In January 2025, Carrier welcomed Juliet Loiselle, Publishing Editor from Heat Pumps Today, and other members of the press to an exclusive event in Lyon, showcasing its latest in innovation and introduced its newest heat pump, the AquaSnap® 61AQ
Carrier’s Montluel facility in Lyon serves as one of the company’s four centres of excellence across Europe. Spanning 7,500m2, the research and development laboratories boast state-of-the-art equipment capable of simulating a wide range of operating conditions encountered by Carrier’s heat pumps. With 15 test rooms equipped with over 1,200 measurement sensors, the facility provides rigorous testing.
The AquaSnap® 61AQ is Carrier’s first high temperature air source reversible heat pump for commercial applications that uses R-290, a natural refrigerant with nearly-zero Global Warming Potential (GWP).
The Heat Pump has been specifically designed and optimised for R-290, combining Carrier’s innovative engineering with features that deliver high temperatures, increased energy efficiency, noise reduction, and enhanced operational performance. It can deliver high-temperature heating up to 75°C at outdoor temperatures as low as -7°C and operates efficiently in extreme conditions down to -25°C.
On reducing Environmental Impact, Didier Genois, Vice President and General Manager, Carrier Commercial HVAC, EMEA says “With its advanced component design and ultra-low GWP R-290 refrigerant, the AquaSnap® 61AQ helps businesses reduce energy bills while cutting carbon emissions.”
Applications
- High-temperature heating, multi-zone comfort heating, and domestic hot water with built-in legionella prevention.
- Suitable for new build projects and modernisation and retrofit projects.
- Can deliver tailored solutions for a large range of applications including hotels, healthcare facilities and collective dwellings.
Technical Innovations
- An air-source reversible heat pump with heating mode in the winter and cooling mode in the summer. It produces domestic hot water (DHW) all year long and has a legionella prevention cycle.
- Carrier developed a design around R-290 properties and integrated advanced inverter compressors and variable-speed fans for optimised efficiency and durability.
- The unit features noise reduction technologies for quiet operation in sensitive environments.
Safety
- Low refrigerant charge – less than 4kg/circuit.
- All refrigerant components are grouped into a dedicated insulated enclosure.
- Drive, pump and fans non-ignition source and placed out of the flammability zone and no brazing connections outside box limit the risk of refrigerant in the atmosphere.
- Refrigerant separator and water anti-freeze relief valve to avoid refrigerant in water loop in case of leakage. Optional leak detector sensor for quick alert in case of leakage.
