Johnson Controls, the building efficiency leader, is proud to present the YORK Model YLAA Air-Cooled Scroll Chiller.

FEATURES AND BENEFITS

Installation

The YLAA chiller arrives as a factory-assembled package ready to be installed outdoors, either on the roof or at ground level. The air-cooled condensers eliminate the capital, in-stallation and maintenance costs of a cooling-tower circuit.

The YLAA weighs less and has s smaller footprint than other chillers in its class. In fact, it is 20-35% lighter weight than the market average chiller. When the chiller is roof-mounted in new construction, the cost of the support structure can be reduced. In building retrofits, the YLAA can provide the largest capacity in a given space and existing structure.

Power hook-up could not be any easier with the standard single-point connection. A ter-minal block, disconnect switch or circuit breaker is provided to meet the unique needs of every project and minimize installation time and labor. The factory-installed control trans-former steps down the power voltage to the control voltage.

Chilled-water piping is also simple. The water connections are factory-piped to the out-side of the unit, for ease of access. Factory-cut grooves, or optional flanges, make pip-ing connections simple. Optional factory-installed pump kits eliminate the time, cost, and mechanical-equipment room space necessary to install chilled-water pumps.

Press the start button with confidence – your YLAA has been run-tested at the factory to ensure that you will have a successful start-up.

Reliability

The YLAA chiller is proven and reliable, designed to reduce service calls. The scroll com-pressors have logged hundreds of thousands of operating hours in numerous different applications. The corrosive-resistant condenser heat exchangers have been specifically designed for stationary HVAC applications and have undergone extensive laboratory and field testing to extend chiller life and improve performance. They are also more rigid than standard condenser coils, making them less susceptible to damage during rigging, lifting, and installation of the chiller.

Components are designed to keep the chiller up-and-running. A factory-installed water strainer prevents debris from affecting unit flow and/or heat transfer. The rugged thermal-dispersion flow switch is factory-installed at the optimum location in the piping for su-perior flow sensing, reducing the potential for nuisance trips. Intelligent controls protect the chiller while keeping it online, for maximum uptime. Exterior panels of the chiller are powder-coated with highly durable corrosion-resistant paint.

Introduction

Efficiency

YLAA high-efficiency chillers, with their innovative control algorithms, offer industry-lead-ing energy efficiency. Real-world energy efficiency is measured by IPLV (off-design) per-formance, and YLAA chillers provide some of the best IPLVs in their class.

YLAA also offers an efficiency choice. In addition to the high-efficiency units, YLAA chillers are available in standard efficiency models with smaller footprints and lower capital costs.

Only pay for the chiller you need – the multi-efficiency levels of the YLAA allow you to decide the best investment for the job.

Flexibility

The YLAA chiller offers a number of options designed to operate reliably across a wide range of customer needs. It can cool glycol down to 10°F (-12°C). It can provide heat re-covery up to 140°F (60°C), with up to 85% of total heat rejection captured.

When factory-mounted pump kits are considered, there are now more pump sizes to choose from. The optional kits come standard with valves, pressure ports, flow switch, and strainer for quick hook-up, and frost protection to prevent freeze-up. There are also more pump options available: variable-speed drives, dual pumps, service shut-off valves, expansion tanks, and additional test ports for temperature and pressure sensing.

Standard low sound and multiple sound attenuation options allow flexibility in locating the chiller, and reduce the cost for field-constructed barriers.

Sustainability

The YLAA makes you a leader in sustainability through innovation, not added cost. With the combination of R-410A refrigerant, which has no ozone-depletion potential, and state-of-the-art heat exchanger technology that allows refrigerant charge to be reduced by as much as 30%, the YLAA chiller provides the most ecologically friendly equipment. Part-nered with its low-sound properties for noise pollution prevention, this chiller is a true earth-friendly offering.

JOHNSON CONTROLS 7

Communications

The YLAA chiller comes standard with native communication capability for BACnet (MS/ TP), Modbus, and N2, with optional capabilities available for LON. The standard unit ca-pabilities include built-in-scheduling, remote start-stop, remote water temperature reset and up to two steps of demand (load) limiting depending on model. The standard control panel can be directly connected to a Johnson Controls Building Automated System via the standard factory-installed RS232 communication port.

