heat pump

The Danish manufacturer said its novel CO2 heat pumps can reach a water inlet temperature of 40 C and a water outlet temperature of 95 C. The systems have purportedly a combined coefficient of performance of up to 5.56.

Developed at the U. S. Ames National Laboratory, the novel magnetocaloric heat pump utilizes gadolinium as the working medium and reportedly matches current vapor-compression heat pumps for weight, cost, and performance. The system is based on a packed-particle bed active magnetic regenerator, a magnetic source composed of permanent magnets and high permeability magnetic steel.

Swiss-based Hive Power has launched Flexo to optimize grid-connected devices, enabling flexibility in markets with dynamic tariffs. The Flexo solution has interfaces to integrate inverters, home energy management systems, charging point managements systems, meters, and other internet of things (IoT) devices.

Carrier, a US-based heating solutions provider, has introduced a new 4-14 kW line of heat pumps with a coefficient of performance of up to 4.90. The system use propane as the refrigerant and can reportedly reach leaving water temperature of 75 C.

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.
