A single zone heat pump is a type of ductless system designed to heat and cool a single area.
Understanding Single Zone Systems
Based on the definition provided, single-zone ductless heat pump systems consist of a single outdoor unit that is connected to a single indoor unit. This configuration makes them ideal for conditioning the air in one specific room or area within a building.
Key Components
A single zone system is characterized by its streamlined setup:
- One Outdoor Unit: This component is installed outside the building and houses the compressor and condenser coil.
- One Indoor Unit: This component is installed inside the space to be heated or cooled, containing the evaporator coil and fan.
These two units are connected by a conduit containing refrigerant lines, power cables, and condensate drain line.
Application
Single zone heat pumps are typically used in scenarios where only one room or a specific area needs independent temperature control. This could include:
- Room additions
- Garages or workshops
- Small apartments or studios
- Areas not reached by central HVAC
- Supplementing existing systems in specific rooms
The reference indicates that for homes requiring heating and cooling in multiple zones (or rooms), a single-zone system is not sufficient for the entire home; you would need an additional indoor unit for each additional zone, which describes a multi-zone system.
