Variable-speed screw chiller

The YORK YVWA water-cooled screw chiller by Johnson Controls.

04/19/2012


Johnson Controls has introduced the YORK YVWA water-cooled screw chiller. The design of this chiller, with energy-saving variable-speed technology, helps cut energy costs and carbon emissions by as much as 30%. The variable-speed drive saves energy during the 99% of operating hours spent at off-design conditions, when building loads and/or tower-water temperatures are lower. The YVWA increases sustainability by using HFC-134a refrigerant, which has zero ozone-depletion potential and no phaseout date. Its innovative design reduces the number of potential leak points by 35%. In addition, the company’s falling-film evaporator reduces the chiller’s refrigerant charge by as much as 30% compared to conventional designs.
