LG produces an air supply warmth pump with the capability to warmth 200 liters to 270 liters of home water. It makes use of R134a as refrigerant and the pump has a coefficient of efficiency (COP) of as much as 3.85.
South Korea’s LG Electronics presents a brand new line of water heating warmth pumps for residential functions. It may be put in in garages, kitchens, laundry rooms, or loos.
Therma V has two variations, with a capability to warmth 200 liters or 270 liters of water. The 200-liter mannequin has a COP of three.30 at 7 C and three.50 at 15 C. The 270-liter mannequin has a COP of three.45 at 7 C and three.85 at 15 C.
Electrical warmth pumps have an influence enter of two kW at 230 V. The 200-liter mannequin has an annual vitality consumption of 756 kWh at 7 C and 709 kWh at 15 C. The bigger mannequin makes use of 712 kWh per 12 months at 7 C, and 646 kWh per 12 months at 15 C.
The air supply warmth pump makes use of 75% of the vitality from the air and solely 25% of the electrical energy to warmth the water, based on LG’s product web site. It options LG’s Twin inverter compressor, which operates on twin rotors.
“As the dual rotaries stability one another as they rotate with excessive velocity, this reduces the noise considerably in comparison with the oscillating single rotary compressor,” claims LG within the product’s knowledge sheet. The warmth pump produces a noise of 53 dBA, which is equal to the noise of a fridge.
The Therma V 200L measures 580 mm x 1,625 mm x 582 mm and weighs 100 kg. The 270 L mannequin measures 580 mm x 2,008 mm x 582 mm and weighs 119 kg. They’ll function at temperatures from -5 C to 48 C. The gadgets use R134a refrigerant with a worldwide warming potential (GWP) of 1,430.
The brand new answer has a 10-year guarantee for the water tank and the compressor.
