The new heat pumps use R-454B as a refrigerant and are specifically designed to be matched with Johnson Controls’ residential gas furnaces. Their size ranges from 1.5 tons to 5 tons and their coefficient of performance (COP) spans between 3.24 and 3.40, according to the manufacturer.
Researchers at Germany’s Frauhofer ISE have analyzed the performance of a residential heat pump connected to a rooftop PV system relying on battery storage and have found that this combination significantly improves the performance of the heat pump while also increasing considerably the solar array’s self-consumption rate.
The US-based manufacturer said its new heat pump system has 5-ton capacity and a coefficient of performance of up to 3.95. It uses difluoromethane (R32) as the refrigerant and relies on DC inverter enhanced vapor injection (EVI) technology.
Sixty-one heat pump industry chiefs have signed a letter to European Commission President Ursula von der Leyen, warning that delaying the EU Heat Pump Action Plan jeopardizes a key net-zero European industry.
Heat pump sales in Germany rose by more than 50% for the second year in a row in 2023, according to new figures from Bundesverband Wärmepumpe (BWP).
New research from Austria has compared different industrial heat-generating techniques and has found that wind or solar-powered heat pumps are the cheapest and most environment-friendly solution.
€2.9B French tax credit, approved by EU, boosts solar manufacturing and net-zero equipment, aligning with Europe’s climate goals until 2025.
US-based Johnson Controls says its new 1,406 kW compound centrifugal heat pump is able to deliver high-temperature hot water as high as 77°C.The system reportedly has a combined coefficient of performance of 4.9.
Scrapping size limits on outdoor compressor units and removing location restrictions are just two of the eight policy changes the United Kingdom government should consider in its campaign to install 600,000 heat pumps by 2028, according to consultancy firm WSP.
Scientists have utilized two blower fans with two roll-bonded bare plates to create a heat pump that can operate in variety of ambient temperature and solar radiation conditions. The system has an average daily coefficient of performance of 3.24.
