Engineered heat pump solutions tailored to the thermal demands of six core market sectors worldwide.
Office towers, hotels, hospitals, and retail complexes require reliable space heating and cooling with minimal noise impact. DaikinAir heat pumps deliver variable-capacity modulation that matches dynamic occupancy loads while maintaining strict comfort standards.
Data centers generate immense waste heat that can be captured and reused. DaikinAir heat pump systems provide precision cooling while recovering thermal energy for nearby buildings or district heating networks, improving overall PUE.
GMP-compliant manufacturing demands extremely tight temperature and humidity tolerances. DaikinAir heat pumps provide the thermal stability required for cleanroom environments, vaccine storage, and API production processes.
Municipal and campus district energy networks are transitioning from fossil fuels to large-scale heat pumps. DaikinAir high-temperature systems deliver supply water at 60-90°C from ambient, seawater, or waste heat sources.
Food and beverage facilities need simultaneous heating for pasteurization and cooling for product storage. DaikinAir systems provide both from a single platform, recovering waste heat from cooling processes to supply hot water.
Chemical, textile, pulp and paper, and mining operations require reliable process heat at temperatures traditional heat pumps cannot reach. DaikinAir high-temperature cascade systems deliver up to 120°C, replacing steam boilers in many applications.
In 2022, DaikinAir delivered a 4.2 MW water-source heat pump station for a municipal district heating network in northern Poland, replacing two aging 6 MW gas boilers that had served a residential area of approximately 2,800 households since 1994.
The system extracts thermal energy from a nearby river at 4-18°C seasonal range and delivers supply water at 72°C to the existing distribution network. Two DaikinAir cascade heat pump units operate with R-744 (CO2) on the high-temperature stage and R-290 on the low-temperature stage, achieving a weighted seasonal COP of 3.4 across the October-to-April heating season.
Post-commissioning monitoring over the 2022-2023 heating season confirmed annual CO2 emissions reduction of 3,200 tonnes compared to the previous gas boiler operation. The municipality reported a 28% reduction in thermal energy cost per MWh delivered. The project required an 800 kVA electrical supply upgrade, completed in coordination with the local utility over a 16-week timeline.

Heat pumps are not a universal replacement for all thermal systems. Understanding the operational boundaries of heat pump technology helps engineers specify the right solution for each application.
Current cascade heat pump technology delivers supply water up to 120°C. Applications requiring steam above 150°C (such as certain chemical reactors, sterilization autoclaves, and turbine-driven processes) still require combustion-based boilers or electric resistance heating. Our 2028 roadmap targets 150°C, but this remains in development.
Air-source heat pump COP decreases as ambient temperature drops. At -15°C ambient, typical COP falls to 2.0-2.5 compared to 4.5-5.2 at 7°C rated conditions. In climates with sustained temperatures below -20°C, supplemental heating or ground-source/water-source systems are recommended to maintain acceptable efficiency.
Replacing gas boilers with electric heat pumps increases site electrical demand. A 500 kW thermal output heat pump draws approximately 125 kW electrical input at COP 4.0. Facilities with constrained electrical supply or high demand charges should conduct a detailed utility impact assessment before specifying heat pump capacity.
