Solimpeks presents air-to-water heat pump for residential, commercial applications
The Turkish manufacturer said its Varm BCP heat pump has a heating capacity of 3 kW at 20 C outdoor temperature and a coefficient of performance ranging from 3.62 to 4.48.
Woltair expands online heat pump, solar PV platform
After finding growth in its home market and Poland, Czech Republic-based Woltair raised venture capital to expand its heat pump and solar PV software platform, used by both installers and homeowners, into Germany and Italy.
Component sizing key for upscaling high-temperature heat pumps
A group of researchers has investigated how high temperature heat pumps may be upscaled for industrial applications and has found that larger setups promise higher efficiency. They also found that smaller setups show a better coefficient of performance resulting from design effects.
Rooftop PV reduces building retrofitting costs by up to 50%
Cambridge researchers have analyzed the benefits of installing a PV system on the roof of an apartment building in addition to energy refurbishment and have found that photovoltaics, especially if combined with heat pumps, makes retrofit projects more affordable.
Viessmann launches air-water heat pump for larger residential, commercial buildings
The Vitocal 250-A Pro boasts a flow temperature of up to 70 C, a heating output of up to 39.5 kW and a cooling output of up to 21.7 kW and according to the German manufacturer, it is one of the quietest of its kind on the market. Its coefficient of performance is 5.6.
Bosch unveils water source heat pumps for residential, commercial applications
Bosch Home Comfort has presented two new heat pumps series that can be used for both retrofits and new buildings. Both products have a size of a size of ½ to 6 tons and a coefficient of performance of up to 4.9.
Fraunhofer ISE presents propane heat pump with heating, cooling performance of 5.6
The German research institute said the new heat pump was developed in partnership with ZAE Bayern and Mafac E. Schwarz. The system uses propane (R290) as the refrigerant and is suitable for industrial processes with a temperature range of 50 C to 70 C.
Japanese researchers unveil solar chemical heat pump system for buildings
The novel heat pump concept combines solar energy with chemical storage and reportedly consume 75% less electricity than conventional heat pumps. The system relies on a battery and a heat storage tank that can be used either separately or simultaneously, depending on the outdoor conditions.
Combining residential air heat pumps with air-geothermal heat exchangers
Researchers in Italy have found that combining residential air heat pumps with air-geothermal heat exchangers may reduce power consumption by up to 30%. They tested the proposed combination using Matlab in a passive single-family building located in Valtellina, northern Italy.
Researchers propose new models for heat pump load forecasting in energy communities
Novel research from Germany and the USA has analyzed the impact of heat pump (HP) integration on the ability of day-ahead load forecasting in energy communities. Using different models, the scientists have also investigated whether HP loads should be forecasted separately from the rest of the household or both together.
