The South Korean heating specialist said its new heat pump system can achieve a seasonal coefficient of performance of up to 4.79 and flow temperatures of up to 75 C.
TWL unveils PVT panels for ground-source heat pumps
The German specialist for solar thermal energy and heat storage said its new PVT collectors rely on double-glass and monocrystalline TOPCon cells. The product has a power conversion efficiency of 22.5% and a maximal thermal ouput of 1,100 W.
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.
