heat pump

The Fraunhofer ISE has designed a novel method for assessing the potential of low-temperature heat sources for large-scale heat pumps. The five-step process was tested on the German city of Fellbach, enabling the identification of heat sources with LCOH lower than €0.1/kWh.

Frost & Sullivan says the future of the global heat pump market hinges on clear policies and supportive regulations, following a growth slowdown in recent years.

UL Solutions says it will expand heat pump testing at its facilities in Texas and Italy to meet rising demand in the heating, ventilation, and air conditioning (HVAC) industry.

The Italian manufacturer said its new Large Evo PL heat pump can achieve a seasonal coefficient of performance of up to 4.17. The system can also reportedly deliver water temperature of up to 60 C and, when stacked in series, reach a maximum system capacity of 1,660 kW.

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.
