YZ CENTRIFUGAL CHILLER

Sight Glass

Variable Speed Drive- Four decades of proven

VSD chillers- VSD is standard on YZ

Low-Pressure Chiller- YORK® has a history of low-

pressure refrigerant chillers to deliver high-efficiency

- YZ is designed to maximize the efficiency of a low GWP refrigerant

- Advanced, single-stage design enables YZ to provide the highest real-world energy efficiency

Optimized Compressor

Magnetic-Bearing Driveline- In 1998, YORK® Navy Systems

pioneered reliable magnetic-bearing technology to cool submarines

- The same durable and efficient technology is used on the YZ

Falling Film Evaporator- Patented design- Reduces refrigerant

charge up to 60%

6

Advanced Aerodynamic System

• Single-Stage Compressor• Exceptional part load performance• Wide operating map• Minimized operating expenses

• Patented VGD Capacity Control• Rapid response to building load changes

• Optimized Suction Line• High efficiency design • Fewer moving parts


7

Induction Motor & Magnetic Bearing Driveline

• Induction motors custom-designed for the compressor speed and torque• High efficiency• Lower complexity VSD technology

• Magnetic bearings• Lubrication free!• Wide speed range• Low maintenance

• Simple, high efficiency, low maintenance driveline!


8

Variable Speed Drive

• VSD is integral to the design of the YZ

• Allows compressor/motor to run at the exact

speed needed based on building load

• Low in-rush current for longer motor life

• Provides highest possible part load efficiency for

real-world energy savings at off-design conditions

• Optional active harmonic filter available


9

Falling Film Evaporator

• Maintains real world operating capabilities

• Minimizes refrigerant charge

• Up to 60% reduction compared to low pressure

flooded designs

• Reduces evaporator diameter

• Up to 20% reduction compared to low pressure

flooded designs

Low pressure refrigerants ‘unlock’ access to higher efficiency & new technology options

Alternate Refrigerant Options for Centrifugal Chillers

We didn’t invest in a next generation platform just to have low GWP.

We did it for the efficiency benefit.


Optimized for Ultimate Performance

Pushing the Efficiency Frontier

When it comes to efficiency, even among our own world-class designs, the YORK® YZ is the new benchmark for part load values.


Evolution of Efficiency


More Efficient More Often

Conventional chillers typically can’t operate below 60° F (16° C)

Entering condenser water temperature as low as 40° F (4.5° C)

Full condenser flow at all load points

Efficiencies as low as 0.090 kW/ton or 39 COP!

The operating map can vary, please contact your local sales representative for project specific details


Real-World Efficiency• Superior off-design efficiency

using:• Variable Geometry Diffuser (VGD)• Variable Speed Drive (VSD)• Magnetic Bearing Technology

• Chillers operate in off-design conditions up to 99% of the time

Up to 41% annual energy savings versus traditional fixed-speed oil-bearing chillersUp to 20% savings versus variable-speed oil-bearing chillers

Up to 41% Savings

Initial Cost

Note: AEC done using 700 ton chiller, in a moderate climate (average building load and run hours)

The New Definition of Sustainability


New Definition of Sustainability

True sustainability means the lowest total emissions – from beginning to end –by designing for the highest possible efficiency.

R-1233zdOptimized

High Efficiency Design

Lowest Total Emissions


The Only Chiller Fully Optimized for True Sustainability

• Total Equivalent Warming Impact (TEWI) = the measurement of a chiller’s direct + indirect emissions• Indirect Emissions - Amount of

energy used by the chiller (based on energy source mix of power generation used to operate the chiller)

• Direct Emissions – determined by impact of possible leak from chiller & GWP of the refrigerant in the chiller (R-1233zd GWP = 1)

• TEWI is a more complete measure of environmental progress

Direct emissions – less than 5% of total greenhouse gas emissions

<

>

Indirect emissions – over 95% of greenhouse gas emissions
