To support decarbonizing industrial applications that require high temperatures or indirect steam production, Johnson Controls has launched a new hydrocarbon heat pump line, Sabroe HitemHP, delivering outlet temperatures of up to 122°C (252°F), according to the company.
The series comprises 10 models, with heating capacities from 100‒1,000kW (28.4‒284.3TR). The line offers two hydrocarbon refrigerant options, including butane (R600), with a maximum outlet temperature of 122°C, and isobutane (R600a), with a maximum outlet temperature of 107°C (225°F).
“Until now, electrifying high-temperature heat has been one of the hardest problems to solve,” said Steve Bell, Vice President and General Manager of Industrial Refrigeration at Johnson Controls. “With our new Sabroe high-temperature heat pumps, [we are] delivering a breakthrough solution that can help critical industries and institutions secure their energy future, significantly cut operational costs and align with the ambitions of Europe’s Clean Industrial Deal.”
The specifications: The factory-assembled water-to-water HitemHP packaged line features Sabroe SMC single-stage reciprocating compressors with variable-speed drive (VSD).
With a 50°C (122°F) heat-source water inlet temperature, the units produce 105‒514kW (29.9‒146.2TR) of heating capacity at a 120°C (248°F) outlet temperature, with COPs of up to 3.0 and refrigerant charges of 10‒51kg.
At the same 50°C inlet temperature, the units produce 199‒976kW (56.6‒277.5TR) of heating capacity at a 103°C (217°F) outlet temperature, with COPs of up to 4.3 and refrigerant charges of 20‒97kg.
Efficiency/flexibility/safety: “Under part-load operation, [HitemHP] can achieve up to 20% higher COPs than when operating at full capacity,” Johnson Controls said.
The Sabroe SMC compressor can also extend service intervals by nearly 50%, the company said.
The system can operate across a wide range of heat-source conditions, modulating capacity from 100% down to 18% to match the facility’s heating demand, according to Johnson Controls.
The line’s A3 refrigerant safety measures include leak detectors with siren and flashing alarm lights, as well as an ATEX ventilation system.
Other news: Johnson Controls is building new production spaces and launching new products to meet the European demand for sustainable heating and cooling solutions.
In May the company completed the expansion of its manufacturing facility in Aarhus, Denmark, adding 2,300m2 (24,560ft2) of new production space and a 1,800m2 (19,375ft2) customer experience and test center. The facility manufactures custom Sabroe heat pumps and chillers, including products using ammonia (R717), CO2 (R744) and propane (R290).
In February, it introduced an air-to-water York-brand YAS R290 heat pump model to the European market, capable of supplying cooling, heating or simultaneous cooling and heating. The units, which use 6.1 or 8.1kg of propane, offer heating capacities ranging from 86.7 to 139kW (24.7 to 39.5TR) and cooling capacities from 66.3 to 110kW (18.9 to 31.3TR).
Quotable: “A wave of growth across pharmaceuticals, biotechnology, advanced manufacturing, and food and beverage processing is driving demand for tighter, more energy-intensive operating conditions,” the manufacturer said. “HitemHP’s features and range reflect input from customers who partnered with Johnson Controls experts at the company’s testing facility in Holme, Denmark.”
“With our new Sabroe high-temperature heat pumps, [we are] delivering a breakthrough solution that can help critical industries and institutions secure their energy future, significantly cut operational costs and align with the ambitions of Europe’s Clean Industrial Deal.”
