Johnson Controls has launched two large heat pumps in its YORK portfolio. The YMAE and YCPB are air-source heat pumps designed for light commercial operations such as small shopping centres, hospitals, hotels, office buildings and schools.
Both products use R454B low-GWP refrigerant, which the manufacturer says has already been proved in the YORK product range, and which anticipates the latest European regulations on F-gases in some heat pumps and air conditioners from as early as 2027.
Deepak Ramesh Bhat, product director for Chillers & Heat Pumps, EMEA and India, said:
Heat pumps are recognised as an efficient, sustainable, and increasingly affordable solution – for both heating and cooling – and can be critical in supporting Europe’s transition toward a cleaner, greener and more resilient and secure energy future. The introduction of these two new products reinforces Johnson Controls’ commitment to this goal.
YMAE Air-to-Water Inverter Scroll Heat Pump (45-300 kW)
The YMAE is a new-generation platform of the award-winning Amichi series, promising best-in-class energy efficiency and a wider operation range to match the toughest European climate conditions.
It combines an inverter scroll compressor, EC fans and a York Smart control system to adjust capacity output to changes in building load. It boasts increased seasonal efficiencies up to 4.06 (heating) and 4.72 (cooling) that far exceed both regulatory requirements and current industry levels, the firm says.
In addition, the Enhanced Vapor Inject (EVI) system is designed to enable YMAE to function at ambient temperatures down to -25 deg C and to provide up to 60 deg C hot water – surpassing traditional heat pumps which can achieve -15 deg C and 55 deg C at best, Johnson Controls adds. The first 130 kW will be available in the second quarter of 2024, followed by other model capacity in multiple phases.
YCPB Large Packaged Air-to-Water Scroll Heat Pump (300-700 kW)
The YCPB unit is specifically designed for low ambient heating applications, thanks to vapour and liquid injection large scroll compressors. It is intended to offer the same extended operating envelope as the YMAE, while ensuring heating capacity, efficiency, and hot water temperature at low ambient, the firm says.
The YCPB range is designed in two versions, the standard two-pipe, and the a four-pipe version for simultaneous heating and cooling applications. Both versions offer market-leading SCOP high efficiencies, the manufacturer notes, and will be available in Europe from the third quarter of 2024.
