Commercial Application of Polyurethane Insulation Using HFO Blowing Agent

Whirlpool Corp., the world’s largest producer of major appliances, has begun the first commercial use of a polyurethane refrigerator insulation system with a HFO (hydrofluoroolefin) blowing agent. The polyurethane is a new formulation of BASF’s Elastocool rigid foam. It is used with Honeywell’s Solstice liquid blowing agent (LBA), an HFO with an ultra-low global warming potential (GWP) of 1. Traditionally used hydrofluorocarbons (HFCs) have GWPs between 700 and 1000.

Whirlpool is using the new insulation system in a line of consumer refrigerators. It is the first time that this type of system has replaced a traditional HFC-based foam blowing agent in residential appliances. The new Elastocool/Solstice insulation system is designed to provide several advantages, including improved shelf life stability of materials, and that gives Whirlpool plants increased operational flexibility. The system gives the Whirlpool refrigerator a 2-3% overall increase in energy efficiency, due to its better insulating properties. It provides better foam distribution during production, for more consistent and uniform energy efficiency. The system also offers reduced de-mold time during production, which the appliance maker can leverage to reduce cycle times and improve plant throughput. However, Honeywell, the Whirlpool supplier, believes its LBA offers better energy efficiency improvement than cyclopentane. It points to a trial conducted Whirlpool, in which 600-liter residential refrigerators and freezers using an optimized Solstice LBA showed significantly better energy efficiency improvement than did cyclopentane.

Refrigerator Blast Kills 3 Of Family – Repair Your Refrigerator Now

Three members of a family were killed when a refrigerator compressor exploded in their house at Vilanthai village in Villupuram district in the wee hours of Tuesday. Police said P Kandavelu, 43, headmaster of a government school, his wife K Suganthi, 38, and mother P Parvathi, 70, a retired teacher, suffocated to death as thick smoke filled the house soon after the blast. While Kandavelu’s eldest daughter, K Malathi, 21, an engineering student, managed to get out of the house to seek help, his differently abled third daughter, K Sindhuja, 12, was trapped in the house and sustained minor injuries. Sindhuja is undergoing treatment in a government hospital. Police said Kandavelu, headmaster of a government primary school at Adurkelapakkam village, and his family members were sleeping when the blast occurred. Police suspect that the refrigerator connected directly to power socket without a stabilizer might have exploded due to high voltage, triggering a fire that was fuelled by the leaking gas from the compressor. The refrigerator was destroyed completely. Several household articles were destroyed in the fire but the house was not damaged.

Now You Have an Oppurtunity to Put Ads in Your Refrigerator, Thanks Google!

Remember how advertisements were crammed into Tom Cruise’s every waking moment in Minority Report? That, apparently, is Google’s vision of the future.

In a letter to the Securities and Exchange Commission disclosed Tuesday, the tech giant revealed that it has hopes to place marketing messages in currently ad-free objects like refrigerators and thermostats. “A few years from now, we and other companies could be serving ads and other content on refrigerators, car dashboards, thermostats, glasses, and watches, to name just a few possibilities,” the company wrote. Earlier this year, Google also bought Nest, a company that manufactures smart thermostats, for $3.2 billion. At the time, Nest said that it would not broaden its privacy policy, which currently limits use of users’ personal data to “providing and improving Nest’s products and services.”
