YORK Millennium

OVERVIEW

Introducing the YORK Millennium 25, 30, & 40 ton rooftop line - units designed to provide peak performance and value both today and for years to come. When we aske d our customers what they wanted in a new rooftop line, we were careful to listen to both the needs of today and tomorrow. So, you'll find that Millennium units not only help you solve today's problems, but can handle tomorrow's difficulties as well:

Industry Leading Efficiency EER 25 ton) rating makes it the most frugal energy consumer in its class. When it comes to lower operating costs, Millennium simply outperforms the competition.

Double Wall Construction walled as standard. The galvanized sheet metal liner provides the best protection against microbial growth, helping both the unit and the indoor air stay fresh and clean. And, the rigid sheet metal inner liner keeps the insulation completely out of the air stream, eliminating concerns about fiberglass particles.

Drain Pan Whisks Away Condensate quently the source of microbial contamination. Competitive drain pans often are insufficiently sloped to properly drain all of the condensate, causing drain pan corrosion and bacterial growth to begin almost immediately. The YORK design is sloped at the 1/4” per foot recommended by the ASHRAE

62.1-2004 ventilation draft standard, with an extra large drain connection capable of removing up to three gallons of condensate per minute. It is available in either powder coat painted steel or stainless steel for long life.

Efficient, Durable Scroll Compressors design uses industrial grade hermetic scroll compressors for peak efficiency and low noise operation. The compressor design is so durable that it can actually hold more liquid charge without slugging than is present in each refrigerant circuit at shipment, dramatically reducing the chances of ever slugging a compressor with liquid charge.

Multiple Refrigeration Circuits for Greater Turndown YORK Millennium unit has intertwined 10 ton circuits (12.5 ton circuits on the 25 ton) - giving the best unloading capability in the industry. With more and more designs requiring higher outside air quantities, the lower capacity capability is an outstanding way to neutralize outside air without over-conditioning the space on off-peak days. And, Millennium's high quality balance-port thermal expansion valves are more effective at metering refrigerant flow in part-load conditions, making Millennium a peak-performer across a wide capacity range.

FEATURES AND BENEFITS

When it comes to flexibility, Millennium really shines. Our customers were clear about one thing - not all installations are the same. Some have very simple needs, others are more involved. The YORK Millennium serves both markets - and all of those in between - extremely well. YORK engineers crafted a design which is both uniquely flexible and competitive, giving you the best of both worlds. In addition to a competitive base product, Millennium offers unparalleled flexibility. Optional features include:

Variable Air Volume volume by inlet guide vanes or variable frequency drive - the choice is yours. All Millennium VAV units come standard with hot gas bypass to give extended operation range.

- YORK gives you the ability to vary air

Optional Head Pressure Control - For those applications where mechanical cooling is required below 40°F, optional low ambient operation allows compressor operation down to 0°F.

Easily Upgrade Motor Efficiency to Meet Tighter Codes Optional high efficiency motors help you make simple upgrades to meet more demanding building and energy codes.

Enhanced Filtration Options

- Millennium gives designers the flexibility to meet various IAQ requirements with a full range of rigid and throwaway filters at different efficiency levels.

Vibration Isolation

- The Millennium's neoprene mounts are typically sufficient for most applications but when sound and vibration transmission are a major concern, YORK offers 1" and 2" isolation springs for even greater protection from supply air fan noise and vibration.

Corrosion Resistant Coils

- Many industrial and seacoast applications require enhanced protection from corrosive environments.

Optional TechniCoated Coated Condenser and Evaporator Coils - Many industrial and seacoast applications require enhanced protection from corrosive environments. The special dipped phenolic coating process provides a high level of protection for the exposed condenser coil.

Optional Copper-Copper Condenser and Evaporator Coils - For corrosion resistance.

High Capacity Evaporator Coils

- For those applications which require slightly more capacity than offered by the standard Millennium product, YORK offers the option of higher capacity evaporator coils, boosting cooling output without increasing unit size. (30 & 40 Ton R-22 only)

ers. Comparative enthalpy, single enthalpy and dry bulb control are available.

