Haier extends nanotech cooling deal

USA/CHINA: Air conditioning manufacturer Haier has signed a second two-part license agreement with US nanotechnology company Dais Analytic for a new cooling product.

The product, PolyCool, a cooling tower system, employs Dais’ nanomaterial Aqualyte to efficiently remove heat from the Haier cooling system.

Dais first entered into a multi-year, exclusive license agreement with the Haier Group in July 2017, to provide its Aqualyte nanomaterials for use in select refrigeration products.

The PolyCool condensing unit is said to replace energy consuming, breakable components in today’s products, and offers higher efficiencies, improved functionality and lifetime. The technology is said to be nearing full commercialisation.

PolyCool is said to reduce energy usage, maintenance, and operating costs of cooling towers and evaporative condensers for HVAC, industrial processes, and power generation applications.  The Aqualyte membrane is said to prevent the release of dangerous microbes such as legionella from evaporative cooling systems, opening new markets that have traditionally been sensitive to liability and maintenance concerns, such as smaller air-cooled HVAC systems. 

The fouling resistance of Aqualyte membranes is also said to allow the use of concentrated wastewater in evaporative cooling, making PolyCool a viable method of waste disposal, as well as providing cooling.
