Johnson Controls has increased the capacity of its York model YVAA air-cooled variable-speed chiller to 350 tons. Introduced earlier this year, the YVAA chiller features the industry’s highest energy efficiency ratio at both full-load design and off-design conditions for efficient operation at all operating conditions, according to the company. YVAA energy performance can exceed older chillers as much as 50 percent, while performance on new projects can exceed up to 25 percent, officials said. The chiller is designed to offer flexible energy with efficiency up to 11.6 EER and an integrated part load value of up to 19.8 EER,. The chiller also features the SilentNight system, a programmable control for noise reduction.
