Daikin unveils series of residential air-to-air heat pumps
Daikin has released a line of residential air-to-air heat pumps, using difluoromethane (R32) as the refrigerant, with outdoor unit dimensions of 662 mm x 442 mm x 1022 mm. The output ranges from 2.5 kW to 3.5 kW, and the seasonal coefficient of performance (SCOP) is between 4.85 and 5.17.
LG launches residential air-to-water propane heat pump
The new product utlizes propane refrigerant with a lower global warming potential and has a seasonal coefficient of performance (SCOP) of over 5. According to the manufacturer, it can achieve a flow temperature of 75 C and 100% heating output at outside temperatures of -15 C.
Performance parameters for residential heat pumps linked to PV, storage
German researchers measured a PV-powered heat pump with battery storage in a single-family home in Freiburg, Germany, for a period of a year. It features smart grid-ready tech that adjusts operations based on the grid.
Infinite Turbine debuts heat pump turbine for homes, businesses
Infinite Turbine has developed a heat pump turbine for residential and commercial applications, using PV or alternative electricity sources for simultaneous cooling and hydraulic power. The tech can be retrofitted with existing CO2 heat pump systems for air conditioning, hot water, and process heat.
High-resolution model to identify hourly usage patterns of residential heat pumps
Developed by scientists from the UK and Spain, the new model uses high spatiotemporal resolution weather data and data from heat pump field trials. It finds “significant regional differences” compared to a British nation-wide estimation.
EDF acquires CB Heating
EDF has purchased UK heat pump installer CB Heating for an undisclosed sum.
Daikin lauches new air-to-air heat pumps
Intended for applications in commercial buildings, the new VRV 5 heat pumps have reportedly a 9.1% higher seasonal efficiency compared to the company’s previous models. The new products use difluoromethane (R32) as the refrigerant.
PV-driven microgrid for hydrogen, cooling
The University of French Polynesia has built a PV-driven hydrogen generation unit that combines a hydrogen chain with a thermochemical unit. The latter is used to recover waste heat from the electrolyzer and fuel cell to enable deferred cooling production for air conditioning.
LG targeting Alaska for heat pump deployment, research
LG has formed a partnership with the University of Alaska Anchorage to conduct lab research and perform real-world testing of heat pump technologies, with a particular focus on Alaska’s extreme temperatures.
Novel residential solar-assisted heat pump system integrates PCM for heat storage
A British-Chinese research group has developed a novel heat pump concept consisting of a heat pump, the PCM tank, and tube solar heat collectors. Intended for demand shifting in space heating and domestic hot water (DHW) applications, the system is reportedly able to achieve a higher coefficient of performance than conventional heat pumps.
