Inverter variable capacity advantages

Inverter technology allows each system to adjust capacity and cooling output to provide only the amount of cooling needed at a given time. For example, an 18000 Btu system will operate even

more efciently at 15500 Btu or less if

that's all that’s needed, reducing energy consumption and improving comfort.

Soft start technology

Friedrich soft start technology starts the

compressor with signicantly reduced

amperage at start up, saving energy versus compressors utilizing locked rotor amperage (LRA).

Zero duct loss

The DOE reports that ducted systems lose an average of 25-40% in performance due to leaks, cracks or disconnections in ductwork.

No ductwork means that ductless systems do not experience duct loss, saving energy and money.

No dirty air ducts*

Now there’s no need to clean dirty air ducts that can harbor dust, germs and allergens that are eventually blown into

your home or ofce.

Zone cooling exibility

Independently condition up to eight (8) separate zones using only a single outdoor unit. Achieve the ultimate in comfort and energy control by cooling or heating only the zones that are in use. And, because each zone is independent of the others, comfort settings can vary.

Optimized airow

The indoor unit's 4-way air swing quickly disperses cool air to all four corners of the room to provide comfort throughout the room within a few minutes. The 'Surge Air' feature moves air at an even higher speed for rapid cooling.

Protects the outdoor coil against deterioration and extends the life of the unit especially in harsh coastal environments.

Heat and cool up to 8 zones utilizing wall-mounted, ceiling cassette and The Insider™ concealed ducted models.

Enjoy the exibility to mix and match systems to t your

application.

Zone cooling and heating provides unmatched customized comfort and energy savings

Occupants have the ability to set the temperature of each zone to their preferred comfort level*, or even turn off units in unoccupied rooms, without affecting other zones.

That’s the beauty and efciency of a

Friedrich multizone system.

*Multizone units cannot heat and cool simultaneously.

The Next Generation of Ductless Split Systems

The Advantages of Friedrich's Precision Inverter System

Single or multizone, Friedrich ductless is superior to conventional systems

Precision Inverter technology varies the compressor, the outdoor and the indoor fan speeds, eliminating constant compressor start-ups/shutdowns that traditional systems require to maintain the set temperature.

Soft start technology starts the compressor

with minimal amperage at start up, saving energy versus compressors utilzing locked rotor amperage (LRA).

This is especially beneficial in multizone systems where room temperature set points vary and some indoor units may be turned off in unoccupied rooms.

Each system can adjust capacity and cooling output to provide only the amount of cooling needed at a given time. The result is optimal comfort with low energy costs.

TRADITIONAL SYSTEM INVERTER SYSTEM

At initial start up, a xed capacity system

slowly reaches the set temperature.

Complete shutdown once set temperature is achieved.

Temperature within the space rises until 2nd system start up.

System works at full capacity to again reach set temperature.

System cycles on and off continually to maintain the set temperature.

At initial start up, utilizes variable capacity to quickly reach the set temperature.

Reduces capacity as set temperature is achieved.

Variable capacity maintains set temperature keeping space comfortable with reduced energy consumption.

The twin-rotary compressor and inverter drive provide superior performance for perfect comfort and optimized energy efciency.

Friedrich J Series ductless utilizes an inverter drive coupled with variable speed, twin rotary compressors for optimal performance and increased energy efficiency.
