Mitsubishi Electric debuts new residential air-source heat pumps
The manufacturer has expanded its Ecodan R290 heat pump series with three new products. The systems use propane (R290) as the refrigerant and can purportedly deliver flow temperatures of up to 75 C.
Copeland invests in thermo-acoustic heat pump developer
The U.S. heating specialist has agreed to invest an unspecified sum in Dutch startup Blueheart Energy, which is developing a 6 kW heat pump that works on acoustic waves and is able to produce both heat and cold air.
Japanese energy supplier to use green hydrogen for district heating, power
Akasaka Heating & Cooling Supply says it will use green hydrogen produced at an unspecified location in Japan to produce heat and electricity for its Akasaka 5-chome district heating system in central Tokyo.
Heat pump control strategy for energy communities
Researchers have utilized measured data from a small energy community on a Finnish university campus to simulate its operation under various control strategies. The first control strategy prioritizes the use of heat pumps, while the second prioritizes price. Total costs were reduced by up to 25% with the second option.
Sprsun unveils air-source heat pump for swimming pools
The Chinese manufacturer said its new heat pump system has a heating capacity of 6.5 kW to 17 kW and a coefficient of performance ranging from 4.8 to 5.23 at 15 C.
PV-driven absorption cooling system for arid regions
Scientists in Saudi Arabia have simulated a solar-powered single-effect absorption cooling system that uses water-lithium bromide as a working fluid, under the environmental conditions of Riyadh. Exergy and exergy rates are calculated for each level of the system, with optimal generator performance being found to peak at 80 C.
Canadian government invests in heat pump subsidies for Manitoba
The Canadian government has announced further investment in the country’s heat pump subsidy scheme, which offers homeowners an up to CAD 20,000 ($21,695) payment towards heat pump installations, aimed at the province of Manitoba.
Thermocold launches new air-to-water heat pumps
The Italian manufacturer said its new heat pumps use R454B as a refrigerant and have coefficient of performance of up to 3.35.
Vaillant, Fraunhofer ISE present residential heat pump with new safety concept
The novel heat pump system relies on a thermal sensor based on an adsorbent-coated sensor layout developed by Vaillant in cooperation with the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). This technology is reportedly effective in preventing propane from forming an ignitable mixture with air outside the device.
Triple Solar unveils PVT-assisted heat pump using waste heat from PV
Triple Solar BV has developed a residential photovoltaic-thermal (PVT) heat pump that uses waste heat from PV modules, eliminating the need for an outdoor unit.