Optional Factory Installed Disconnect

- A conveniently

located actuator handle in the front of the unit can disconnect

line power to the entire unit, eliminating the need for a field provided disconnect. The handle may also be locked in either position through the use of a standard padlock. Millennium's single point power connection makes this option particularly appealing. If desired, the disconnect may be ordered with a 115 volt, GFCI protected convenience outlet, including a factory wired transformer to power the outlet from the single point power connection; the convenience outlet remains operational when the disconnect is open.

Heating Done Your Way

- Millennium offers the choice of natural gas standard or modulating gas heat, electric resistance heat, hot water heat, steam, or no heat at all. Very simply, the choice is yours.

INSTALLATION FEATURES

With YORK Millennium, high performance doesn't mean high complexity. YORK listened carefully to make sure that Millennium was as simple as possible, and service convenience comes standard with each unit. From a single curb size to the easy service access, you'll find that Millennium was designed to be easy from start to finish.

Full Range of Air Flows and Static Pressures nium design gives a complete offering of supply air flows and static pressure combinations to meet most every application requirement.

Single Power Point Connection - Millennium units have a single gas and electric connection, minimizing time at the job site. For further installation flexibility, power and gas connections may be brought up from the curb or through the side of the unit.

CONSTRUCTION FEATURES

YORK's Millennium rooftop line is built for the long haul, with high end features and construction offered at a competitive price. Millennium units are manufactured at an ISO 9001 registered facility, and each rooftop is completely computer-run tested prior to shipment. Some of the valuable construction features of the Millennium which are not found on competitive units include:

Double Wall Construction and an interior wall, which make for a more rigid design with panels and doors that are solid, not flimsy. The unit features a fully framed construction for even greater stability.

Powder Paint keeps the unit in great condition for years to come.

- Industry leading 1000 salt spray hour paint

- Each unit has both an exterior

HINGED, LATCHED ACCESS DOORS

Low Profile curb, minimizing potential aesthetic conflicts.

Extended flue connection mounted external flue. The flue lifts all products of furnace combustion far above the unit - eliminating the possibility of corrosion in the furnace heat exchanger from recirculating flue gases.

Protective Covering cover the distributor tubing keep distributor tubes from contacting each other and wearing out.

Built-in Hail Guard from the vertical are inherently protected from damage due to shipment, hail, etc.

GIVEN: Required Cooling Capacity 460,000 Btuh

Required Sensible Cooling 390,000 Btuh Required Heating (Gas) 320,000 Btuh Entering Air on Evaporator 83° F DB/ 67° F WB Outside Design Temperature 95° F Supply Fan CFM 13,000 CFM External Static Pressure 1.25 IWG Electrical Supply Voltage 460-3-60 Economizer Required 2” Throw Away Filters Constant Volume

SELECT UNIT:

1. Determine nominal tons: 460,000 / 12,000 = 38.33 Tons

Thus, a nominal 40 ton unit is selected.

2. Reference Cooling Capacity Table for a 40 ton unit with standard evaporator coil.

a. Locate the table for a standard evaporator coil with

95° F air on the condenser.

b. Enter table at 13,000 CFM and 67°F WB air on

evaporator c. Trace to 83° F Entering Dry Bulb column. d. Read 493 MBH total capacity and 403 MBH sensi-

ble capacity. The 40 ton unit will meet the cooling requirements. From

the nomenclature, the unit will be a Y34. Choose the appropriate configuration for the next digit. Assuming bottom return and supply, the fourth digit would be an “A,” making the model Y34A.

3. Find Gas Heating Capacity Table. a. Trace down Output column. b. Find output which exceeds 320,000 Btuh require-

ment. The N5 option gives 426 MBH output.

c. Ensure that it is offered in the Y34 unit. Read option

model as N5.

From the basic nomenclature, the model now becomes Y34AN5. Add voltage code of “4” for 460-3-60. Nomenclature becomes Y34AN54.

