Soft-start technology provides the smoothest PTAC sound available
The variable-speed operation of the FreshAire PTAC allows the unit to work at the optimal speed to match the
true load of the room. This not only provides the best energy consumption curve it also adds to guest comfort by
eliminating the harsh start-ups associated with single speed compressors.
THE CURVES BELOW ILLUSTRATE THE DIFFERENT SOUND CHARACTERISTICS OF A SINGLE-SPEED PTAC
VERSUS A FRESHAIRE MODEL PTAC.
TRADITIONAL PTAC FRESHAIRE INVERTER PTAC
At initial start up, a fixed
capacity system slowly reaches
the set temperature.
FASTER TO SETPOINT
At initial start up, utilizes variable
capacity to quickly reach the set
temperature.
Complete shutdown once set
temperature is achieved.
MAXIMUM ENERGY SAVINGS
Reduces capacity as set tempera-
ture is achieved.
Temperature within the space
rises until 2nd system start up.
MAINTAINS PRECISE COMFORT
Variable capacity maintains set
temperature keeping space
comfortable with reduced energy
consumption.
Variable capacity operation pro-
vides improved humidity control
in the guestroom.
System works at full capacity to
again reach the set temperature.
System cycles on and off
continually to maintain the set
temperature.
FreshAire units with inverter
compressors deliver
equivalent SEERs up to 15.0;
application HSPFs up to 11.57,
and offer many advantages
over traditional PTACs.
• Improved dehumidification
• Quieter start-up and operation
• Better efficiency during part load
hours of cooling & heating
• Reduced temperature swings
