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 reduction

in power consumption & your environmental footprint

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 cost

of 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)

Helps You Achieve BREEAM® Certification

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
