Johnson Controls, the pioneer for smart, healthy and sustainable buildings, is showcasing the YORK® Sun™ Choice Ultra High-Efficiency Rooftop Unit at AHR Expo 2023.
Available in 12.5-23 tons, the RTUs leverage a combination of Copeland™ high-efficiency ZPKZ fixed speed, ZPS two-stage, and ZPV variable-speed compressor technology to deliver the highest part-load efficiency in their class. YORK® Sun™ Choice Ultra High-Efficiency Rooftop Units surpass DOE 2023 efficiency standards by up to 45%.
Indoor air quality
Choice rooftop units are Smart Equipment enabled to further enhance efficiency
Choice rooftop units feature a convertible filter rack with pleated filters up to MERV 13 available as a factory option to help meet LEED requirements.
Multiple airflow strategies – including variable air volume (VAV), exclusive IntelliSpeed™ discrete fan control (DFC) with 2-stage and 4-stage options and Continuous Reset Single Zone (CRSZ) control – help to improve ventilation based on building requirements.
Additionally, the units are compatible with a full suite of system accessories to further support indoor air quality (IAQ) performance.
Choice RTUs lower initial project costs
In addition to operational cost-savings achieved through system efficiencies, Choice RTUs are designed to lower initial project costs as well.
The lightweight design streamlines specification by reducing building design requirements and eliminating the need for additional structural engineering analysis when used in replacement applications. The direct-replacement footprint is compatible with approximately 70% of the competitive installed base, minimizing the need for costly transition curbs.
Choice rooftop units are Smart Equipment enabled to further enhance efficiency, reduce operational costs and extend equipment life. This also provides seamless integration with building control systems, including Verasys®.
