heat pump

The Italian manufacturer said its new R32 heat pump has a coefficient of performance of up to 5.2 and a heating capacity of up to 16 kW. It is available in either single-phase or three-phase versions.

Researchers in the United Kingdom found that approximately 175 TWh of hydrogen and compressed air storage capacity will be needed to fully decarbonize heating in the United Kingdom. Lead researcher Bruno Cardenas told pv magazine that, when domestic heat demand is 100% electrified, average annual electricity demand and peak load in the grid are 26% and 70% higher than current levels.

The Japanese manufacturer said its new heat pump system features a coefficient of up to 5.42 and a seasonal energy efficiency ratio of up to 33.2

Scientists in Spain have simulated a system that uses both power-to-heat-to-power thermal batteries and lithium-ion batteries for energy storage. The hybrid system reportedly achieved a 7% lower LCOE compared to a PV system relying solely on lithium batteries, while simultaneously increasing PV self-consumption by up to 20%.

Heat pump manufacturers will need to meet ‘smart ready’ standards under new appliance regulations, including stricter rules on cybersecurity. Utilities will be obligated to ensure battery energy storage systems, heat pumps and electric vehicle smart charge points can work across different tariffs under tariff data framework.

The Germany manufacturer said its new heat pump systems use propane (R290) as the refrigerant and are able to provide a maximum flow temperature of 70 C. Their coefficient of performance ranges from 4.7 to 5.1.

Researchers in Italy have designed a novel carbon dioxide heat pump that can work with photovoltaic-thermal energy, a finned coil heat exchanger and a U-tube borehole heat exchanger. Their experiment has shown that the simultaneous use of at least two energy sources always results in improved system performance even with limited heat transfer areas.

Conceived for industrial applications, the novel heat pumps can reportedly deliver hot water at 65 C from -10 C up to 35 C of external air, and hot water at 55 C down to -20 C of external air. Their coefficient of performance reaches up to 3.60.

Scientists in China have developed a novel PV-powered cooling and heating system that combines a water-cooled gas cooler and an air-cooled gas cooler. The system went through a series of simulations and showed it can potentially achieve a coefficient of performance of up to 7.34.

Conceived for industrial applications, the Danae heat pump system is available in 10 versions with cooling capacities ranging from 22.1 kW to 156.9 kW and heating capacities spanning from 24.8 kW and 181.6 kW.
