heat pump

The proposed system uses waste heat by thermally coupling a water lithium bromide absorption heat transformer with a water vapor compression heat
pump. It reportedly achieved a temperature elevation of up to 110 C and ultra-high temperature heating of up to 180 C.

The Chinese manufacturer said the latest version of its Phnix HeatMaster heat pump series enables seamless integration with PV arrays. The systems have a coefficient of performance of up to 5 and can reach an outlet water temperature of 75 C.

The European Heat Pump Association (EHPA) says there are no value-added tax (VAT) advantages for heat pump installations in terms of upfront costs in most European countries. It is calling for EU member states to use available fiscal tools to make installations more financially viable.

A British-Swedish research team has reviewed all models for designing and simulating solar-powered heat pumps systems of various complexities. Based on this work, the scientists proposed a new method combining five models across multiple computer programs into a single analysis tool that reportedly produces accurate critical metrics for technical, economic, and climate impact analysis.

Scientists have designed a novel control approach for water-to-water heat pumps that use carbon dioxide. They relied on a virtual heat pump for their tests. The coefficient of performance (COE) improved by up to 14.6%.

The Korean manufacturer said its new products are now available in the North American market and are suitable for multi-unit homes, apartments, new-builds and retrofits. The systems work with new AI technology and reportedly perform better when connected to a PV system.

The new government of Jordan has been described by analysts as progressive on clean energy. Public support for solar has already been widespread, with tariffs for home systems encouraging people to adopt low-cost energy.

The Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) and EDF are leading an international consortium developing AI-driven heat pumps that adapt to environmental conditions and learn from changing circumstances.

Daikin has released a line of residential heat pumps, using propane (R290) as the refrigerant, with outdoor unit dimensions of 1,122 mm x 1,330 mm x 600 mm. The new products have an output ranging from 6 kW to 14 kW and can reportedly deliver hot water up to 75 C.

A report from the European Heat Pump Association finds evidence of grants, loans or tax rebates for industrial-sized heat pumps across the continent but calls for barriers to further installations, such as a lack of awareness of their potential, to be addressed.
