Johnson Controls presented the York TITANTM Multistage Centrifugal Heat Pump, YDST Single Stage Centrifugal Heat Pump and Waste Heat Recovery Central Heating Solution at the 4th China International Distributed Energy and Storage Technology Equipment Show. It is understood that by recycling low-grade heat generated in industrial processes and producing high-temperature hot water for municipal centralized heating or process heating, it can reduce up to 50% of coal consumption and help green heating, and can be widely used in thermal power plants and enterprises Owned power plants, municipal wastewater treatment plants, industrial and mining enterprises and petrochemical and other fields, providing a new solution for energy-saving emission reduction, improve economic efficiency and control smog, aroused great attention of visitors and the industry. In most parts of northern China, the heating of urban and rural buildings mainly relies on coal combustion, and the combustion of coal generates a large amount of pollutants into the air and becomes the main source of air pollution in our country. According to Beijing Municipal Environmental Protection Bureau data show that in January this year, Beijing fog and haze in the PM2.5 pollution caused by coal-fired central heating, accounting for more than 50% of the total, even more than the vehicle exhaust pollution. Visible, the key to managing smog is to reduce dependence on coal-fired heating. In response, Johnson Controls ground-breaking ground-breaking solutions for industrial waste heat recovery can provide a range of heat from 400 to 100 MW, hot water temperature range from 50 ℃ to 110 ℃ a full range of heat pump systems, including Motor-driven and steam-driven mechanical heat pump and absorption heat pump to meet the various types of industrial waste heat recovery and cooling / heating applications. Johnson Controls is the only company in the country that has a full range of heat pump products, including centrifugal and pump-driven centrifugal and motor-driven heat pumps, as well as one of the largest heat pump suppliers in the world. The company's industrial waste heat recovery program has successfully helped enterprises in China and other countries to achieve energy-saving emission reduction targets and achieved comprehensive economic, environmental and social benefits. Wu Song, General Manager and Chief Executive Officer of Johnson Controls Building Services Business in China, said: "Based on a series of market research and innovative research and development, Johnson Controls tailor-made the waste heat recovery based on industrial-grade high performance centrifugal heat pumps based on the needs of the Chinese market Central heating solutions are expected to be rolled out to other countries from now on to meet the common needs for waste heat recovery around the world. " Taking the case of the waste heat recovery centralized heating project of municipal sewage in northeast China as an example, high temperature hot water is prepared for the urban central heating by recycling the low grade heat in the sewage of the sewage treatment plant through "industrial waste heat recovery heat pump technology". Johnson Controls provided a steam-driven multistage centrifugal heat pump unit with 22.8MW of heat for the project. By extracting heat from the wastewater at 12 ℃ and heating the municipal pipe network for hot water, the heating capacity was increased by waste heat recovery 17.3 MW, equivalent to about 34 million square meters made "free heating." Throughout the heating period to achieve savings of 9200 tons of standard coal, saving energy costs 7.36 million yuan.
