Trane debuts air-to-water heat pumps
The new products use propane (R290) as a refrigerant and have heating and cooling capacities ranging from 8 kW to 30 kW.
Hybridizing PVT energy with heat pumps, borehole storage
A European research group has tested an energy system combining PVT collectors, a water-to-water heat pump and borehole thermal energy storage in an Italian swine farm and has found the proposed system can completely replace fossil fuel-based power generation.
Façade-integrated R290 split-type heat pump for domestic hot water
Researchers in Austria have developed a new heat pump system for residential applications that reportedly achieves a coefficient of performance ranging from 2.82 to and 3.11 at an outdoor air temperature of 10 C and 20 C, respectively. They also found the system was able to supply the comfort conditions at all tested outdoor temperatures.