SELECT FAN SPEED AND HORSEPOWER REQUIREMENTS OF SUPPLY AIR FAN

1. Find Supply Air Performance Tables for the 40 ton unit. a. Check footnotes and make necessary additions or

deductions to static resistance of ductwork:

Ductwork static resistance 1.25 IWG Economizer static resistance addition (interpolate) =.25 IWG + Gas Heat (High) = 0.5 IWG

Total Static Resistance 2.0 IWG b. Enter Fan Performance Table at 13,000 CFM and

2.0 IWG static pressure:

RPM = 690 BHP = 10.7

NOTE: Either a Class I or Class II blower could be used.

c. Enter the Fan Motor Drive Tables. Selecting a 15 hp

motor allows (service factor of 1.5) for a maximum operating BHP greater than the 10.7 BHP requirement.

SIZE OVERCURRENT PROTECTION DEVICE AND DETERMINE CIRCUIT AMPACITY

1. Find electrical tables for the basic 40 ton unit. a. Enter table for 460-3-60 voltage. b. Find 15 hp in the Suppl y Air Fan column. c. Trace to Minimum Circuit Ampacity column - read

104. d. Trace to Max. Fuse/Breaker Size column - read 110. e. Size wire and overprotection device accordingly. f. Check all footnotes.

HOT WATER HEATING

The YORK Millennium Rooftop units (30 - 40 Ton sizes) can be furnished with a YORK hot water coil as the source of heat (Bottom Supply Only). A one or two row coil will be factory installed in the heating section downstream of the supply air fan and just above the supply air opening in the bottom of the unit.

The hot water control valve will not be provided. The installer will need to field supply a water valve. The installer must also connect the hot water piping, and valve wiring at th e job site for the hot water heat section to be operational.

For all hot water coils the enteri ng water temperature should not exceed 200°F.

STEAM HEATING

The YORK Millennium units (25, 30, and 40 ton sizes) can be manufactured with a steam heat coil (Bottom Supply only). YORK's one row steam coil is installed in the heating section just downstream of the supply air fan and just above the supply air opening in the bottom of the unit.

The steam control valve will not be provided. The installer will need to field supply a steam control valve. Connect the steam piping and valve power wiring at the job site for th e steam heat section to be operational.

There are no provisions in the coil or control sequence to prevent freezing of condensate. The control val ve, piping and field installed wiring connections are particularly vulnerable because they are installed in the vestibule outside of the conditioned air stream.

All piping, control valves, and wiring that is field installed must conform to all local and national codes

Condensate can freeze on the control valve and piping if they are not properly insulated.

SUPPLY AIR DRIVE ADJUSTMENT

At unit start-up, the measured CFM may be higher or lower than the specified CFM shown in Figures 22, 23, and 24. To achieve the specified CFM, the speed of the drive may have to be decreased or increased by changing the pitch diameter (PD) of the motor sheave as outlined below:

Failure to properly adjust the total system air quantity can result in extensive blower damage.

Before making any blower speed changes review the installation for any installation errors, leaks or undesirable systems effects that can result in loss of air flow.

Even small changes in blower speed can result in substantial changes in static pressure and bhp. Bhp or amp draw of the blower motor will increase (see table) by the cube ratio of the blower speed. Static pressure will increase by the square ratio of the blower speed. Tables 26, 27 and 28 are for reference only. All blower speed changes must be made by qualified personnel with strict adherence to the fan laws.

Example: A 30-ton unit was selected to deliver 12,000 CFM with a 20

HP motor and a 856 RPM drive, but the unit is only delivering 11,000 CFM per Figure 23.

Use the equation to determine the required PD for the new motor sheave (12,000 CFM / 11,000 CFM) x 6.7” = 7.31”.

Use the 30-ton table to select a Browning 2B5V74 which will increase the speed of the unit's drive and its supply air CFM 109%.

New drive speed = 1.091 x 856 = 933 RPM New supply air = 1.091 x 11,000 = 12,000 CFM Re-use the existing belts and blower sheave. New motor BHP = (speed increase)3 x estimated motor

BHP at original start-up with 11,000 CFM and 856 RPM = (1.091)3 x 11.0 BHP = 1.2986 x 11.0 BHP = 14.3 BHP New motor amps = (speed increase)3 x measured motor amps at original start-up with 11,000 CFM and 856 RPM.
