Nortek Global HVAC introduces a new 16 SEER, 12 EER,
8.2 HSPF ultra-high energy-efficient unit to its
packaged heat pump line. Model Q7RF is a two-stage
heat pump with all-aluminum Micro-Channel evaporator
and condenser coils for lighter weight, smaller
size, better durability and greater reliability in
Q7RF single-packaged heat pump system features a
small footprint for ease of installation.
Micro-Channel coils contribute to the smaller size
of the unit, offer better heat transfer for higher
efficiency and use up to 30 percent less refrigerant
than systems with traditional coils.
Each unit features Nortek Global HVAC’s patented
defrost process. Traditional tube-in-fin heat pumps
have coil headers on the sides and defrost
horizontally. But in a Micro-Channel heat pump, the
coil is rotated 90 degrees so that the headers are
on the top and bottom, not the sides. If the defrost
started from the top down, the bottom of the coil
would never defrost completely. The Nortek Global
HVAC patented process adds a hot gas bypass so that
hot gas goes from the top-down as well as the
bottom-up, ensuring the entire coil gets defrosted.
Model Q7RF is available in the Broan®, Frigidaire®,
NuTone®, and Westinghouse® brands of HVAC equipment.
Similar model PPH3RF is available in the Maytag®
brand. They are ENERGY STAR compliant and available
in 2, 3, 4 and 5 ton capacities.
