New refrigerant may improve coefficient of performance of air-source heat pumps by up to 21%
Developed by a Chinese research group, the novel refrigerant is made of a mixture of carbon dioxide (CO2) and a non-flammable hydrofluoroolefin. It has slightly higher costs compared to conventional compounds, but its creators claims these costs could be significantly reduced with large-scale industrial production.
Netherlands’ largest wastewater heat pump goes online in Utrecht
The largest heat pump in the Netherlands is now online at the Utrecht sewage treatment plant. It generates heat up to 75 C for the local network by using purified hot wastewater from a regional water authority.
Ice-source heat pump system for residential applications
UK scientists designed a new heat pump concept that they claim could be particularly beneficial to newly developed areas or potential residential complexes. The system uses ice or ice slurry as the heat source and its energy consumption is reportedly lower than that of several types commercially available heat pumps.
