Chinese Appliance Maker Uses Energy Efficient Insulation Process

September 25, 2014 By Linda Hardesty

Honeywell Energy ManageChina-based Haier will adopt Honeywell’s new Solstice Liquid Blowing Agent (LBA) to help insulate and increase the energy efficiency of its refrigerators.

Blowing agents such as Solstice LBA allow closed-cell polyurethane foam insulation to expand and provide the majority of the foam’s insulating properties. Solstice LBA can help appliance manufacturers achieve an 8-10 percent energy efficiency improvement compared with cyclopentane, which is widely used as a blowing agent in appliance insulation, says Honeywell.

The company says it has been working with Haier for the past three years under their Open Innovation System to transition to Solstice LBA.

Solstice LBA has an ultra-low global warming potential of 1, which is 99.9 percent lower than HFC-245fa, a commonly-used blowing agent, says Honeywell.

The foam insulation used in the Haier refrigerators is formulated and manufactured by Dow Chemical.

Solstice LBA is nonflammable and is not a volatile organic compound. It is approved by the US Environmental Protection Agency under the Significant New Alternatives Policy (SNAP) Program and is also registered under the European Union’s REACH program. Honeywell’s new world-scale production capacity manufacturing plant for Solstice LBA started up in May 2014.
