorbs heat from indoor air.
-
Ductwork: Delivers air to different rooms or zones.
-
Air handler/blower: Pushes air through ducts.
-
Thermostat/control system: Manages temperature and operation.
Types of Ducted Split Systems
1. Single-Zone Ducted Split System
-
Designed to condition a single area or zone.
-
One thermostat controls the temperature.
-
Simpler ductwork, suitable for small to medium spaces.
2. Multi-Zone Ducted Split System
-
Provides independent temperature control for multiple zones.
-
Each zone has its own thermostat and dampers in the ductwork.
-
Energy-efficient for variable occupancy and usage patterns.
3. Variable Refrigerant Flow (VRF) Systems
-
Advanced multi-zone ducted split systems.
-
Use inverter-driven compressors to vary refrigerant flow based on demand.
-
Can simultaneously heat and cool different zones.
-
Clivet’s ELFOEnergy VRF systems are examples of this category, offering high energy efficiency and flexibility.
