Press Release Summary:
Available in nominal sizes 150–450 yielding over 600 TR (2110 kW), AHRI-certified YORK YVFA Screw Chiller features air-to-liquid free-cooling coils that eliminate need for mechanical cooling when ambient conditions allow. Intelligent controls optimize energy use, constantly evaluating conditions and controlling bypass valves to reduce pump energy when free cooling is not available. For critical processes, Quick Start feature achieves full load after power loss in 4 minutes or less.
Original Press Release:
Johnson Controls Announces Industry's First AHRI-Certified, Integrated Variable-Speed Drive Screw Chiller with Free Cooling
New YVFA free-cooling air-cooled screw chiller offers lowest possible yearly energy consumption and lifecycle costs with payback in as little as two years
MILWAUKEE – The YORK® brand of Johnson Controls, the leader in air-cooled chillers with variable-speed drive (VSD) compressors, introduces the YORK YVFA free-cooling air-cooled screw chiller. Available in nominal sizes 150 - 450 yielding over 600TR (2110kW), the YVFA provides the industry with the first AHRI-certified, integrated variable-speed drive (VSD) screw chiller with free cooling.
The YVFA chiller was recently named a finalist in the Cooling category of the 2017 AHR Expo Innovation Awards competition, co-sponsored by ASHRAE and AHRI.
The chiller’s advanced technologies include VSD compressors that ensure efficient operation across all cooling-load and ambient temperature conditions. Its integrated high-efficiency, air-to-liquid free-cooling coils reduce or eliminate the need for mechanical cooling when ambient conditions allow. In addition, intelligent controls optimize energy use year-round, constantly evaluating conditions and controlling bypass valves to reduce pump energy when free cooling is not available. When a new setpoint is required, adjustment can be made at the chiller control panel or through a building automation system.
For critical processes, such as data center and critical-care facility applications, the chiller is equipped with a Quick Start feature that achieves full load after a power loss in four minutes or less. Variable-frequency inverter technology enables a zero-inrush start, reducing generator and switch gear sizing, and a high displacement power factor across the entire operating range. In addition, the liquid-cooled VSD keeps the electrical panel free of dust and dirt and operating at a standard ambient temperature up to 115 F/46 C.
The YVFA provides flexibility for all building chilled liquid loops by offering options for open-loop (glycol in building) and closed-loop (water in building) configurations. Saving energy is simple in every situation—mechanical, free-cooling or hybrid cooling mode. The hybrid mode uses advanced technologies to provide unsurpassed efficiency at part-load conditions.
The Johnson Controls Annual Energy Cost (AEC) tool produces customized reports, factoring in all key variables to confirm the chiller delivers the smallest possible energy footprint. The AEC illustrates that in most locations, a facility operating 24/7 with a constant cooling load can achieve an operating cost payback in as little as two years. Performance is ensured by AHRI certification.
