Research Status and Trends on Industrial Heat Pump and Network Utilization of Waste Heat
摘要
Abstract
Plenty of low-grade heat is produced duringindustrial energy consumption.Waste heat reuse significantly contributesto energysavings ifhigh-efficiency technologies are employed for heat recovery.Heat pump technology allowsfor temperature upgrading and capacity ex pansion of industrial waste heat.The recovered heat can then be supplied to industrial processes orused in district heating and cooling.In this paper,the characteristics and development trends of vapor compression heat pumps,sorption heat pumps,and chemical heat pumpsare introduced.These three heat pump technologies have been greatly improved interms of working fluid,cycle optimization,and system innovation.Nonetheless,there are some incompatible optimizing targetsassociated with capacity,energy efficiency,temperature lift,and stability.Moreover,the applications and characteristics of industrial waste heat vary depending on its category and temperature grade.Design guidelines suitable for different waste heat conditions are lacking for heatrecoveryequipment and systems.Further research should focus on heat pump technologies characterized as high efficiency,large capacity,and high thermal adaptability,stability,and reliability.In addition,general design principles should be developed for mutually complementary applications of different heat pumps.Meanwhile,the high-quality integration of heat recovery systems can be accomplished to realize the highly efficient use of industrial waste heat by means of energy network utilization,including heating,power generation,cooling,and storage and transportation technologies.关键词
