Home Reverse Cycle Refrigerated System Multi-Head Split Systems

Multiple areas can be airconditioned using a combination of heads (hi-wall, bulkhead, ducted, floor standing, cassette and under ceiling type) of the same or different types. They are popular for individual independent control with a single outdoor unit.

Multi-head air conditioners are basically 2 different types:

  1. 1. Multi-split system
  2. 2. Variable Refrigerant Flow (VRF/VRV) system

Multi-split systems are composed of (2 – 5  Indoor units and 1 Outdoor unit). With up to 5 indoor units, Multi-Split Systems are ideal for applications desiring individual room comfort in a space-saving design. These systems offer excellent energy efficiency levels for enhanced home comfort and energy savings. These are suitable for new construction, renovation projects and existing dwellings.

MULTI-SPLIT SYSTEMS

The VRF or VRV type multi-head systems are composed of (2 – 9 Indoor units + 1 Outdoor unit). With up to 9 indoor units, these systems are the ultimate, flexible solution for individual zone comfort. Connecting up to nine indoor units to a single outdoor unit reduces installation space and costs while maximizing comfort and energy savings. With a choice of 30+ unit types in a wide range of capacities, this system allows mixed and matched combinations for Absolute Comfort in almost any residential application.

The type of system your home requires will depend upon factors such as the size of the room, its location and your specific needs to name just a few. To see what system is best for you, here is a brief outline of the different systems available and where they might be ideally suited.

VRF/VRV SYSTEMS

Types of heads

Hi-Wall Type

Wall mounted indoor units are the most common in Australian homes. They are mounted on the wall and circulate air to heat or cool a room evenly. They should be located so the airflow can reach as much of the room as possible.

Bulkhead Type

Compact and lightweight, so are easily installed in limited spaces. Highly flexible in installations, can be fitted in bulkheads, false ceilings, above wardrobes / Walk-in-robes and between the drop ceiling and ceiling slab. Also ideal for shallow ceilings.

Ducted Type

For small to large spaces in need of a concealed duct-type indoor unit. These units range from compact design with low airflow to extremely powerful with high static and airflow for large areas.

Floor Standing Type

These are positioned on the floor or above the skirting against a wall. Also, can be semi or fully recessed into joinery. They should not be positioned behind lounge suites or couches that obstruct the airflow, to operate efficiently, they need clear space in front of them. Ideal in areas with low vertical walls.

CassetteType

The ideal indoor unit for installation inside narrow false ceilings with only the decoration panel visible after installation. A simple design makes it comfortable to the eye in the living rooms or bedrooms.

Floor/Under Ceiling Type

These units can be positioned on the wall at floor level or above the skirting board or attached to the underside of the ceiling (although less common). The major benefit of these units is that they are highly practical in homes where wall and floor space is limited.
