4
4 Model YVAA – YORK Variable Speed Air-Cooled Screw Chillers Overview A Chiller As Unique As Your Needs Tailor and tune chiller configuration to specific job requirements Match performance to your design point An industry leader in efficiency and technology
5
5 Model YVAA – YORK Variable Speed Air-Cooled Screw Chillers Overview Key technology elements of the system Heat Exchangers – high efficiency falling-film evaporator & advanced microchannel condenser coil designs Controls – leveraging YORK and Johnson Controls technology & ‘know-how’ Variable Speed Drive – compressor VSD from the industry pioneer, and condenser fan VSD to maximize performance Screw Compressors – proven, industry-leading screw compressor design with more than 15,000 VSD compressors operating worldwide
6
Efficiency Intelligent cost reduction, flexible energy consumption
7
Industry’s lowest energy consumption at design conditions When desired, YVAA chillers can be offered at up to 3.4 EER Industry’s lowest energy consumption at off-design conditions When desired YVAA chillers can be offered up to 4.8 EER Johnson Controls7 Efficiency Intelligent cost reduction, flexible energy consumption Ordinary Chiller YVAA
8
YVAA chiller saves 17% to 30% in annual energy costs For new or replacement installations, the YVAA offers significant savings Johnson Controls8 Efficiency Intelligent cost reduction, flexible energy consumption
9
Easily qualify for rebates based on VSD usage Standard high power factor can earn rebate without added cost Tailor & tune your YVAA chiller to qualify for any Performance Rebate Johnson Controls9 Efficiency Intelligent cost reduction, flexible energy consumption
10
Sustainability Giant step forward, smaller footprint
11
Indirect Emissions Contribute 98% of Chiller GWP Electricity generation is the largest source of greenhouse gas emissions Efficiency of YVAA chiller offers substantial reduction in power consumption & your environmental footprint Johnson Controls11 Sustainability Giant step forward, smaller footprint Direct Emissions Contribute 2% of Chiller GWP HFC-134a refrigerant has ZERO ozone-depletion potential and no phase-out date Falling-film evaporator reduces refrigerant charge by up to 15% Water Consumption Power generation can deplete water resources An indirect benefit of the YVAA chiller: water conservation Gain the efficiency of a water-cooled chiller for the cost of an air-cooled

Low Sound Lower the volume, increase goodwill
14
Off-Design Conditions Occur 99% of the Time Most stringent sound requirements occur on evenings and weekends Standard VSD compressors designed for sound relief a reduced speeds Optional VSD condenser fans will provide further significant off-design sound benefit Further accessories can provide sound reduction at on-design conditions Johnson Controls14 Low Sound Lower the volume, increase goodwill YVAA YVAA Optimized YVAA Optimized with Attenuation Options Ordinary Chiller
15
Sound Level That You Can Control Our proprietary SilentNight technology automatically integrates with your BAS (or programmable) control to load shed BAS of load shedding provides “Night Set-Back’ for the neighborhood Effective when regulations require more stringent property line sound levels at night Johnson Controls15 Low Sound Lower the volume, increase goodwill YVAA YVAA Optimized YVAA Optimized with Attenuation Options Ordinary Chiller -10
16
For the Other 1% at Design Conditions: Property line restrictions will require attention to (worst case) design conditions sound levels Just like performance, the YVAA chiller allows you to tailor and tune sound reduction configurations to match your needs Johnson Controls16 Low Sound Lower the volume, increase goodwill
17
