Scroll Compressors –
Reliable, efficient,
trouble-free operation is the true measure of a
packaged rooftop’s value. That’s why YORK
eco
2
Packaged Rooftop Air Conditioners use
established scroll-compressor technology to
deliver dependable, eco nom i cal performance
in a wide range of ap pli ca tions. With the eco
2
Packaged Rooftop, you get the latest generation
of compressor en hance ments added to the scroll’s
inherent strengths. The sim plic i ty of a hermetic
scroll compressor allows the use of fewer moving
parts to minimize breakdown.
•
Multiple Compressor Staging –
Through the
use of the scroll compressor, the eco
2
has the abil-
ity to stage it’s cooling by enabling and disabling
mul ti ple single stage compressors on multiple
circuits. These compressors are manifolded to-
gether in two independent circuits.
•
Compressor Circuiting –
The eco
2
is designed
so that only 2 scroll compressors are in tandem
within one refrigeration circuit. This means more
reliable com pres sors, and less equipment down
time. With multiple circuits, if a compressor
should ever fail on one circuit, the other circuit/s
will re main op er a tion al to work to maintain oc-
cupied loads. The eco
2
sys tem has 2 circuits in
the unit.
ECOLOGICAL AND ECONOMICAL DESIGN
•
High Effi ciency eco
2
rooftop units are optimized
for HFC-410A refrigerant. YORK provides the
FIRST standard product offering that meets the
latest ASHRAE 90.1 energy effi ciency require-
ments.
•
Cooling and Heating –
Superior op er at ing per-
for mance provides lower operating costs. Smaller
steps of cool ing capacity pro vide tighter con trol
of build ing environment and oc cu pant comfort
while optimizing energy effi ciency.
•
Indoor Air Quality (IAQ) –
Outside air econ-
o miz ers pro vide en er gy sav ings in free cooling
mode, and can pro vide a health i er and more
comfortable build ing en vi ron ment by in tro duc ing
fresh outside air into the build ing as needed. In-
door Air Quality (IAQ) re quire ments for building
ventilation and com fort are con trolled through
the microprocessor con trol pan el.
•
Premium-Effi ciency Motors –
Premium-effi -
ciency motors are available for optimum energy
effi ciency. All mo tors used on the eco
2
pack aged
roof top air con di tion er meet U.S. EPACT 1992
min i mum re quire ments.
High-effi ciency motors are standard. Motors are
available in ODP or TEFC construction.
