Johnson Controls Inc. has increased the capacity of its YORK model YVAA air-cooled, variable-speed screw chiller to 350 tons. The YVAA chiller can be configured to offer design efficiency up to 11.6 EER, and an integrated part load value up to 19.8 EER. The YVAA chiller uses HFC-134a refrigerant, which has no phase-out date and an ozone-depletion potential of zero. A proprietary falling-film evaporator and advanced microchannel condenser coils reduce the refrigerant charge by as much as 15%. 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.
