Daikin Applied Adds Air Source Heat Pumps to Premier Rooftop Systems

Daikin Applied announced the addition of air–source heat pumps to its lineup of Rebel and Rebel Applied packaged rooftop systems. With electricity-powered heat pumps, low-GWP R-32 refrigerant and ultra-efficient inverter compressors, the new Rebel Applied and Rebel units will help building owners optimize comfort and cost while decarbonizing their facilities. The units also include features that increase performance, especially in cold climates, and simplify installation for both new construction and retrofits.   

Featuring inverter compressors, Rebel Applied and Rebel rooftop units are proficient in lower ambient temperatures. This is accomplished with additional outdoor coil surface and a supplemental compressor that kicks in when temperatures drop. Compressors have a boost function that ramps speeds up in cold conditions to increase heating capacity. The new units have optional features such as energy recovery wheels to pre-heat air before it passes through the heating coil, extending the heat pump’s capacity. 

By using configurable circuitry, and isolating new loads to smaller and separate circuits, Rebel Applied and Rebel heat pumps eliminate or minimize electrical infrastructure modifications, trimming installation time and associated expenses. Further, the rooftop systems offer auxiliary electric heat limits and emergency backup controls that reduce the unit’s peak design electrical load. Designed with R-32, the rooftop units are up to 20% more efficient than predecessors with R-410A refrigerant. These new solutions are ideal for schools and commercial office spaces where there are common needs for comfort and space conditioning.
