AI control tech to improve coefficient of performance of air source heat pumps
Scientists from South Korea have developed a heat pump optimization technique that controls the secondary refrigerant flow. The proposed technology offers the advantage of bypassing the need to control the compressor of the heat pump, which is a function that is commonly not available in commercial devices.
‘We have not forgotten how China’s unfair trade practices affected our solar industry’
The president of the European Commission, Ursula von der Leyen, said in the 2023 State of the Union Address this week that European solar manufacturers face stiff competition from heavily subsidized Chinese rivals and noted that the bloc is launching an anti-subsidy investigation into electric vehicles from the country.
PV-driven heat pump system for freshwater production, cooling, hot water
Scientists in India have combined a solar-assisted heat pump with a humidification-dehumidification and vapor compression refrigeration (HDH-VCR) cycle to generate heat and cooling. The system is reportedly able to generate up to 5.5 l per hour (LPH) of fresh water while achieving an ‘enhanced’ coefficient of performance.
REC launches 470 W heterojunction solar panel with 22.6% efficiency
REC has developed a new series of heterojunction solar panels with efficiencies up to 22.6% and an operating temperature coefficient of -0.24% per degree Celsius.
The Hydrogen Stream: Liquid hydrogen test flight could enable long-distance flights
H2FLY claims that a recent three-hour test flight, entirely powered by liquid hydrogen, could lead to sustainable long-range flights fueled by liquefied, cryogenic hydrogen. Solaris, meanwhile, has started selling hydrogen buses in Italy.
