Environmentally Friendly Operation

Rebel Applied's heat pump technology uses electricity to move heat, rather than generating it directly, resulting in lower carbon emissions and a more environmentally friendly heating and cooling solution. Government financial incentives are available to encourage adoption of this technology. The system utilizes advanced variable speed compressors and electronic commutated motor fans for precise temperature control, minimized energy waste, optimal performance, sustainable operation, and a reduced impact on your building's financial budget.

Low GWP Refrigerant

With a GWP of 675, R-32 contributes significantly less to global warming potential compared to refrigerants like R-410A. An R-32 system can use up to 40% less refrigerant charge in certain applications, reducing refrigerant usage and potential environmental leaks. As a pure, single-component refrigerant, R-32 maintains its composition over time, allowing for easier field topping off and recharging. It can be reclaimed and recycled with a simple cleaning process.

GWP Comparison: A bar chart illustrates that R410A has a GWP of 2088, while R32 has a GWP of 675.

Industry-Leading Performance

Rebel Applied systems surpass competitors with an exceptional EER of 11.0 and a Class 6 air leakage rating (less than 0.5% at +/-6 static pressure). This translates to optimum cooling performance with significantly less energy consumption, leading to substantial cost savings for commercial and industrial establishments and a reduced carbon footprint. The 20.0 IEER rating further showcases unparalleled energy efficiency across a wide range of operating conditions, making Rebel Applied suitable for diverse applications from small offices to large commercial buildings.

Air Leakage Rating: ASHRAE Standard 111 Class 6 at +/-6 Static Pressure.

Advantages and Technologies

Sustainable Heat Pumps: Higher Capacities for Cold Climate Applications

Rebel Applied's Direct Expansion (DX) heat pumps are highly energy-efficient, transferring heat between spaces using a refrigeration cycle. This process requires less energy than traditional heating systems like electric resistance heaters or fossil fuel furnaces, reducing greenhouse gas emissions and overall carbon footprint. Unlike conventional heat pumps that struggle in cold climates, Rebel Applied utilizes boost compression to increase heating capacity, with supplemental heat available from gas or electric sources. Key benefits include high efficiency heat transfer, compact design for ease of installation, flexible zoning, reduced noise levels, and durable, reliable operation.

Heat Load vs. Outdoor Air Temperature: A graph shows that as outdoor air temperature decreases, building heating demand increases. Rebel Applied's heat pump capacity decreases at lower temperatures, requiring supplemental heat.

Capacity Comparison: A bar chart demonstrates that the 'BOOSTED HP' (Rebel Applied) offers significantly higher capacity than 'TRADITIONAL HP' in cold conditions.

Unlimited Packaged Configurability and New Split Condensing Systems

With a groundbreaking 37% shorter and 20% lighter design, Rebel Applied units offer flexible installation in tight spaces, ideal for new installations and retrofits. This compactness saves real estate, simplifies logistics, reduces project timelines and costs, and minimizes structural requirements. The modular solution provides unparalleled flexibility for custom designs. Experience easy installation with a no-transition curb for hassle-free integration. Rebel Applied's inverter scroll compressors operate at variable speeds, ensuring energy efficiency, significant energy savings, and precision air temperature and humidity control.

Inverter vs. Non-Inverter Control: A graph illustrates that inverter compressors maintain a stable supply air temperature setpoint, providing efficient temperature control, while non-inverter compressors result in inefficient, fluctuating temperature control.

Putting the IQ in IAQ (Indoor Air Quality)

Daikin technologies focus on ventilation that maximizes effective clean air changes with the lowest energy consumption to address IAQ issues like CO2 and VOCs. The Sorbent Ventilation Technology (SVT) is tested per ASHRAE 145.2 to remove CO2, VOCs, and other contaminants using sorbent filtration. When applied using ASHRAE 62.1's IAQ Procedure (IAQP), SVT provides cleaner air and reduces HVAC energy use by up to 30%. Benefits include better IAQ, increased occupancy flexibility, reduced outdoor air intake (up to 80%), and energy savings (up to 30%).

Pathogen Mitigation:

• Photo-Catalytic-Oxidation (PCO): UVGI photons react with a Titanium Oxide (TiO2) mesh panel to create hydroxyl radicals that oxidize gaseous organic compounds, odors, and VOCs.
• Filtration: Configurable filtration options include MERV 16 and HEPA final filters to reduce the risk of airborne pathogens.
• Ultra-Violet Germicidal Irradiation (UVGI): Factory-mounted UV lights are available for coil cleaning or airstream disinfection to deactivate airborne pathogens.