Serviceability

Minimal maintenance is required to keep the unit operating at maximum performance. If service should ever be required, the YLAA chiller has been designed to simplify the work, keeping costs down. The layout of the chiller locates all the major components that can be serviced near the outside edge. The condenser heat exchangers are light enough that no crane is required for replacement and when it’s time to clean them, city tap water, with water pressure typical of a spray from a common garden hose, is all that’s needed.

AHRI CERTIFICATION PROGRAM

YORK YLAA chillers have been tested and certified by Air-Conditioning, Heating and Re-frigeration Institute (AHRI) in accordance with the latest edition of AHRI Standard 550/590 (I-P). Under this Certification Program, chillers are regularly tested in strict compliance with this Standard. This provides an independent, third-party verification of chiller perfor-mance. Refer to the AHRI site at www.ahrinet.org/ for complete Program Scope, Inclu-sions, and Exclusions as some options listed herein fall outside the scope of the AHRI certification program. For verification of certification, go to the AHRI Directory at www.

ahridirectory.org.

Rated in accordance with the latest issuance of AHRI Standard 550/590 and 551/591.

Equipment Overview

The 55 - 230 Ton (195 - 800 kW) YLAA models are shipped complete from the factory ready for installation and use. The unit is pressure-tested, evacuated, and fully charged with a zero Ozone Depletion Potential Refrigerant R-410A and includes an initial oil charge. After assembly, a complete operational test is performed with water flowing through the evapo-rator to assure that the refrigeration circuit operates correctly.

The unit structure is heavy-gauge, galvanized steel. This galvanized steel is coated with baked-on powder paint, which, when subjected to ASTM B117 1000 hour, salt spray test-ing, yields a minimum ASTM 1654 rating of “6”. Units are designed in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safety code for mechanical refrig-eration, ASME and rated in accordance with AHRI Standard 550/590 and 551/591.

COMPRESSORS

The chiller has suction-gas cooled, hermetic scroll compressors. The YLAA compressors in-corporate a compliant scroll design in both the axial and radial direction. All rotating parts are statically and dynamically balanced. A large internal volume and oil reservoir provides greater liquid tolerance. Compressor-crankcase heaters are also included for extra protection against liquid migration.

BRAZED PLATE EVAPORATOR

The compact, high efficiency Brazed Plate Heat Exchanger (BPHE) is constructed with 316L stainless steel corrugated channel plates with a filler material between each plate. It offers excellent heat transfer performance with a compact size and low weight, reducing structural steel requirements on the job site.

LD18426

The heat exchanger is manufactured in a precisely controlled vacuum-brazing process that allows the filler material to form a brazed joint at every contact point between the plates, creating complex channels. The arrangement is similar to older plate and frame technology, but without gaskets and frame parts.

Water inlet and outlet connections are grooved for compatibility with field supplied ANSI/ AWWA C-606 couplings.

A 20 mesh wye-strainer is provided as standard to provide protection at the evaporator inlet, particularly at system start-up when construction debris may be present in the piping system.

The evaporator is equipped with a thermostat-controlled heater. The heater provides freeze protection for the evaporator down to -20°F (-29°C) ambient. The evaporator is covered with 3/4” flexible, closed-cell, foam insulation (K=0.25).

A factory-wired flow switch is standard, installed in a pipe section at the outlet of the evaporator.

CONDENSER

Coils - Condenser coils are made of a single material to avoid galvanic corrosion due to dissimilar metals. Coils and headers are brazed as one piece. Integral sub cooling is included. The design working pressure of the coil is 650 PSIG (45 BarG). Condenser coil is easily washable with clear water up to 100 PSI (7 bar).

Fans – The condenser fans are composed of corrosion resistant aluminum hub and glass-fiber-reinforced polypropylene composite blades molded into a low-noise airfoil section.

They are designed for maximum efficiency and are statically and dynamically balanced for vibration-free operation. They are directly driven by independent motors, and positioned for vertical air discharge. The fan guards are constructed of heavy-gauge, rust-resistant, coated steel. All blades are statically and dynamically balanced for vibration-free opera-tion.

