The YORK YVFA free-cooling, air-cooled screw chiller combines variable-speed drive (VSD) screw compressors with integrated waterside economizer "free cooling" into a simple-to-operate package that is AHRI-certified. YVFA is available in nominal sizes from 150 to 450, delivering more than 2,110 kW at higher liquid temperatures. With intelligent controls, the free-cooling coils reduce the mechanical cooling load at a much higher ambient temperature, allowing the VSD compressors to reduce speed and energy use more hours of the year. YVFA combines control strategies with mechanical advances to further enhance performance at all conditions. Mechanical improvements include variable volume ratio compressors and VSDs for both the compressors and fans.
