Prospect of CO 2 heat pump applications in China Youhua Tian Peking University
ROAD MAP 1.BACKGROUND 2.PRINCIPLE OF THE CO 2 HEAT PUMP 3.ADVANTAGES OF CO 2 HEAT PUMP 4.APPLICATIONS OF CO 2 HEAT PUMP IN NORTHERN CHINA
BACKGROUND OUR ENTREPRENEUR GROUP 1.Professor Zhang (CTO, Expert at Heat Pump, Inventor of the ultra-low CO 2 air source heat pump) 2.Youhua Tian (CIO,Urban and Environmental Sciences, PKU) 3.Zhenguo Zhang(CEO, Former General Manager of Xuyue-- ) 4.Bo Hu(CFO)
BACKGROUND Why Heat-pump? coal-fired boilers Zhenguo Zhang: Coal transportation &trading company Bo Hu: Whos father-in-law is a boiler maker
BACKGROUND Hazy weather in winter When PM2.5 over 400, all companies making smog are forced to STOP PRODUCTION
At the very beginning, we intend to replace coal- fired boilers with heat pump to reduce smog. What is the contribution of coal-fired gas to total carbon emissions?
BACKGROUND Energy Consumption Structure in China, 2013
BACKGROUND Some of the pollutants responsible are sulfur dioxide and nitrogen oxide emitted by coal combustion, which provides 70% of Chinas energy and 80% of its electricity, and is primarily used by coal power plants, heavy industry such as iron and steel and cement factories, and for residential heating in the winter. Flue gas produced by factories and residential heating is discharged directly into the atmosphere without any treatment.
BACKGROUND Beijing requires over 20 million tons of coal each year.
What is CO 2 -heat pump looks like? 2m 1.8 m 1.2 m The first generation of our product
WHY THE COST IS SO CHEAP? Because the COP(coefficient of performance) of heat pump is about 4.0 (2.8~7.0) 1 Joule 4 Joule 4~5 Joule of heat from heat sources (air, water …)

3. Produces high-temperature (97 ) water within 1 minute
Three types of heat pumps Exhaust air heat pump(EAHP) Extracts heat from the exhaust air of a building, Water source heat pumps (WSHP) Uses flowing water as source or sink for heat Hybrid (HHP) Uses twin source for heat
cold Cold air or liquid water heat Hot Water/air Core technology we can produce heat and cool energy at the same time
APPLICATIONS OF CO2 HEAT-PUMP IN NORTHERN CHINA
12 RMS/m2 in Zhengzhou for the entire heating season 1. Winter heating & Summer cooling
2. Industry Widely used in factories which need heating and cooling at the same time, especially high- temperature water (>70 ) and low-temperature air/liquid (<-20 ) When PM2.5 over 400, all companies making smog are forced to STOP PRODUCTION
Slaughterhouse Needs 65 hot water for washing and 0 cold air for keeping fresh meat They used coal-fired boilers (prohibited now) to get hot water and air refrigerator to get cold air Saving 1 million RMB each year
Chemical Plants Each production line needs 100T 90 hot-water to accelerate chemical reactions and 400T 40 cold- water to prevent explosion. Also needs 200T -20 cold liquid to keep products. Saving them 6-8 million RMB each year
