York R-407C Manuale Utente

YORK INTERNATIONAL

• First packaged RTU with 407C optimized design

• Cooling and Heating – Superior operating perfor-

mance provides lower operating costs. Smaller
steps of cooling capacity provide tighter control of
building environment and occupant comfort while
optimizing energy efficiency.

• Indoor Air Quality (IAQ) – Outside air economiz-

ers provide energy savings in free cooling mode,
and can provide a healthier and more comfortable
building environment by introducing fresh outside air
into the building as needed. Indoor Air Quality (IAQ)
requirements for building ventilation and comfort are
controlled through the microprocessor control panel.
Optional air flow measurement provides an accu-
rate means of tracking air quality and alerting the
occupants or building owner to unhealthy situations.

• High-Efficiency Motors – High-efficiency motors are

available for optimum energy efficiency. All motors
used on the eco

2

 packaged rooftop air conditioner

meet U.S. EPACT 1992 minimum requirements.

• Double-sloped stainless steel drain pan – This

double-sloped inclined stainless steel drain pan fa-
cilitates removal of evaporator condensate. Sloped

in two directions conforming to ASHRAE 62n, this
drain pan swiftly minimizes any condensate within
the unit. Best of all, the drain pan is accessible for
periodic cleaning required by IAQ standards.

• Smart ventilation – YORK maintains the leader-

ship role in IAQ products with adaptive ventilation
control. The OptiLogic

TM

 controls provide continu-

ous monitoring of air quality and take action by open-
ing the outside air dampers, bringing in the right
amount of fresh air before air impurities reach un-
comfortable or even dangerous levels.

• Air flow measurement – Precise measurement

of ventilation air flow is possible using an air flow
measurement station which can be installed in the
economizer section.  Proper ventilation air flow is
required to ensure sufficient fresh air is in the build-
ing. A myriad of air flow measurement options are
available from minimum air flow to high-accuracy
full air flow capabilities.  The complete system is
designed as an integrated component of the
OptiLogic

TM

 control system to ensure optimum sys-

tem performance.

• Double-wall construction – Rigid double-wall

construction throughout provides ease of clean-
ing and protects against insulation fiber entrain-
ment in the breathable air. Double-wall construc-
tion also helps improve the acoustical character-
istics of the air handling unit.
