The Polish manufacturer Corab has developed a new geothermal heat pump with several components supplied by the Danish Danfoss. It offers between 8 kW and 16 kW of nominal thermal power.
Corab has introduced a residential saltwater heat pump that can reportedly provide domestic hot water (DHW) and cooling and heating (CH) at temperatures up to 65°C.
“We produce this new heat source in our facilities in Poland with some components supplied by the Danish technology company Danfosss,” he told pv magazine Filip Odrobinski, Sales Director. “Danfoss supplies the compressor, exchangers, condenser and evaporator. It also supplies the temperature and pressure sensors, as well as the controller and expansion valve.”
The company offers the heat pump in three versions, with 8 kW, 12 kW and 16 kW of nominal thermal power.
The smallest model measures 700 mm x 600 mm x 1,820 mm and weighs 87 kg. It offers a seasonal coefficient of performance (SCOP) of 4.86 at low temperatures and 3.56 at high temperatures. Its temperature coefficient (COP) is 4.3.
The medium-sized product has the same dimensions as the other two models, but weighs 90 kg. Its COP is 4.5 and the SCOP is 5.32 at low temperatures and 3.97 at high temperatures.
The largest device has the same dimensions and weight as the medium model and the same COP. The SCOP is 4.82 at low temperatures and 3.71 at high temperatures.
All products use R454B as the refrigerant, which has a global warming potential (GWP) of 466.
The heat pump has a five-year product warranty and is equipped with frost protection at the bottom source and early warning of anomalies.
Corab offers the heat pump with no installation or drilling costs.
“Owners will have to use external installers and drill holes up to 60 meters,” says Odrobinski. |
