heat pump

Scientists in Switzerland have created a system-dynamics model for the adoption of PV and heat pumps in Swiss residential buildings up to 2050. They have examined several scenarios to see how the incentive for PV affects heat pump adoption and the other way around, and they have concluded that strong regulatory changes are necessary to completely decarbonize the residential sector.

Researchers simulated the United Kingdom’s heat pump rollout through 2050, finding that expansion strategies could help to mitigate high energy prices. They used the UKENVI computable general equilibrium (CGE) model of the UK economy to project a range of scenarios.

The Chinese manufacturer said its new Heco series uses propane (R290) as a refrigerant and includes five models with a nominal capacity ranging from 6 kW to 17 kW.

UK-based Wondrwall says its new heat pump has a coefficient of performance of up to 4.99, with an inlet-outlet temperature of 30 C to 35 C. The system is based on the company’s AI-powered Home Energy Management System (HEMS) to efficiently manage household energy flows.

The Sweden-based heat pump provider said its new product is one of the slimmest and most compact system available on the market to date.

Wider use of electric heat pumps to heat buildings creates a larger market for renewable energy, but also presents challenges, which can be met through building insulation and weatherization, cold climate heat pumps, thermal energy storage systems, and higher-voltage distribution grids, a report says.

A European research team proposed a new air-source heat pump sizing approach that utilizes long-term climate data and adjusts system operation based on actual local climate conditions. The sizing algorithm incorporates peak heat demand, unitary final energy demand, and seasonal heat demand across different house sizes.

New research from Germany shows that identifying the cheapest residential heating source remains challenging, as the final results depend on the assumptions made and energy prices. The scientists, however, demonstrated that air-water heat pumps and gas heating systems are currently the most cost-effective solutions.

The German government has awarded a €310 million ($336 million) funding package to chemical manufacturer BASF for the construction of an industrial heat pump with a capacity of up to 500,000 metric tons of steam per year. It will use waste heat from steam crackers for CO2-free stream production. 

Researchers in Denmark have found that using a large-scale air-to-water heat pump in solar district heating may significantly reduce its levelized cost of heat. The proposed system configuration was simulated for an existing district heating plant in Denmark and was found to improve the flexibility of the system in response to energy prices.
