Johnson Controls, Inc. has increased the capacity of its YORK model YVAA air-cooled, variable-speed screw chiller to 350 tons.

 

Introduced earlier this year, the YVAA chiller features the industry’s highest energy efficiency ratio (EER) at both full-load design and off-design conditions for efficient operation at all operating conditions. On replacement projects, YVAA energy performance can exceed that of older chillers by as much as 50%, while performance on new projects can exceed other manufacturers’ chillers by up to 25%. The YVAA chiller offers flexible energy consumption: it can be configured to offer design efficiency up to 11.6 EER, and an integrated part load value (IPLV) up to 19.8 EER.

 

Lower energy consumption means lower greenhouse gas emissions from the power plant. The YVAA chiller uses HFC-134a refrigerant, which has no phase-out date and an ozone-depletion potential of zero. Fewer joints and potential leak points keep the refrigerant inside the system, while a proprietary falling-film evaporator and advanced microchannel condenser coils reduce the refrigerant charge by as much as 15%. These sustainability advantages give building owners the opportunity to earn points in the LEED®green-building certification programs.

 

The YVAA chiller provides superior sound performance. In addition to a variety of sound-attenuation options, the YVAA offers its SilentNight feature, which works with a BAS (or programmable control) to load-limit the chiller when noise reduction is a priority. When optimized for sound performance, the YVAA chiller can reduce ambient noise by as much as 16 dBA at off-design conditions.
