Johnson Controls Launches Energy Efficient Heat Pump


Johnson Controls, the global leader for smart, healthy and sustainable buildings, announced the launch of the next-generation YORK® YMAE Air-to-Water Inverter Scroll Modular Heat Pump – a high efficiency air-to-water heat pump for the North American market. The YORK YMAE is a sustainable, future-ready solution for offices and schools that want to minimize their environmental impact and electrify their heating and cooling. The YORK YMAE uses R-454B, a refrigerant that cuts climate impact by nearly 80% compared with R-410A refrigerant. The YMAE will be offered in single and packaged-module configuration.

“The YORK® YMAE heat pump is a proven industry leader around the world, and we’re proud to further optimize its design and make it available to a new market,” said Andrew Graybill, director of product management for air-cooled chillers, Johnson Controls. “Its efficient performance and low-GWP refrigerant will empower customers in North America through a sustainable, future-ready heating and cooling solution.”

By utilizing low-GWP R-454B, the YMAE is compliant with upcoming regulations by the U.S. Environmental Protection Agency (EPA) through the American Innovation and Manufacturing (AIM) Act. The AIM Act directs the EPA to phase down hydrofluorocarbon (HFC) production and use by 85% over the next 15 years, with the next major phasedown going into effect Jan. 1, 2024. In addition to the YMAE, YORK will use R-454B across all its scroll compressor products. As a global leader in sustainability, Johnson Controls was a strong voice in support of passage of the AIM act and works hard to advance policies that spur the kinds of clean technologies that can tackle climate change.

Using the award-winning YORK Amichi platform as a foundation, the advanced YORK YMAE features all new hardware, including new-to-market, electronic vapor injection (EVI) scroll compressors, updated heat exchangers and an optimized frame. EVI technology significantly improves system capacity and efficiency and allows the YMAE to provide high water temperatures at low ambient conditions.

Highly flexible, the modular YMAE features two-pipe and four-pipe versions and serves a wide range of applications. The four-pipe system makes it possible to simultaneously heat and cool different areas of a building by moving heat from one area to another, improving efficiency and occupant comfort. The heat pump’s modular design makes it possible to multiply capacity with a minimal footprint. Up to four modules can be kitted together, factory-tested and shipped as a single unit, simplifying installation and speeding up commissioning. The YMAE joins the YORK family of heat pumps which serve applications that range from small commercial buildings to district heating, and is part of the OpenBlue platform of connected equipment.

The YORK YMAE will be available on a short lead time. Units will be available to order and begin shipping this year. Product details can be found in Johnson Controls Solution Navigator, a one-stop, real-time platform that speeds up and simplifies the building management process and makes it easy to find products that best meet application needs.
