Sustainability

Giant step forward,smaller footprint

Indirect Emissions Contribute 98% of Chiller GWP Electricity generation is the largest source

of greenhouse gas emissions

Efficiency of YVAA chiller offers substantial reductionin power consumption & your environmental footprint

Johnson Controls13

SustainabilityGiant 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 costof an air-cooled

Helps You Achieve LEED® Certification

Enhanced Refrigerant Management:Low refrigerant use ensures 2 points for Energy and Atmosphere Credit 4 (EAc4)

Optimize Energy Performance:Higher efficiency helps your building qualify for maximum pointsfor the Energy and Atmosphere Credit 1 (EAc1)

Low Sound

Lower the volume, increase goodwill

Off-Design Conditions Occur 99% of the Time

Most stringent sound requirementsoccur on evenings and weekends

Standard VSD compressorsdesigned for sound relief areduced speeds

Optional VSD condenser fanswill provide further significantoff-design sound benefit

Further accessories can providesound reduction at on-designconditions

VSD provides Soft start with no inrush: Starting current never exceeds full load amps.

Lowest maximum electricity demand costs Eliminates compressor starting thermal and

electrical stress No motor heating at start allows for quicker re-

start after power failure Stand by generator size reduced High (95%) displacement power factor

The VSD in YVAA provides 0.95 displacement power factor as standard.

Qualifies for rebates from electrical utility companies, which contributes to payback.

Variable Speed DriveImproves payback with lower electrical costs and rebates

Variable Speed CompressorReliability through simplicity

Proven reliable compressor

52% fewer moving parts 35% fewer leak points

Automated machining of rotors

High precision ±4 microns Frick design and manufacture

DX Evaporator:

Water outside the tubes Refrigerant inside the tubes Water connection at sides

Evaporator Technology

Flooded Evaporator:

Water inside the tubes Refrigerant outside the tubes Water connection at ends

Johnson Controls33

Falling Film EvaporatorIncorporates best elements of the DX and Flooded styles

Hybrid Falling Film Evaporator: Water is inside the tubes; Refrigerant is outside the tubes Two bundles of water tubes

Upper bundle is covered in a film of refrigerant Lower bundle is flooded in the refrigerant

Johnson Controls34

Micro Channel Condenser CoilsLightweight, robust and easily cleaned

All Aluminum tubes, fins, and headers Better heat transfer per volume of coil

Johnson Controls35

Lighter weight of aluminum lowers the overall chiller weight: Save costs of roof reinforcements and lifting equipment

Reduces the amount of refrigerant used. The quantity of R134a used in the chiller allows to qualify for 2 LEED EAc4 points


Johnson Controls36

All aluminum construction minimizes the opportunity for galvanic (dissimilar metal corrosion

Increases the chiller life and limits the degradation of performance over time The fins do not extend past the tubes making it easier to clean with water spray

without bending the fins. Microchannel coils are less deep, allowing complete washing without dirt being

trapped inside the coils
