The EU funded MultiPACK project tested Integrated CO2 heat pump systems in two Italian hotels and found COP values up to 6, depending on the ambient temperatures
Decisive action on short-lived climate pollutants such as HFCs is found essential to limit global warming in the next 25 years, with only decarbonization policies yielding results in the long run and overshooting targets in the near term.
But European Environmental Bureau contends that the proposal falls short by allowing f-gases in applications where natural refrigerants are available.
The major Australian supermarket chains have focused on transitioning to new refrigeration technology and have preferred to refurbish stores directly with new transcritical CO2 (R744) racks, rather than perform retrofits and prolong the life of existing assets with HFO blends. This assessment comes from “Cold Hard Facts 2021,” a review of the refrigeration and air-conditioning…
The four-year research project will study how to utilize surplus cold and heat and leverage thermal energy storage to reduce food industry emissions.
Stakeholders can submit comments on the European Commission’ proposal to decarbonise buildings until March 15.
The deadline for submitting comments is February 18.
New rules intend to reward the most energy-efficient technologies, such as efficient reversible heat pumps and district cooling networks.
The “negative list” includes refrigerators and freezers containing halogenated refrigerants.
The Austrian Association of Refrigeration (ÖGKT) has launched a training facility covering natural refrigerant technologies.
