Heat Pumps

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.

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.

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.

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.

An analysis by Eon and Aachen University shows how quickly heat pumps with and without photovoltaic systems and storage pay for themselves in different types of homes, also in comparison to gas heating. A heat pump with photovoltaics is usually more economical than without. Balcony solar usually pays for itself in three to six years. An accompanying survey shows that most people underestimate the economic viability of climate-friendly energy technologies.

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.

Scientists in the UK developed a controller for B2B trading platform that considers thermal and visual comfort. Their modeling shows that participating in local energy trading increases the robustness of the control systems in residential microgrids in face of uncertainty in the occupant comfort level.

The Chinese manufacturer said its new photovoltaic air conditioner is available in three versions with a cooling capacity ranging from 12.1 kW to 16 kW and a heating capacity of 14 kW to 18 kW. It can be used for both residential and 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.

ABB says it has launched a smart panel for home energy management in partnership with Lumin, featuring software to control solar, batteries, and electric-vehicle chargers.
