Heat Pumps

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.

Researchers in Germany have developed a simulation software tool that visualizes heat flows in existing district heating networks and is capable of predicting load peaks. It can also be used to help plan and commission new grids.

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 European Bank for Reconstruction and Development (EBRD) is investing up to €105 million ($109.5 million) in a large-scale solar-thermal plant in Novi Sad, Serbia. The project is expected to reduce the district heating agency’s natural gas consumption by around 29%.

Researchers in Iran have used digital elevation models to improve the accuracy of solar energy potential maps. Their model is intended to identify the best areas for solar panel deployment in urban areas.
