Toshiba Carrier has been recognized at the 2023 National Invention Awards of Japan for its innovative discharge port structure in multi-cylinder rotary piston compressors for heat pumps. The technology tackles the problem of overheating, resulting in improved heating capacity and efficiency.

More than 20 companies, governments, and nongovernmental organizations have presented EU Energy Commissioner Kadri Simson with a roadmap for the European heat pump sector, including recommended solutions to overcome barriers to growth.

Sonnen has introduced a new software solution to seamlessly integrate heat pumps into private household energy supplies and enhance grid stability. The company’s initial partner is heat pump manufacturer NIBE, but additional partners are expected to join in the future.

Daikin Applied Americas has developed an air-to-water heat pump that can produce 91.2 kW of heat and 23.58 tons of cooling. The new device can be used as a cascade system with water-to-water heat pumps, and can switch between cooling and heating modes, depending on temperature requirements.

Developed by Chinese researchers, the system is designed to reach a heating capacity of 5.7 kW and an overall coefficient of performance of 1.40 at nominal conditions. It is made with an engine unit, a heat pump unit, and a gas resonator unit in a loop.

The European Commission has opened a call for evidence on its plan to accelerate heat pump roll-out across the European Union. It is asking citizens and businesses for feedback on four strands of action, focusing on financing, legislation, skills, research and innovation. The call for feedback is open until May 26.

The US authorities will offer new funds under the US Inflation Reduction Act (IRA) to build a clean energy economy, create new manufacturing jobs, and help families to save money on their energy bills.

Viessmann’s new sub-distribution system links various components and connects them to the power grid. Its Wallbox has a charging capacity of 11 kW (three-phase) and is equipped with a 7.5-meter “Type 2” charging cable.

PV deployment is gathering pace in the EU member state but grid capacity shortfalls and unpredictable shifts in government policy need to be addressed if the nation is to harness its full solar – and European energy security – potential.

The Polish government says it will launch the fifth round of its Mój Prąd program in April. The scheme will offer rebates for air and ground heat pumps, as well as residential batteries.
