BENEFITS

What is a Hybrid?

The blending of a complex VRF system with the simplicity of a multi-zone system to create a new hybrid solution that shares the best of both systems.

Why Flex?

The ability to create the right combinations, the right quantity (up to 8-zones), the right style indoor units, and the right capacity. It’s the right choice for your home or business.

Why Inverter?

An Inverter is a system that controls the rotational speed (not just an ON/OFF signal) of an electric motor by adjusting the frequency and voltage of the electrical power supplied to the motor. The inverter constantly regulates the compressor speed to its optimum energy usage, producing higher refrigerant performance with less power consumption.

TYPICAL INVERTER VRF SYSTEM

• Variable speed compressor

• Computerized zone control

• Expansion valves are mounted either within or near the indoor unit, and engineered piping maximizes compressor efficiency to create an optimized refrigerant path.

AHRI defines VRF as having three main features: (1) a variable speed compressor, (2) a computerized control individual zoning system and (3) optimized refrigerant path of installation.

HFI vs. Multi vs. VRF

TYPICAL INVERTER MULTI-ZONE

• Variable speed compressor

• Computerized zone control

• With the expansion valves mounted in the outdoor unit, it does not have an optimized refrigerant path.

Halcyon Hybrid Flex Inverter

• Variable speed compressor

• Computerized zone control

• Remotes expansion valves from the outdoor unit to mid-stream in the refrigerant piping, creating a semioptimized refrigerant path.

• 2 outdoor units needed

• No separation tube assemblies needed

• All flare

• 2 separation assemblies needed

• All sweat connections

• 7 separation assemblies needed

VRF Limitations

• Expensive

• Sweat connections

• Computer design required

• No efficiency label today

• Increased labor to install

Power

130% Connectable Capacity (AOU48RLXFZ1 Only)

The HFI system is rated at 48,000 BTUs but you can connect up to 130%, or 62,000 BTUs of rated indoor unit capacity to the AOU48RLXFZ1. Connectable capacity allows you to connect indoor units that can exceed outdoor unit capacity. However, if you connect indoor units that exceed 100% of the outdoor unit’s capacity there are limitations.

If all indoor units are cooling or heating at the same time, the system will limit

their capacity so that their total matches the outdoor unit’s capacity. When a zone meets a desired set temperature it requires less capacity. The unused capacity is then distributed to the remaining indoor units, increasing their capacity.

For Example: The load on a small 2-story office building with a business downstairs and worker apartments upstairs is 62,000 BTUs (38,000 BTUs downstairs and 24,000 BTUs upstairs) but the workers aren’t upstairs and downstairs at the same time, therefore not all units will be running simultaneously allowing 100% heating or cooling to occupied spaces.

Compact Size

The compact size of outdoor unit AOU48RLXFZ1 allows for many installation opportunities.

Self Diagnostic Feature

This printed circuit board provides three modes of diagnostics setting, monitoring and function mode, as well as error codes. It also provides a precommissioning check function. Setting mode allows optional functions to be selected. Monitoring mode provides temperature for each thermistor, compressor operation and other functions. Function mode provides cooling test run, heating test run and pump down operation.

Piping Flexibility

Contractors can choose the best direction for piping from the outdoor unit.

DC Twin Rotary Compressor

A high performance, low noise, large capacity DC twin rotary compressor is used. Includes Quiet Mode for night operation.

Long-life

Ion Deodorization Filter

The filter deodorizes by powerfully decomposing absorbed odors using the oxidizing and reducing effects of ions generated by the ultra-fineparticle ceramic.

+ The filter can be used for approximately 3 years if it is washed with water when dirty to restore it's surface action.
