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

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

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
Micro Channel Condenser CoilsLightweight, robust and easily cleaned
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