LD18427

JOHNSON CONTROLS 11

Equipment Overview (Cont'd)

Motors – The fans are driven by Totally Enclosed Air-Over, squirrel-cage type, current pro-tected motors. They feature ball bearings that are double-sealed and permanently lubricated.

UNIT CONTROL SYSTEM

The YLAA chiller is designed with an intelligent control system that operates the chiller automatically with maximum reliability, safety and ease of use. The controls are factory tested and with as little user input as a chilled liquid setpoint the chiller will operate to meet the load demand.

The control system includes native BACnet MS/TP, Modbus and N2 communications, with LON protocol served through an optional eLink communications card.

The operating program is stored in non-volatile memory (EPROM), so power failures and battery discharge will not require reprogramming the chiller. Programmed setpoints are retained in lithium battery-backed RTC memory for five years minimum.

Unit alarm contacts are standard. Contacts for remote chilled liquid temperature reset and two steps of demand load limiting are also standard, for projects without BAS or for redundancy.

DISPLAY

Maximum reliability is achieved through intelligent control. Run hours and starts are av-eraged across all compressors automatically, and between both pumps of the optional dual pump hydro-kit. When compressors are cycled off, an anti-recycle timer ensures the motors have time to cool before starting again, for the maximum service life. At unit shutdown, the unit pumps down automatically to prevent liquid refrigerant from entering the compressors at restart, which can cause premature bearing wear and other compres-sor damage.

Liquid temperature sensors provide feedback to the controller, and logic predicts when additional capacity will be required based on how quickly the unit has loaded or unloaded in the past. This prevents unnecessary compressor cycling and helps maintain setpoint accurately.

If there is a problem that prevents the unit operating properly, the controls are designed to allow the unit to operate safely while making as much capacity as possible. For example, if airflow to the condenser coil is diminished due to a dirty coil, the chiller will unload slightly to provide maximum capacity possible while remaining within the unit operating envelope.

If a fault prevents the unit from starting or causes it to shutdown, the chiller will attempt to restart three times. If it cannot start, a manual reset is required to alert the operator about the fault condition. The fault history is stored in the unit controller RTC memory for the last six fault shutdown conditions. An RS-232 port provides capability to print hard copy reports (printer available separately).

All controls are contained in a NEMA 3R cabinet with a hinged outer door and includes a liquid crystal display (LCD) with light emitting diode (LED) backlighting for outdoor view-ing. There are two display lines, each with 20 text characters per line, and a color coded 12-button non-tactile keypad with sections for display, entry and printing.

BUILDING AUTOMATION SYSTEM INTERFACE

In addition to native BACnet, Modbus and N2, the YLAA chiller accepts a 4-20 milliamp or 0-10VDC input to reset of the leaving chilled liquid temperature. The standard unit ca-pabilities include remote start-stop, remote water temperature reset via up to two steps of demand (load) limiting depending on model. The standard control panel can be directly connected to a Johnson Controls Building Automated System via the standard on-board RS232 communication port. (Factory- installed)

For connection with Johnson Controls Connected Services, an optional interface card (SC-EQUIP) is required and may be factory installed for easier field commissioning. Addi-tional hardware (SC-AP access point), field provided, must be installed remotely from the chiller to interface with the Connected Services remote operations center. Contact your local Johnson Controls office to learn more about Connected Service and to schedule installation during chiller commissioning.

NOTE:

Placement on a level surface of free of obstructions (including snow, for winter operation) or air circulation ensures rated performance, reli-able operation, and ease of maintenance. Site restrictions may compromise minimum clearances indicated below, resulting in unpredictable airflow patterns and possible diminished performance. The unit controls will optimize operation without nuisance high-pressure safety cut-outs;

however, the system designer must consider potential performance degradation. Access to the unit control center assumes the unit is no higher than on spring isolators. Recommended minimum clearances: Side to wall – 6'; rear to wall – 6'; control panel to end wall – 4'0'';

top – no obstructions allowed; distance between adjacent units – 10'. No more than one adjacent wall may be higher than the unit.
