YORK ups chiller capacity to 1225 kW

YORK’s YVAA air-cooled, variable-speed, screw chiller now available with capacity up to 1225 kW

Johnson Controls has increased the capacity of its YORK model YVAA air-cooled, variable-speed, screw chiller to 1225 kW.

Introduced in 2011, YORK says the YVAA chiller features the industry’s highest energy efficiency ratio (EER) at both full-load design and off-design conditions, when building loads and/or tower-water temperatures are lower.

On replacement projects, YVAA energy performance can exceed that of older chillers by as much as 30 per cent, while performance on new projects can exceed other manufacturers’ chillers by up to 17 per cent.

The YVAA chiller offers flexible energy consumption: it can be configured to offer design efficiency up to 3.4 EER, and a European Seasonal Energy Efficiency Ratio (ESEER) up to 4.8 EER.

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.

These sustainability advantages give building owners the opportunity to earn points in the Leadership in Energy and Environmental Design (LEED) green-building certification programs.

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.
