Advantages of
Inverter Technology
nReaches the desired temperature
quickly
nProvides precise temperature
control and continuous
dehumidication (cooling mode)
nExtends component life by
eliminating on-off cycling
nOperates exceptionally quietly
because the DC compressor
runs mostly at low speed, which
also reduces any vibration and
associated noise
nSaves energy by matching the
compressor speed to the demand;
rated at up to 23.5 SEER
nDelivers extra heating capacity
even at low ambient temperatures
‘CRUISE CONTROL’ FOR
YOUR MINI-SPLIT SYSTEM
Iverter Technoog:
All Comfort-Aire mini-splits use inverter
technology to maximize comfort by
reducing temperature uctuations while
saving an estimated 40% or more on
energy consumption, compared with
traditional mini-split systems.
An inverter is an electrical device that varies the frequency of the power going
to the compressor. This allows the compressor to adapt its power output to
precisely match the load requirement.
You might say it’s like the cruise control on a vehicle. The inverter-driven
compressor automatically adjusts its speed to quickly reach and then maintain
the set point. When maximum capacity is not needed, the compressor
speed decreases—and with it, the power needed also decreases, resulting in
improved energy efciency.
Indoors one or more air handlers are equipped with temperature sensing
devices. The inverter reacts to both indoor and outdoor temperature
uctuations, constantly adjusting the compressor speed to match the demand
for cooling or heat. When the outdoor condenser fan runs, its speed matches
the need for heat rejection.
Highly accurate sensors also allow one compressor to meet the demands of
multiple indoor zones. The inverter-driven compressor will operate at the
speed necessary to maintain the set temperatures of up to ve zones.
Once the set point is reached, the system “cruises along,” keeping the
temperature constant, but responding if the demand changes.
Compare this to a conventional mini-split which cools or heats by running the
compressor until the setpoint is reached and then turns off, turning on again
when the temperature falls below the setting. This on-off cycling results in
temperature uctuations that affect comfort, and also adds to wear and tear of
the components, similar to the effects of driving in stop-and-go trafc.
Temperature isn’t the only contributor to comfort: humidity is critical.
Dehumidication, especially during hot, muggy weather, is an integral
component of cooling. When the compressor in a conventional system cycles
off, dehumidication also stops. With an inverter system, excess moisture in
the air is removed all the time because the unit runs constantly, even when it’s
running at low frequency—or “economy” speed.
