Alaska researchers are testing a new LG air-source heat pump prototype designed to effectively heat homes even at -30 degrees Fahrenheit. The test is part of a larger effort to deploy heat pumps in northern Alaska as a way to reduce reliance on fossil fuels.

National Renewable Energy Laboratory Fairbanks campus Chief Scientist Tom Marsik describes how the lab is testing LG's new air-source heat pump prototype, which is supposed to be an effective home heating tool down to -30 degrees Fahrenheit.That’s one question Alaska researchers are asking of a new heat pump prototype this winter.purports to heat homes effectively even at -30 degrees Fahrenheit, and may soon do so for hundreds of residents in northern Alaska .

“You can see it right here,” Marsik said as his footsteps echoed on the hard floor. “So that’s the outside unit of the heat pump,” he added, directing his gaze at a microwave-sized metal box with a fan on its backside.“We can see the indoor unit hanging here on the wall, the indoor unit of the heat pump. We can see lines connecting it, going through the wall, connecting it to the outside unit,” he said.

Marsik explained that the technology works by capturing heat from the air – however cold the air may seem – and then sending it inside to warm up a space. The process is like refrigeration – which removes hot air from an enclosure to keep it cool – but in reverse. But, Mathiasson, the energy manager, said that capability could come with its own set of limitations the borough needs to assess before making a final selection on the model.
