LG air source heat pump Thermal V 200L and 270L
With the ability to heat 200 to 270 litres of household water, LG has created an air source heat pump. The pump has a coefficient of performance(COP) of up to 3.85 and utilises R134a as the refrigerant.
The latest series of household water heating heat pumps was unveiled by LG Electronics in South Korea. They can be put in bathrooms, laundry rooms, kitchens or garages.
There are two models of the Thermal V, each of which can heat 200 or 270 litres of water. The COP for the 200 litre variant is 3.30 at 7C and 3.50 at 15C. The COP for the 270 litre model is 3.45 at 7C and 3.85 at 15C.
The electric heat pumps have a power input of 2kW at 230V. The 200 L model has an annual energy consumption of 755kWh at 7C and 709 KwH at 15C.
According to the product page for LG, the air source heat pump consume just 25% of power and 75% of air energy to heat water. The compressor is an LG Dual inverter compressor with two rotors.
LG states in the product’s data sheet, twin rotaries balance each other while revolving at high speed, reducing noise substantially compared with the shaking single rotary compressor. The noise level of LG heat pump is 53 dBA, which is comparable to refrigerator noise.
The Thermal V 200L weighs 100kg and has dimensions of 580 mm by 1,625mm by 582mm. The 270L model weighs 119kg and has dimensions of 580mm by 2,008mm by 582mm.
They can work in conditions as low as -5C and high as 48C. The equipment makes use of R134a, a refrigerant having a 1,430 global warming potential(GWP). The water tank and compressor of the new system are covered by a 10-year guarantee.
LG heat pump operates even in severe cold
Even if very gusty winds and over bitterly low temperature are predicted, overnight and through the weekend, most of the time, heat pumps are quite effective at both heating and cooling.
Many heat pumps on the market today can function in -30C temperatures, but some may struggle to generate enough heat to keep a room at a comfortable temperature when outside temperatures fall below -30C.
Residents of Island should utilise their supplementary heating system such as electric resistance or oil/propane heating systems in addition to their heat pump if they are having problems keeping their home warm on freezing days with a heat pump alone.
Heat pumps do not need to be turned off by people.
Residents should check that their additional heating systems are turned on and working. Lower the thermostats by one or two degrees compared with heat pumps.
This will guarantee that supplemental heating systems will turn on and make up the difference to keep their house warm if heat pumps are unable to cope with the excessive cold.
Remove any snow and ice accumulation from the outside until if it is safe to do so. You’d better get in touch with the installer or manufacturer for guidance on your particular heat pump models.
Communal heat pump networks might be the solution for decarbonising heat in both metropolitan high-rises and other difficult-to-heat residences, from New York City to rural Cornwall.
