Daikin Applied announced updates to its Rebel Applied packaged rooftop HVAC system, known for its leading airflow and efficiency ratings, and compact footprint. Rebel Applied now comes with inverter scroll compressors, precision temperature and humidity control, and adaptive refrigeration technology, expanding its ability to provide unmatched energy efficiency and enhanced indoor comfort.
Rebel Applied packaged rooftop HVAC system, now with inverter scroll compressors. Driven by Daikin inverter technology, these new features boost Rebel Applied's already best-in-class efficiency. Unlike staged compressors that operate at fixed points, the inverter technology modulates compressor and cooling capacity continuously from 100 percent down to 15 percent so the system dynamically responds to match the load of a building. This means constant temperature and humidity control, which helps reduce energy use and operating costs while enhancing occupant comfort.
By continually adjusting to building load, Rebel Applied consumes less energy at part load to deliver an Integrated Energy Efficiency Rating (IEER) as high as 20, more than 40 percent above the ASHRAE 90.1 Energy Standard for Buildings. In addition, engineers and building owners can select either a lead-circuit or dual-circuit inverter compressor configuration based on their efficiency targets and performance goals — an industry first.
The addition of adaptive refrigerant control also allows Rebel Applied to intelligently manage refrigeration cycles to keep the system online and operating safely. On the hottest days or when loads are at their highest, the adaptive controls look at the entering and leaving refrigerant conditions, and modify the compressor and expansion valves to prevent overload and nuisance shutdowns. The supporting Microtech controller gives users the ability to monitor the system in real time as well, and regulate refrigeration performance to improve operation during extreme weather or occupancy events.
To complement the latest features, Rebel Applied is equipped with several indoor air quality (IAQ) technologies available as factory-installed options, including: UV lights to kill pathogens and prevent microbes from living in the unit, high-efficiency pre and final filtration to capture more contaminants, and humidifier grids that help produce ideal building environments.
