Johnson Controls introduces the YORK YVAA air-cooled variable-speed screw chiller, which can be tailored and tuned to offer superior efficiency, reduced sound and greater sustainability.
Featuring the industry’s lowest kW/Ton at both full-load design and off-design conditions, the YVAA chiller ensures efficient operation under all operating conditions. On replacement projects, YVAA energy performance can exceed that of older chillers by as much as 50 per cent, while performance on new projects can exceed competitors’ chillers by up to 25 per cent. In addition, the chiller’s performance can be tailored and tuned to hit specific targets for state, municipal or utility rebates, where available.
The YVAA chiller also offers flexible energy consumption, with design efficiencies up to 11.6 EER. The unit can also be configured to deliver an integrated part load value (IPLV) up to 19.8 EER.
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 optimised for sound performance, the YVAA chiller can reduce ambient noise by as much as 16 dBA at off-design conditions.
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 micro channel condenser coils reduce the refrigerant charge by as much as 15 per cent. Water, too, is handled responsibly, since no cooling tower is required. And because power generation is a major water consumer, the high efficiency of the YVAA chiller conserves water.
Seemant Sharma, Director & General Manager, Engineered Systems said, “For building owners seeking to go “Green” Equipment standards are an important issue and as a major HVAC equipment manufacturer with York brand we bring the highest efficiency standards and real world energy savings for the owners.” 
