Johnson Controls Turns Waste Heat into Fuel for China

November 10, 2014 By Linda Hardesty

Johnson Controls energy manageJohnson Controls is introducing a new central heating technology in China to reduce pollutants. The York Dual Steam Turbine (YDST) heat pump recycles surplus heat from industrial or power plants into higher temperature hot water that can be used to operate large central heating plants. Compared to traditional boiler heating, the YDST can reduce coal consumption by up to 30 percent while supplying the same amount of heat, says Johnson Controls.

The YDST is a centrifugal heat pump – driven by a steam turbine, not electric – that supplies over 100 MW of heat per heat pump system. It can accept waste hot water as low as 50 degrees F to 120 degrees F and increase the temperature to over 200 degrees F.

Johnson Controls says it has successfully implemented its heat recovery system at a large northeast Chinese municipal heating facility, saving more than $1.2 million while alleviating the need to burn 9,200 tons of coal in the last heating season.

Recently, the company opened an expansion of its manufacturing and research and development center in Wuxi, China. The campus will spearhead continuing innovation on heat recovery for the global market.
