Researchers found that a MAN CO2 high-temperature heat pump could reduce its electricity consumption by 7MW in just 30 seconds
CO2 heat pumps could provide both potable water and cooling for district cooling systems.
The heat pump will be used for process heating and medium-pressure steam generation and could be commercially available by 2027.
The heat pump had an energy efficiency ratio of 4.59 for cooling and a coefficient of performance of 4.59 for cooling under partial load.
The prototype, developed by German professor and researcher Stefan Elbel and his team, was also found to offer a 14% increase in capacity.
Technical advancements show that the potential of R744 in district heating systems exceeds what traditional refrigerants can offer, according to Bitzer.
The Danish company says heat pumps can beat biomass boilers in heating price and payback period.
The system, which also includes a large storage tank and an electric boiler, is reducing energy cost by 59% in every MWh of heat compared to a biomass boiler.
Partner Fieuw Koeltechnik plans to install the PX G1300 device at five other stores and a pancake factory.
In a simulation, the Italian manufacturer’s adiabatic system reduced power consumption by 70%, boosting COP by 80%, compared to a dry gas cooler.
