heat pump

A scientific group has proposed adding thermal solar panels to air-source heat pumps while also using grid heating to keep temperatures stable at night. The group modeled a system that could reportely achieve a coefficient of performance of 10.11 and represent an optimal solutions for cold climates.

Panasonic has launched its new R32 heat pumps, introducing the EXTERIOS Z and ClimaPure XZ series. The models offer heating capacities ranging from 10,900 Btu/h to 28,800 Btu/h, depending on specifications.

Adveco has released 65 kW and 110 kW heat pumps, capable of scaling up to 1,760 kW by controlling up to 16 systems from a single unit. The pumps feature R32 refrigerant circuits.

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.
